First test. Turn off everything in the car so it will be wuiet. Then turn the key to ON while you listen very carefully for the fuel pump to run for 5 seconds. The pump is in the tank.
Report results. You need 40 psi at the injectors before you crank the engine. Then, when the computer operates the injectors to open the "valve" momentarily, fuel will spray into the manifold, like it should.

Check the fuses for the pump.

Car wont start

Try a little starting fluid in the intake and see if it runs a few seconds. If it does, it could be low fuel pressure or an injector problem. Maybe they aren't pulsing.
You have voltage to the injectors; now check the ground circuit: Use a test light and clip the lead to the POSITIVE post of battery. Put the probe into the ground terminal on an injector connector, and have someone crank the car over. If the test light is blinking, the ground circuit is good. When it blinks, that is when the computer is grounding the circuit for injector pulse to occur.

My dodge stratus wont start it will turn over but wont start

Listen for the fuel pump when you first turn on the key to the run position. If you hear it then spray a small amount of starting fluid in air intake while someone tries to start it if the engine fires then most likely a Crank Position Sensor. The CPS controls your injectors.

Is the security light lit on the instrument cluster ? Injectors firing ? Spray carburetor cleaner through the throttle plate an see if starts then . If it starts an runs for a second it's not getting any fuel . How do you know it's getting gas ? Did you hook up a fuel pressure gauge ? Hook up a scanner an check an check data parameters ?

My 99 pontiac grand am wont idle or start i changed head gasket and intake manifold gaskets

First thing I would do is a compression test on cylinders, then fuel pressure test. Make sure your starter relay is good. If it is cranking over but not firing could be fuel relay, fuel pump, and could be as simple as a vapor lock. Spray some starter fluid in the intake, if it fires up for a couple seconds, then tells you not getting fuel, and this narrows down the search to the fuel pump relay, fuel pump.

Now your statement is YOUR CAR wont start or idle, as you can tell that is two different things. Which one is it, wont start at all? or starts then dies because it wont idle?If it wont start, then check the things I just advised, if it wont idle, then that could be plugs,coils,idle arm, fuel filter possibly clogged. List goes on and on. Need to know little more detail of what exactly it is doing, and what you have already checked or tried for me to dissect it down more direct with trouble shooting. I can help you for sure, just little more info needed, or you can go through the list I just said and it will I am sure fix problem once you check and repair or replace as you come across that problem area that is not functioning proper. Thanks Mike

1998 expedition wont start

first of all its not good to spray starting fluid into the intake,its got a plastic "LOWER"intake and it can blow apart and **** too much air through it.Next reset the computer and it can be done by un-hooking the battery cable for a few minutes and if this works and runs for a while and does this again,then reset the computer again.If it does it again then maybe replace the computer..Then also check the fuel pump,it may sound like its working but it could have gotten hot and the plastic gear on the end may not be pushing fuel through when it runs for a while.

I would check your intake gasket. Get your self ome carb cleaner in a spray form/can and perfrom this test. Run the car and spray the carb cleaner on your intake gasket which is right by your injectors. So pretty nuch spray it at the injector rail and listen fot change in idle, If the idle changes, the intake gasket is torn and you are running lean, because of a vaccum leak. Common problem on your model car. Perform test and let me know what you find.
