1991 240 Volvo -- car stalls every once in a while while driving it under 50 miles per hour. My daughter will be driving along and it seems to slowly lose power/fuel (??) and then die -- She can coast to the side of the road, sometimes it starts right back up and other times it will take maybe 5 trys to get it running again. I have had this thing in the shop for days at a time. They did find a frayed wire on he crank positioning sensor and we replaced that but the problem came back 3 weeks later. It seems to happen every 2 weeks -- 3 or 4 times, go away for a week or two and come back. I am going to replace the fuel pump relay today, have already replace the fuel filter and checked the fuses. This is a very frustraing problem because it is my daughters car and I am afraid for her when the car stalls. Please help if you know the fix --

I fixed this problem on my 91 by replacing my 25amp fuse and holder. It was corroded beyond cleaning.
The 91 still had that fuse.
Easy enough to find and inspect. Tucked in between the battery and the coil

Odd, I though 1990 was the last year...

Yes, 1990 was the last year. Chassis -429799 sedan and -883199 wagon. But there's always someone with an exception or mistake.

And finally, there was the person who sent nineteen different puns to his friends, with the hope that at least ten of the puns would make them laugh. No pun in ten did. Oh...man!

I second the Fuel Pump Relay.
Any chance your daughter hits that same Pothole when the car dies? If you have hairline cracks in that relay a hard bump might 'break' the connection.
'91... I think they did away with the 25 amp fuse under the hood by then, That would have been my next thought. That Fuse and Fuse holder are suspect for bad connections.

I have a gorgeous 1991 240GLE Limited Anniversary Edition Sedan which has me breaking out in hives now I am sooooo frightened ... to drive it. She went so well for about 7 years and then ... she was possessed, by something, I don't know what, to this day.

1st mechanic replaced the 'Main Fuel Pump' ($679.00), but it still kept intermittently stalling (usually on a busy highway so lots of people can abuse and honk at me) ... then he said it must be (& replaced) the 'In-Tank Pre-Pump' ($350), together with all new Fuel Lines and Hose Clamps just in case, she still kept stalling ... replaced the Battery - well 'it' could be faulty, so brand new $258 NRMA Battery ... she still kept stalling - then mechanic said ah-ha it's the faulty 'Ignition Lead Set', yup, he put a new Set in plus new Sparkies ($168) - still kept stalling ... Now I take her for a 2nd opinion and 2nd Mechanic said it's for sure the 'Ignition Module', they go all the time on these models ($372.75) and new Sparkies also just in case ... she still kept stalling, hmmmmm, must be the 'Starter Motor' ($698.35) - yep, she still kept stalling, worse than ever actually, 3rd go he 'Removes Body Sealer Fuel Tank' ($114.95). AND SHE KEPT STALLING. 2nd mechanic has had her now for a week, and it's funny because usually when I drop her off she doesn't play up. This time she did and exonerated me. But it took her 5 days before she 'did the deed' on 'him'. I really really love this car but I'm so frightened now. I've ordered a new 'Fuel Pump Relay' from the UK (neither mechanic suggested that) but from reading BB well, it 'could' be that. Wow, almost $2,500 later and no-one can fix my big-baby. Any suggestions please would be so welcome !!! Thanks ever so much.

You should probably start a new thread for your problem rather than resurrecting a 6 year old one.

The fuel relay would have been the first thing I tried and may solve your problem.

The crank position / RPM sensor would also be suspect, especially if the insulation is cracked or missing on the old one.

Clean and tighten all the fuses in the fuse box.

Dump the mechanics they aren't looking out for you.

Dear Dan,

Just a note to say THANK YOU Thank You THANK YOU ...

I picked her up from the mechanic and this time he said he fixed something 'electric' from somewhere underneath my driver's side. All I can note is that my Immobolizer-Alarm now does not work.

I ordered the FUEL PUMP RELAY (as you suggested) from a reputable UK-based Auto Seller and my Qantas-Engineer neighbor very kindly fitted it for me.

BINGO ... she goes like a dream and SOOOOOOO QUIET. She's like a new car !

Thanks so much again Dan. Much much appreciated.

And it makes me so sick to think I outlaid over $1200 to this highly-recommended-mechanic, for nothing.

Have a great New Year and cheers for helping me help my beloved brickstar.

"this time he said he fixed something 'electric' from somewhere underneath my driver's side. All I can note is that my Immobolizer-Alarm now does not work."


did you tell any of the previous mechanic that you had an Automatic Kill Switch Alarm installed.?

Yes, first thing I did ... and showed both where the kill-switch was located.

It was professionally installed over 7 years ago.

However, the car started playing up only in the past few months. But going beautifully now. So quiet she's like a new car.

Cheers,

GM

Thank You so much Dan for taking the time to reply/advise - it's much appreciated I assure you.

I couldn't find anywhere to start a new post - my 'page' seems to be full of bloomin' KOGAN ads ... that's why I tagged on-to that particular thread and hoped and prayed someone would read it and help me.

Cheers and Thanks again Dan,


Gina

Did you get the car fixed? Let us know what solves the problem, it may help others in the future.

Dan

Dear Dan,

I can't THANK YOU ENOUGH for your very kind and very quick reply-post (and-FIX) to my 1991 240 intermittent-stalling problem.

YOU GOT IT IN ONE - sentence.

' The fuel relay would have been the first thing I tried and may solve your problem '

Bingo. That was all it was. She just needed a new Fuel-Pump-Relay.

Runs like new, she's fabulous, and I do love the ole girl.

THANK YOU again Dan, so much !

Kindest Regards,

Gina M.

It is usually the simple things that most often fix these cars, glad you are back on the road.

Your Bentley or Haynes manuals tells you, as well as the FAQ:

https://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm

1991 and newer does not have the behind the battery inner fender mounted blade fuse for K-Jet equipped 240s. That fuse is in the fuse box.

Unless yours was built in 1990 yet was sold as a 1991, I guess.

Egg Nawg Boyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy.

I was here and there, also.

1991 Volvo 240 forever! I own one! Drove it to work today. HA!

Cool, like the 1979 model year 240. You have the 242 GT in there.

Replace the Fuel pump relay yet? Sounds like it is on the way out.passenger side of the firewall under glove box. If it is the original relay in the vehicle it is most likely your problem and soon it will not restart at all.

Things to check,

Fuel Filter, replace if old.

Listen to the pumps when you turn on the key, quick hum of the pumps pressurizing the fuel line? The pick up pump in the tank could be going out, or debris in the gas tanks could be clogging up the sock on the pickup pipe. I jumped the pumps with the key on, did not start the engine, just let them run and listened. You could hear a surging or whooshing sound where the pickup pumps was not supplying enough gas in my case.

Check and make sure the catalytic converter is intact and not starting to plug up. Sometimes you can thump the cold converter with the palm of your hand and things will be moving around.

Clean your throttle body.

Check your large intake hose for cracks or splits, replace as needed. Make sure all the vacuum lines are properly attached, and all the clamps are tight on the big hose.

Pull the vacuum line off the fuel pressure regulator and if you smell a gas odor replace it.

Disconnect the negative wire on the battery, then check and make sure the AMM connector is firmly seated on the connector. Reconnect the battery and see if that helps any.

Hope this helps,

Paul
