Question about Volvo 240

1 Answer

I have a 1991 Volvo 240 wagon that intermediately shuts off while driving. When it does shut off the lights on the dash turn on(don't know if that piece of info means anything). Also most of the time when I try to crank it back up immediately after I pull over it takes a while before it wants to run again. Anyways the funniest thing about it to me is that it runs good like a champ-until it shuts off at random. I've checked some of the fuses that where underneath the dash at the drivers side door-they looked good, and I haven't been able to figure out where the fuel pump relay is on the vehicle but I'm guessing that it's in fair condition. The fuel filter has been replaced but the pumps have not been replaced. I've also thought about checking some of the ignition system components but i don't know if that would help with diagnosing the problem. My first question is that: Is there a solution to the intermediate shutting off that will fix that problem for good? My second question is that: Is the problem some where in the Fuel System, In the Ignition System, Or Both?

Sometimes the wires that go to the dist behind the cylinder head break loose from dist and short out on dist body. also there is a single fuse on left[as viewed from drivers seat] inner fender near the top. its in a holder with a rubber cap over it. the fuse holder gets hot and the connections in it melt and cause problems loke yours. if you pull the fuse and see heat damage sut out the fuse holder and splice in a new one.make sure the replacement has the same guage of wire or bigger on it.

Where is rollover switch on 1991 240 volvo station wagon

I don't think there is a rollover switch on a '91 wagon.
The ECU supplies ground to the fuel pump relay for only about a second and a half if there is no ignition pulse. This is what shuts off the fuel pump in the event of an accident. The transistor in the ECU that provides this ground signal fails after a couple of decades. Repairing it is not a do-it-yourself operation but there are rebuilt ECUs available from multiple sources. Be sure to get an ECU that is compatible with your vehicle configuration.

My 1991 Volvo 240 would shut off while driving, but would always restart. This morning it won't turn over. I noticed that the headlights flash systematically while I'm trying to start it. Not sure if... take your car to a mechanic and check if the fuel pumps are runnin efficiently...lack of and inconsistent fuel supply to the engines may lead to your engine dying as you drive..i'm sure this is observed especially in cold mornings..i had that problem too but now after getting it replaced...its ok

Headlights go out while driving

You need to check the headlight relay to see if it is still good. Parts store can tell you where it should be and what the part number is when you find it. A good shop will be able to test it. I have found that Volvo likes to play hide the relay under the dash so it's hard to say for sure where it will be.

I have a 1991 240 volvo that the break lights are not working

If its not the fuse. Check the switch. It's under the dash and when step on the breaks a plunger comes out. Make shure it's not stuck. If you have an ohm meter check the switch.

Starting in damp weather 1993 240 wagon, auto/od, 235k miles

perhaps you need a new cap and roter a new spark plug wire set. they don;t like moisture. also check to see if you have any broken or leaking vacuum hoses. the worse case senerio would be that your head gasket is leaking--at cold temps a little antifreeze will enter until everything warms up and it seals shut due to metal expanding. but since you say it's cold weather only--this probably wou;dn't be the case. good luck.

Had the exact same problem with my 240 wagon. There is a temperature sensor up near the manifold on the drivers side of the engine. This is not the temp sensor that feeds the dash gauge, but one that tells the engine control module whether you are starting hot or cold. Mine was cracked, so the engine computer would get a cold start signal even after the engine ran warm, and would flood. This can be a difficult problem to diagnose and an expensive one when mechanics start swapping parts. You cannot see this sensor, but you can feel it (when the block is cold, please) right under the exhaust manifiold. A replacement is about $80 plus labor. Even my very experienced Volvo mechanic overlooked it. But the car would start and run fine, then leave me stuck when I tried to restart it. After calling AAA for a tow, the temp sensor would reset, then the car would start normally. Cheers. The 240 is a great car - I ran mine up to 235,000 miles; now I have a 740 with the same engine.
