At first it would run and shut off when it got to running temperature. Now it starts at times and other times it wont start at all. But when it does start it quits right at or right before it hits the running temerature. After it cools off it will go until it gets back at the running temperature and quits again.

Re: 1990 Volvo 740 Turbos wagon
Maybe bad Power Stage/Inquiry:driving down the highway at @ 60mph with 1/4 tank of gas in 100 degree temp inwell kept 84 760 Turbo; car just dies, engine turns over but will notstart] [Response:] Well, when my '84 760 Turbo died for no apparentreason as you describe, it was in the freezing dark, going over Donner Pass.Everything on the car worked except no spark and the engine wouldn't run. It turned out to be the ignition module, which is mounted on the inner driver'sside fender well, above the battery, close to where someone else mentioned theballast resistor was located. It's easy to get to and replace. Ifthat turns out to be the culprit, shop around before buying the new part. Volvo dealers charge several hundred $$$ for this thing, but I found one froman independent parts distributor for about $90 - the identical part madeby BOSCH with the same part number on it.

Go to an auto supply store like PEP boys or Advance Auto, etc., and buy a Haynes Repair Manual for the 740. You may be able to consult one at your local library for free. Even if it doesn't cover your model year, the replacement instructions are pretty much the same for all years. in fact even a 240 Volvo manual would be essentially the same. Pay particular attention to the installation instructions....you have to slide the pump on, and then rotate it a few degrees clockwise to make the upper o-ring seal. Good luck!
sounds like you have a computer glitch. i would take it to any auto shop and pay 50 bucks so they can take a look at your e.c.u. (engine control unit) we had a similar problem a few years ago with our 1990 volvo 740 gle 2.3l station wagon. it was a glitch with the computer. got a mixed signal with the mass air flow sensor.
I had a 87 740 turbo wagon, It ran a 10.9 1/4 mile man was it fun. I hate to say that your turbo is nearing the end of its life. The only thing you can do is replace it. there are speciality shops that specilize in turbos. if you can't find one close check out a Diesel truck shop, they deal in turbos too. maybe you can have it rebuilt a little cheaper, or I can tell you how make it pass a Corvette. Good luck.
