1991 Trooper 2.6 / 5spd 155k mi
So Ive had this truck for about 40k miles. Never once a problem
ran out of gas this morning. Not completely though, it would stumble on full throttle. I made it to the gas station and threw some gas in there and it wouldnt start.
I messed with it for a while and used some starting fluid, etc. I can get it to fire and if I pump it... it will stay running. I cannot hold it at any RPM as it will steadily slow down and die. But if I pump that effer, it will stay going.
I replaced the fuel filter just now assuming that I had sucked some crap out of the tank and clogged it. Nothing. Still runs about the same. I cant drive it.
I dont think it could be injectors because it will run and it sounds good when I rev it... but when the revving stops, so does the engine.
w.t.f.??????

any ideas?

 

This could be one of many things and us on Yahoo cant help you by thinking what it could be.

 

are you effing serious?

 

My 91 done the same thing and I ended up replacing the fuel pump, It quit completely. Was running good until it ran out of gas and then would never restart until I pulled the pump and replaced it.
