    When you try to start the truck does it run for 1 or 2 seconds then die as if it were out of gas? If so check your crank position sensor.

What is your Fuel Pressure? Did you put the fuel filter on with the arrow pointing towards the engine? If so, then check to see if your fuel injectors are working. You will need to get a noid light set from your local parts store and plug them in to each individual fuel injector connector and get someone to turn the engine over while you watch the light. it should blink on and off. If not then you have a short in the wire or possibly a fuse blown. check the fuse compartment ( usually under the dash or under the hood) and find the fuel injector fuse and see if it is blown. if it is then something caused it to blow like a spike in amperage or a short to ground. check for broken wires on the fuel injector connectors and make sure they are securely connected. If it does blink on and off then they could be clogged, but normally if one is clogged or even not functioning, the truck will still start, it will just run rough. So im assuming something is not letting the fuel injectors pulse or your fuel pressure is too low to start an engine.

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 ?

It will start run for a few seconds then die,u can pour gas in throttle body and it will run as long as your pouring gas in it,ive changed fuel filter.I checked fuel pressure and it is fine,60 psi.


Have you checked to see if the injectors are getting a signal? The best way is to hook a noid light to the injector wire harness and crank the engine.

99 tahoe,changed fuel filter,and poured some gas in the throttle body and it will start.


i am assuming that this vehicle will not start without the gas poured into the throttle body? If so then there is a fuel dilevery problem which can be coming from injectors that are not firing due to clogged injectors or a malfunctioning injection pulse. or clogged fuel delivery system which is most probaly not the case due to you changing the fuel filter, or a bad fuel pump. you have some testing ahead of you.

Fuel supply


sounds like there is no power to the fuel pump while cranking. check the oil pressure sender this helps the fuel pump run under cranking

Fuel Filter Changed


What happens when you remove air intake from throttle body & spray a little wd-40 in to the throttle body, and try to start? If it starts and runs temporarily, you've still got a fuel delivery problem.That coffee color worries me, like maybe your fuel lines etc are plugging up with rust etc, from inside tank. Have you added any fuel system cleaner to gas lately?
