If gas is getting to the fuel rail, it is getting to injectors. If fuel pressure is good, probably the injector circuit is not working. With a test light you can check the injector circuit. Post back for further help. What year and make is the car?

SOURCE: car starts and dies only stays running as long as

off hand I'd suggest a concentrated injector cleaner (one you'd have to spray in the throttle body), if that seems to help, then add some to the gas tank at next fill-up to further clean and, on occasion (maybe at every other oil change), there-after to help prevent it gumming up again

I change the motor in my 96 dodge 1500 now it won't start acts like its not getting gas


You would need a voltmeter to diagnose the fuel pump circuit. Or you could put a fuel pressure gauge on the shrader valve test port to check fuel pressure. Just turning the key to on should cause the pump to run for 2 seconds, putting pressure in the lines and at the fuel rail and injectors. Now the pressure should show pretty high, often over 50 psi for multi port injection. Can you hear the hum or buzz of the pump running for 2 seconds with key turned to on? One test is to spray some starting fluid into the throttle (air) intake and see if engine fires on that. If it tries to run then, well sure enough it wasn't getting gas. Now you'll have to check the fuel pump and circuit.

Will not start


Gas, air, compression, and spark is all the cylinders need for the engine to run. No start is usually gas or spark related. Here's the fuel check on fuel injected cars. Turning the key to on will start the pump for 2 or 3 seconds to pressurize the system. When the engine is cranking over the computer turns on the fuel pump relay again, so the pump will be on. And stays on after engine is running to keep high pressure against the fuel injectors. The computer times the injector pulse to spray gas into the intake or into the cylinder at the right time.
So if you have a no start, to check for gas, listen for the pump- a distinctive hum or buzz from the tank, check the fuel pump fuse, see if you can feel or hear the fuel pump relay click when someone turns the key to on. (Did you remember to check if the tank has gas?). Finally, you would have to check for power on the fuel pump wire at the tank connector, while someone holds the key in start. If you have power there, it's likely you need a new fuel pump. If the pump is working, well and good, but keep in the back of your mind that a weak pump that puts out low pressure can cause hard starting problems and poor running. At any rate, if you have gas up to the fuel rail, the only other thing between there and the cylinders is the injectors. Are they working? A quick check would be to remove a spark plug or two after cranking the engine over a few seconds. If they are wet with gas, the injectors are injecting. Hope I've helped you out some. I know some people who say to spray some starting fluid into the air intake to check if you have a gas problem with starting- I've done it myself. But I've learned it's better to use carburetor cleaner spray instead, it burns cleaner and something about the potentially harmful effects of starting fluid, well. good luck.

92 lumina not starting


Possibly a fuel regulator or injectors? it seems that there is insufficient fuel going into the combustion chamber. Take the fuel line off at the fuel rail and stick your finger over the hose, now get a friend to initiate the fuel pump by turning the key to on for a split second, if you cant stop fuel from ******* out from where you have your finger you know that the pressure is ok up to the fuel rail, put the fuel line back on then move onto your pressure regulator etc.

Why won't my 1997 Saturn SL start?


you have spark at the plugs ..thats something

spray stay you mug
into the throttle body see if the motor will cough

tank needs draining and have fresh fuel
fuel pump has a filter and fuel relay

crack the fuel line connection to the rail to see if there is fuel reaching the rail and correct pressure

if sitting 6 years.. not being run regularly
do a compression test
lifters may be stuck
rings may have lost tension

2002 chevy Blazer hard starting did change fuel pressure regulator and fuel filter when we spray starting fluid in throttle body it will start.


replace the fuel injectors, that is the likely cause......

to test the injector, take the power clip off the top of the injector, take one wire and ground it to the body of the car, and another form the battery, to the other post on the injector, if you do not hear a pulsing sound coming from the injector it is bad, if you do, then you have a wiring problem.

Fuel isnt coming out hte injectors


ok when you turn the key on, you hear the buzzing sound in the tank? if you spray starting fluid into air intake, will the engine fire? there should be a fuel pressure port under hood on fuel rail i believe. if this is vortec style engine, injector assy under intake is possible. somewhat common. pull oil dipstick and smell for fuel. that would indicate maybe the pressure regulator has let go. ck for spark as well, just to be sure youre on the right track.
