FUEL INJECTION, FUEL PUMP,
OVERDRIVE
& OTHER
RELAYS
and CRANK POSITION SENSORS
| Volvo 240s and 740s
are well known for their reliability
and for going many years and miles longer than most other cars.
But
some of their CRITICAL
RELAYS are known for failing sometime after around 10 to 20
years of
service. I don't really know if these relays were built that
poorly.... I think it might be the cars are so well
built, they simply outlast some of their electronic components. So, at least for Volvos, it appears there are some relays that can be considered "wear items." If
one of these critical relays
fails away from home, it could be costly (high towing expenses, wild
mechanic's
diagnoses, etc.). |

Should You Carry a
Spare Fuel
Pump
Relay?: I had a 1990 740
Turbo a number of years ago. When it was close to 10
years old, it began to develop
intermittent stalling while driving, but it would eventually start
back up after a few minutes of rest. After
it
happened to my wife twice, she refused to drive the car! I
could not re-create it when searching or testing.
I figured it had to be
a relay or crank sensor, and THIS CAR HAS TWO RELAYS that are commonly
prone to
failure. So I replaced the Fuel
Pump Relay (3523608), Radio Noise Suppression Relay (1323592) and Crank
Position Sensor (3547847), all at once. Sure enough, one
of those was the problem and the car was good after that.
Because this is so common in Volvos, I keep all
three of these items in stock here just in case any of you need
them. CAUTION Regarding

Here's
a Brickboard post
regarding a couple of Radio Suppression Relay replacements.... "I purchased a RADIO NOISE SUPPRESSION RELAY for my 87 740 Turbo wagon a couple of months ago, and thought I'd drop you a note to tell you that the car has been running great, I've been driving it every day for about the last month, with NO STARTING ISSUES!!! It was having intermittent starting issues, would be fine for a few days, then leave me stranded. I had replaced both fuel pumps and the fuel injection relay. It would start with a shot of starting fluid, then be okay for a few more days. I would have never thought that a radio noise relay would have an effect on my fuel injectors, but thanks to your site and all the information on it, I was steered in the right direction. You saved me from scrapping out a car that i truly enjoy to drive." C.W. "Dave, thanks for posting this information on how relays can interfere with ignition. I had a gradually worsening stalling problem over the past year and a half. The mechanics could not trace it, since the stalling was never associated with a "check engine" light (good mechanics but not Volvo specialists). The symptoms usually were a failure to restart after a short stop, but it eventually worsened to stalling in traffic. I guess the engine heat would cause a bad solder joint to open up and block spark to the engine. I replaced the various relays you mentioned and I have not had any stalling since then. I wonder if a Volvo specialist would have diagnosed the problem earlier? In this case I took your suggestion to the mechanic, and he admitted it would not have occurred to him. Definitely bookmarking your site for future reference!" M.L. "Hi Dave. Well probably no surprise to you....the car is working fine now after three months of pulling my hair out, 2 tows and 8 trips to the mechanic. You're right...too few know of this fix... I'm mechanically inclined, yet can't believe I solved this one with your help with relays from Hungary... of all places...amazing. The car currently has 145K and is a honey. Your the best." B.L., Martha's Vineyard, MA "Hey Dave, Thank you so much. Your hypothesis that failing relays causing intermittent problems was spot on! I replaced the Overdrive Relay and it instantly fixed my phantom shifting/not shifting overdrive problems also, the car seems to auto shift at the appropriate times and RPM's more precisely, the way I remember it did. Then I replaced the Fuel Injection Relay and the intermittent stalls have disappeared - a major boost of confidence before Holiday travels! Holding off on the Noise Suppression Relay and Crank sensor for now because it's running so well! I did a lot of web crawling before I found your site and can confirm there are lots of 740 owners with the same issues - most seem to spend a bunch on Fuel Pumps and Mass Air Sensors and just about everything else, often without success. I'd encourage you to post on the various boards out there regarding Intermittent Stalling and Overdrive issues... $80 for the two relays I installed in a couple of minutes and a now in a world of Volvo goodness!" E.S., Blue Lake, CA "I had a great outcome with the C70 – I called my mechanic and asked him if he could replace the Fuel Pump Relay in the car. He said it could be a number of things, but I told him I wanted to start with that first since it was a cheaper resolution and after researching it on your site, I felt pretty sure that was the problem. Before, the car did the same thing when he tested it in the late day / HOT sun after sitting most of the day. Car started up and died after a minute as if it were out of gas. Then he changed the relay and I’m back up and running!! He charged me for his time and the relay – out the door for $100. I think he should have paid me for finding the problem out for him. (ha ha). Thanks again. Even though it was a C70 and not the other model Volvos – the answer was the same. I'll keep one of those in the glove compartment for sure! Your site helped a ton!! M.G. |

TESTING VOLVO
RELAYS Here is some
excellent
info on Volvo fuel pump
relays: |
| VOLVO
240 HEADLIGHT RELAYS Some 240s ('86-'93 only) are equipped with
2
different relays that control
the headlights (earlier 240s have only the one step relay).
