Question about 1990 Chevrolet Lumina

1 Answer

1990 chevy lumina 3.1 MPFI and will not start?

The car will start if you hold the gas have way down and hold it and you have to keep pumping the gas to keep it runing sometimes. I replaced the head gaskets and thought that maybe my problem but its not. I also used it as a snow plow for two days ( snow was packed in the engin pay up to the exhaust and i had to jack it up and put a heater under to defrost it). If any one has any answers i thank you very very very much.

How do you remove the fuel pump on a 1990 Chevy Lumina APV?


The fuel pump is in the gas tank. Drive off or siphon out as much gas as you can. You will need to remove the filler hose. Drop the tank and remove the fuel lines on the top of the tank, Turn the ring counter clock wise that holds the siphon and pump in. Once the ring is loose, lift the the siphon and pump assembly out of the tank. The pump is on the bottom of the siphon. Replace, then reverse the process.

1990 chevy lumina, idling problem...stalling...too rich


Stalling and running rich. I have seen this before on a Camero. The fuel pump was weak. Not making enough pressure. This caused the fuel injector to DRIP gas instead of SPRAY gas. This caused the fuel to flow into the cylinder in a liquid form, and it did not burn well. We put in a new fuel pump and the car came to life. Good luck.

I have a 1990 chevy lumina runs great until you turn it off and restart it acts like its not getting gas


Hard starting? Try holding accelerator to floor until it catches then let off immediately, so as not to over-rev engine. (As it was done for a flooded situation with carburetor.) You may be getting leak-by on one or more injectors, causing it to act like a flooded situation.
