1994 GMC 1500 fuel injection problems
I didn't know where to post this so i figured this was as good as place as any.... My 1994 gmc c1500 is not getting enough fuel and i'm wondering what the reason is? Where is the best place to start looking for problems? or maybe it's just dirty injectors and some injector cleaner could solve it?

When i get on the throttle there is a delay and when i'm at higher speeds like 50 or so when i try to speed up some it kind of stutters. Also when i hold a constant high speed it will.

Could also be a cap, rotor, or wire issue. Those tiny caps are prone to crossfire if the wires are marginal.....

Had a similar issue with my 95 suburban, after replacing fuel filter, pouring in a couple can injector cleaners, and replacing the fuel pump, (twice) found out it was the fuel pressure regulator. :shock:
They make a rebuild kit for it too, $40 bucks autozone.
Goodluck, Cp
