What exactly happens when you start the engine, does it stumble and die or just not run at all?

If the former, what happens when you depress the gas pedal while cranking/just starting?

If i try to start it as is it WILL start but will die in about 5 seconds. If I gas it quick enough after it starts i can keep it running for about 10 seconds but also at that time if i were to relase the gas it would die immidetaly.

If you supply auxiliary fuel (starting fluid for example), are you able to keep the engine running longer that way or no change?

No not yet. I just had that same question asked about 5 minutes ago. Im going to go to the store and get some I just dont know where to spray it in my truck . Would i pull my air filter assembly off using the wingnut and spray into what looks like a carburetor?
Expert:  Doug replied 1 year ago.

If you have a carb model (2.6), then yes. Just do not over-do it as it can fire back out at you.

If you have a fuel injected model (2.4, 3.0) then you would want to temporarily pull the intake hose off, spray in, then reinstall and try. If your can has a nozzle straw, you can slide it in beside the hose to make it easier to repeat sprays. Of course it helps to have two people available for this check since we want to try to keep it running longer, proving a fuel related problem is afoot.

I see. How about i get back up with you tomorrow when i have the equipment and i will find someone to help . I believe i know where this is going . I helped a friend do the same thing and he ended up saying his fuel pump went bad . So i see how it would be easier with 2 . I will messege you tomorrow so we can wrap this up and so I can see what i am doing.
