Keeps dying on me

not sure but it could be a throttle body problem as this controlls the the acceleration and tick over

you have to check you engine starter (dispositive that is made to turn on your car)

i have heard somewhere that this is caused by a faulty vacuum check valve which is black and white plastic and is located near centre above the rear of the engine up against the firewall. vacuum drops when you accelerate so there is not enough vacuum to keep various vacuum operated heating/cooling system valves in their selected position . the check valve keeps sufficient vacuum in a reservoir tank when vacuum at the engine manifold drops.

Sounds like it could be the mass air flow sensor.
Have vehicle scanned for codes and use shop manual to conduct the correct tests on that sensor .

I am a volvo tech and your problem is fuel pressure ralated and i had same problem in 1995 850 turbo and the fuel pump was the problem and a used one is around 35.00

Under you car,just in front of the main fuel filter,why are you replacing it?

1st thing, check the relays, behind the ashtray, give 'em a gentle twist, while turning the engine.
Bon chance.

ok, this used alternator has bad diodes and will need them replaced. sometimes, certain technicians wont rebuild correctly. they just look over this vital part. i would return this alt.

First check for holes or disconnected air inlet hoses, that will give the sensor/meter a problem so it cannot send the correct signal.

two things to check,,, there is a crank sensor at the back of the engineby the bulkhead,,at the top of the engine where the gearbox joins ,,,the sensors are known to be faulty if sometimes ,,, check the cable to the sensor,,if it is damaged replace the sensor,,,the other common problem is the fuel pump relay,,, behind the fusebox in the dash
