Chek the fuel regalater on the back of the fuel rail. it has a rubber hose to it.and even if you can here the fuel pump dosent mean it isnt weak.

What would make a not start unless I pour gas into intake


Hi Clyde:
Since you mention "gas rail" I'm assuming fuel injected.
I'd check the fuel pressure in the rail. Should be around 40 PSI.
If pressure is OK then injectors not working. Time to check cps.
You know the spark side is OK since it will run.

I have a 97 dodge stratus. It won't start. Tried


Make sure it's getting fuel. Try using some ether or starting fluid. If it rumbles to life but doesn't stay running then there's a problem with the fuel delivery system. i.e.... Fuel pump, clogged filter, pressure regulator.... If the ether doesn't change the results you are getting now then it's a fire or sensor problem. Ignition coil, relays, sensors not signaling, PCM... I wish you luck. Let us know how it turns out

Starting issues


So you know it is not getting fuel thru the injectors.
Have you checked fuel pressure at the rail, and do you know if the pump is running when you turn the key on ?

1985 grand Marquis acts like not getting fuel to start but if I pour gas directly into throttle body starts right up and runs what could be problem


Runs on the gas you pour in, or keeps running until you turn the key off ???
If the fuel pump relay fails, you would have to crank the engine until you get oil pressure to provide power to the fuel pump.
Do the injectors spray when you are cranking it ? Have you checked fuel pressure when the key is turned to start ?

1994 Chevrolet Lumina 3.1 will not start - after starting with ether runs fine.... 1994 Lumina 3.1 will not start - cranks but won't start. While cranking shoot ether into intake - starts...


Had friend put OBD diagnostics to it and error code indicated fuel pump ????? No code indicates replacing any part . Indicates testing ! pressure and flow testing , voltage drop testing the electrical circuit etc... There is a check valve in the fuel pump assembly that is suppose to keep pressure in the fuel lines an fuel rail . When the check valve goes bad allows fuel to drain back into the tank. Try turn the key on an off a few times to build up pressure . The PCM energizes the fuel pump relay for two seconds at key on .

89 dodge d159 318 will not start unless spay ether or gas into carb, starts immediately then burns off ether an stalls. not getting fuel to TBI


sound like you have either a clogged fuel filter or a bad fuel pump
start with the fuel filter first keep it simple first
if that don't work for you then pull your fuel line off and cycle the key and see if the pump is putting out fuel
if you don't get fuel then change the fuel pump
hope I could help
leave some feedback if you could
good luck

I have a 1992 camaro RS 305 with 5 speed. It will turn over but won't start, if you pour gas in throttle body it will fire right up and run like it should. I put in new fuel pump, new ECU, new TPS, still...


If you turn the key to the on position and you hear the fuel pump run, does it run for longer then 5 seconds? If so then you are going to need to look at your fuel filter, if it stays running then you are going to need to look at your fuel regulator. You can also go to Auto Zone and buy a fuel pressure test kit or rent one, and check your fuel pressure on the fuel rails. Check for spark also, if you are low on spark then you are not going to fire, unless you dump more fuel then you need to into the throttle body.

It starts & then immediatly shuts off..... but will keep running if i spray ether into the carb not a plugged injector, not a fuel pump, and the rails are getting fuel


check the fuel pressure in the rails. There may be a low pressure that will not allow the spray to be misted enough. It could be a clogged fuel filter also.