FAILURE SYMPTOMS: You'll know it has failed if you can no longer switch between low and high beams (you can hear the audible 'click' if it's working). Also, if your headlights go OFF when in low or high beam mode (only low beams work or only high beams work), then it is most likely this relay. 2. Main Headlight Relay, '86-'93 240 only, Volvo PN 1324749 (or 1235013) (click here to see it), Bosch PN 0332015001, 0332015011, 0332015012, 0332015016. This relay is more of a mystery to many 240 owners, because it's tucked away out of sight, under the dash. In the '86-'87 240, it should be found behind the brake pedal area (see relay diagrams above). For the '88 or '89 to '93 240, it will be behind the center dash area, just below the accessory gauge locations (exact year of this change is not certain to me, but probably '88 or '89). This relay fails far less often than the above step relay. FAILURE SYMPTOMS: Headlights turn off on their own after a short time (and your fuses are good). Headlights may come back on after switching them off, then on again... or you might need to wait a while and try again (cooling off period). Or, headlights may not come on at all when the switch is turned, but your high beams will flash correctly when the steering column stalk is pulled back. |
| FAILURE
OF VOLVO BULB FAILURE RELAYS The red relay pictured at left is PN 1362370, which fits the 1986-93 240, 1986 and later 740, 780, and 1991-94 940. Other variations for 200/700/900 Volvos include a yellow one, PN 1362278 (1978-85 240 and 740 through 1985), another yellow one, PN 3545704 (1988-90 760, 1991-94 940 SE and 960), and a blue one, PN 9128814 (same 1988-90 760, 1991-94 940 SE and 960). The failure of these relays is becoming more frequent in older Volvos. FAILURE SYMPTOMS: The symptoms of failure can be headlights or tailights (or often just one side) that will not work even after verifying that fuses, switches, headlight relays and wiring are all in good order. |
| COULD IT BE
SOMETHING OTHER THAN A RELAY? What about Volvo fuel pumps? The main fuel pump in a Volvo is really well built and rarely fails (Bosch simply makes great fuel pumps). A good survival trick if you think a main fuel pump might be bad... give it a quick tap with a wrench. For best results, if possible, tap the pump when cranking the engine (while power is going to the pump). If the pump is bad, often the tap will make it come to life and it may stay running until you shut it off. This trick can get you back on the road and get you home in an emergency. If it's a bad fuel pump relay, this will NOT work as there will be no power going to your pump. If this is the case, you might try the below relay bypass "jump" trick to get power going to the pump. TESTING YOUR FUEL PUMP How to "JUMP" the fuel pump circuit at your Volvo 240 fuse panel: ![]() The fastest method to make the main fuel pump run (bypassing the Fuel Pump Relay) is by jumping two circuits at the fuse panel (left side driver's kick panel). You can make a jumper from a wire with stripped ends or even a straightened paperclip. Jump the circuits on the right side of the fuses for best results (see photo). For a 1979-84 240, jump fuse circuit #5 to #7. For a 1985-93 240, jump fuse circuit #4 to #6. If the main fuel pump doesn't begin running when jumped (you should definitely hear it humming), you either have a faulty fuel pump or faulty wiring to the pump (bad wiring is really common under an old 240, near the pump). This test of course assumes your battery is good. If one of the fuses blows during this test, the pump circuit wiring is shorting to ground somewhere between the fuse panel and the pump. More detailed info can be found at http://cleanflametrap.com/transferPump.htm. GETTING YOUR 240 HOME WITH A FUEL