1993
Chevrolet
Lumina Euro
3.1 Vin T
165000 about.

Problem started yesterday at red light car stalled and had a hard time getting started. Got to weekend place and car would not stay running.

The engine sill start and idle but will not run when the throttle is pushed. When car it put in gear the engine will stall.

Though the plugs and wire were the problem due to one of the wires being bad. Still have the same problem.

Have change the motor mount, oil pressure sensor, found some wires missing insulation repaired those.

You will have to check for any stored trouble codes and post the numbers here.

You can jump pins A & B of the ALDL

You also want to test the fuel pressure.

You get a fuel pressure gauge and you attach it to the service port on the fuel rail.

Went and rented the test kit and hooked it up and it topped out at 10 psi, took it about a 45-60 sec to get there.

the code are 12 only.

Also the car is starting now. have not tried to drive it yet.

The fuel pump is only powered for 2 seconds when the key is first turned on so to get an accurate reading you either have to cycle the key on multiple times or check it with the engine running or cranking.

If you really can't get more than 10 PSI, then you have a serious fuel pressure problem, likely a bad pump.

The spec for that car is 40.5 to 47.0 psi

That was with the engine running, will be checking at the fuel filter next to rule that out as a part of the problem.

No, it's not the fuel filter. A plugged filter can ruin the pump but it cannot be the sole cause of low pressure.

To confirm a bad fuel pump you actually have to confirm full power and ground arriving at the pump but you likely need a new pump. I would always include a new filter to protect the new pump.

After replacing the fuel pump the car ran great for about three weeks.

Are you saying it is still running great or you have another problem?

Yes due to many other problems motor and transmission were replaced.

See other post for more information on that part of the job.

All the information given here and other tread helped get to the car running and on the road.
