Asked by Jpena41 Jul 18, 2014 at 06:52 PM about the 1994 GMC Jimmy 4 Dr SLT SUV

Question type: Maintenance & Repair

It will start idle with no problums I can
give it some gas an drive 2 feet befor
it looses power, I think its the
regulator or fuel injectors were the
engine is flooding or something cuz
the fuel filters look real new an it has a
new fuel pump so it has to be the
injectors or the regulator. Once it
looses power it takes for ever to start
but it cranks and everything fine, once
it dose start if it starts again it will be
alot shorter than the 1st time an gose
off right then an there. Engine light is
on but cant take it safely to get a
dignostic test an the gas gaude dont
work so I have no idea how much I
have in there main thing is it wont
actually drive or stay on an there is no
miss fires it had a tuen up. I need
help???

well, you can check the codes with nothing more than a paper clip and counting flashes. Google how to check gm obd1 codes. Also runing a fuel pressure test and leakdown test would help rule out or pinpoint possibilities, i'm also thinking vacuum leak, or maybe a tps issue. Get the codes then go from there
