Gmc K 1500 4x4 Doesnt Stay Running

[Loudpipes]

(95 gmc k1500 4x4, reg cab short bed.)

 

I was driving one night, then it seemed like it was losing power, so i was feathering the gas pedal, and it kept doing so, so i pulled into a parking lot and it stalled. The trucks been doin that ever since, i cant drive it.

 

Any suggestions?

sumthin similar happened to me, check the gas tank or sumthing to do with it.

[ottovanbismarckq80]

do u usualy let ur fuel run low? if so then definitly the gas tank, dirt piling up etc.

Easiest thing is to replace your fuel filter. Next would be to replace your fuel pump. Odds are it's one of those.

Had an issue close to that one as well, I started at the fuel tank, then ended up at the dist. cap and button. Funny thing is, it was the last thing I tried that fixed it. ( it always is ). I have continued to run Lucas injector cleaner through the system at every fill up since. I know it was the cap and button, however, your fuel system can always use a good cleaning!

 

Good Luck!

well, i changed the dist. cap and rotar, that wasnt it. fuel filter is next, if not, fuel pump.

its probably just a dirty fuel filter..

Do you have any codes set ( check engine light ) ? The codes may narrow your problem search.

Do you have/can you get a fuel pressure gauge? When the truck cuts off, check your pressure at the fuel rail.

[Loudpipes]

changed the fuel filter, didnt work.

 

Going to check the fuel pressure soon.

Have you checked for any vacuum leak's?

I'd guess its your fuel pump.With the in tank pumps you need to keep at least a 1/4 tank in it because the fuel is what keeps the fuel pump cool run it low to many times and it will take a crap on ya.

Quick check is have a helper turn the key on while you lay down next to the tank holding your hand on it, listening/feeling for the pump should come on for about 8-10 seconds then shut off.
