Pump is in fuel tank. It is a miserable job, do not attempt unless you are experienced at frustration. The fuel lines will likely be seized as well as the tank straps. Also the sending unit will be rusted together and will have to be replaced, the tank likely will be rusted under straps and will be no good to reinstall.

91 Lumina won't stay running; see lots of same question for same car but no problem solvers....Please help.


On electronic fuel injection pumping an pumping an pumping the gas pedal does nothing without the engine running ! Pushing the gas pedal to the floor will cause the PCM - engine computer to go into clear flood mode .

You have some very interesting ideas here , but not really how it works or is !

The vehicle will go into closed loop fuel control when the engine coolant temp reaches a definded temp an the O2 sensor get hot.

She would run for a couple minutes and die which is open loop when running, closed loop is when the sensors kick and it would die. Pulled spark plugs, they were black meaning no spark. Can only be 2

Black spark plugs indecate a rich condition , over fueled , wet spark plugs indecate no spark .

I have a 91 chevry lumina 3.1 v6 i put and new fuel pump and filter and relay and check the coils they are fine i can start it it will run for about 5 mins and stops then restart fine and dose it again...


You've done well by ruling out the most likely things first. You need to next check the condition of the "ignition module". When this module starts to heat up, if bad, it will cause the engine to shut down rather quickly.
