1988 volvo 760 turbo - trouble

I'v had that same issue. It turned out the be the fuel pump. I replaced the one in the tank as well as the one under the driver seat under the car.

Immobilizer is shutting the car down most likely. Try a different key see if it happens to the other key or bring it to volvo and have them get a new key for it. And have them check the anntenna for the immobilizer. The immobilizer system will shut the car off if it does not sense the correct wireless signature from the key, after a few seconds. You can take the key out of the ignition then reinsert it, try again see if it starts.

More common problems not volvo specific:Plugged fuel injectors maybe, turbo controller problem maybe. Or an ignition control module problem after it heats up. Hard to tell.

I used to have that same exact model and year of car and it had a turbo controller problem that would only be noticeable if at high altitude, 5000ft or above and engine under significant load( climbing a long hill) the engine would surge up and down constantly. Replaced the turbo controller and it was fixed.




Good luck with that

The bearings in the turbo may be shot. Check the shaft in the turbo if you can wiggle it around its bad and will need to be replaced or rebuilt.

with a bad fuel pump, you wont get enough fuel, so you cant get the power.

You have 3 choices. 1 buy one from the dealer, 2 buy one at some place like Best Buy also buy an installation kit, 3 buy one at a junk yard.

Check starter connection. Mine does the same thing. Also check belts. A pressure hose could be unattached. Right above the starter there is a hose. Check all of them to make sure they are hooked up.

TRY ANOTHER FUEL PUMP AND FUEL FILTHER THESE PUMPS ARE FUNNY ON VOLVOS HAD SAME PROBLEM ON 850 TURBO AND SURE ENOUGG IT WAS THE PUMP

check your fuel regulator and in-tank pump

welcome to fixya

no fuel to motor could mean the fuel filter or fuel pump

if you checked these then try the timming sometimes in newer cars the timming has a effect on it .....


hope this helps you out have a good day
