1995 850 TURBO Wagon
Have replaced fuel pump relay and shift sensor
Problem:
1) Starts and runs drives fine but if I stop for any reason and turn off the engine it will not restart.
After about an hour it will re-start.
2) On occasion the car wil be running and a P code comes on reporting a "incorrect gear ratio”-I reset the code and all is well until the next time.

Yes, try posting in the AWD section of the BB. See AWD button on top or side of this webpage.

Your problem sounds somewhat similar to a problem I had with my 95 850. It would start fine when cold but not when warm. Turned out it was the starter.

Will I buy another Volvo??? We'll see....

I know little about the 850 but I agree that it sounds like the starter. My old 1979 Olds Delta 88 with a 350 Olds engine, son's 940, and then there was the frantic co-workers Toyota whatever car in the parking lot. Solenoid stuck, dried out lubrication, rubber bushing in there somewhere that swells when hot...

This may or may not work, all three cars were restarted with a "tap" or 2 with a metal tool such as a tire iron or what ever can reach.

BTW, son was happy and used the tap method for a month or more until he, at his leisure, could get the car over to my house.

You are right on the money. It was a stuck solenoid!

Dear Carnage,

Hope you're well. As your car is an 850, you should post on that part of this website. The 900 series cars are totally different: four- versus five-cylinder engines, rear-wheel drive, etc.

Hope this helps.

Yours faithfully,

Spook