PUMP RELAY EMERGENCY If you find the above jump test makes your fuel pump run and you don't have a spare relay with you (or if your spare doesn't work either), here's a trick that will get you home. The simple trick of course is to jeep the jump wire (or paper clip) in place while driving. Your pump will run continuously. This won't hurt it as long as you have fuel in the tank. Keep in mind that when you turn off the car, your pump will continue running until you disconnect the jumper. Trying to secure a jumper wire (or paperclip) to the fuse panel is very difficult. There is another way. Find your fuel pump relay and unplug it. Look at the plug. There will be a RED wire going into one pin in the plug. That is the power from the battery. Also find the YELLOW/RED wires (usually two of them going into ONE pin). These go to the fuel pumps. Jumping or connecting these two pins in the plug will be the same as jumping the two fuses shown above and it will be much easier to stick a paperclip into the plug pins. IN-TANK PUMP (PRE-PUMP) ISSUES Applies to all 240/260 and many 700 models ![]() This
is a VERY common problem in Volvos reaching the age of 15 years
and
older. Often the actual in-tank pump is NOT broken, but the RUBBER FUEL HOSE
that goes from
the pre-pump to the metal feed tube inside the tank decomposes and
falls
apart after many years
of being submerged in fuel. When this hose ruptures, the in-tank
pump can no longer push fuel out. The main pump under the car will try
to
make up the
difference, but it can't keep up, especially when your tank is half
full or less, when your fuel level is at or below that
hose rupture.
A GOOD TEST: If the symptoms go away after filling the tank up, then this is your problem. Opening the top of the tank (in the trunk or cargo area) and replacing that small hose is the cure. A simple piece of 5/16 inch fuel injection hose about 3 inches long works fine. And replace those cheesy hose clamps with nice new ones while you're at it. You might be shocked to find out how many people have been advised by service technicians that they need new fuel pumps when only a short piece of fuel injection hose was needed. More
detailed info can be found at http://cleanflametrap.com/transferPump.htm.
Non-Turbo 240? - Remember to check the LH Fuse for corrosion On 1983 and later 240 non-turbos, the LH fuel injection system uses a 25 amp fuse located under your hood on the left side fender. It is not in any type of sealed fuse holder, so the elements will cause corrosion to invade the connector after a number of years. Often pulling out and re-inserting the fuse will cure this issue temporarily. For a long-term fix, clean the contacts with a wire brush, or even better, replace that fuse holder with a water-tight one, like the one found here: Volvo Harness Parts Page |

Fits '87-'92 700, '91-'95 940 & 940 Turbo. Also used as a cooling fan relay on many '88-'93 240s. Genuine Volvo part (made by Stribel). (The failure of this relay used as a Noise Suppression Relay will cause a No-Start or Intermittent Start condition) This relay is mounted under the hood, often at the right shock tower or near the coolant reservoir. For B230FT (turbo) engines this relay is often mounted near the left shock tower. On some models you will find TWO of these. In these cases one will function as a Noise Suppression Relay and the other a Cooling Fan Relay. They are interchangable and can even be swapped during an emergency if the radio suppression relay fails. If the Noise Suppression Relay starts going bad, you may get intermittent starting problems (and/or intermittant running) since the electrical pulse to the fuel injectors will be interrupted. If the engine turns over OK, but it won't fire, then this could be the problem.
