That would be a good place to start -replace the filter-then if not better do the pump-Denny

First off you can test the fuel pump 2 ways
1.have a assistant turn on the ign to on while you listen for the pump to run at the gas cap (gas cap off).
2.find the valve on the fuel rail looks like a a/c or valve stem,take the cap off and press the needle and if fuel comes out then it's not the fuel pump.

But from a lot of EXPERIANCE on dodge engines the stalling and restarting issue is ignition related i.e crank or cam sensor which will throw a diagnostic code of engine misfire xxx cylinders.

So If its one of those sensors then you will not have any spark,and staring fluids will not fire the engine.
As for the headlights flickering they get there power through a relay straight from the battery,so I would look at the relays under the hood and find the one for the headlights and swap it out with the horn relay as most of the relays will have the same numbers.

The crank sensor is about 70.00 and the cam sensor is about 50.
depending on where you get them (dealer or aftermarket)
the cam sensor is the round plastic thing under the dist cap,and the crank sensor is on the pass side under the head into the top of the transmission bell housing and it's a 2hr job to change because of it's location is really hard to get to.
Hint -take the breather off and place a rag over the intake and a board from the radiator core support to the intake to lay on,it has 2 10mm bolts and the wiring harness unplugs from underneath.

the auto shutdown relay is usually right next to the fuel pump relay and there will be a starter relay and fan relay also.

I have a 1995 Dodge Stratus and I had the same problems last winter it turned out to be the main brain the ECU as they call it It costas about 1200 dollars new but i scored mine from a junk yard for 10 bucks and my car hasnt done it since. They very well may be your problem because i have the same engine in my car its just a smaller body style. look on the net for spaldings used car parts u can look up parts and they usually sell ecus for 75 to a 100 dollars.

91 Lumina crank no start.

If cleaning the injectors got it running and not it won't start I'd look at something contaminating the injectors, try recleaning again and see if it starts, if it does clean the fuel system

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 .

Car starts but then dies

Perhaps try a fuel pressure tester to see if it's holding steady pressure when this occurs. This sounds like the symptoms of a failing pump however, don't just change the pump. Confirm it by monitoring the pressure. I've seen some guys tape the pressure gauge to the windshield so they can see it.

1991 Dodge Dynasty LE car will suddenly die while driving. If I pull off the road, turn the ignition off and restart it- will start but when I put it back in gear the engine stalls again. After five or ten...

Sounds like you are having a fuel problem with the fuel filter. If you have not had your car serviced in quite awhile i would do so. At least change the fuel filter and check the air filter as well. Hope thias will help you.

91 honda civic dx. Starts, runs for a few seconds then stalls

Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.

Fuel system problem

Could be the fuel pump yes. Carburated is it? Maybe it's gummed up.
