i doubt its a fuse. make sure all cylinder have good spark. try and run some seafoam through the gas tank and i would look at the timing - im not sure how you know the timing didnt skip but that sounds like your problem.

It sounds like that the security system has encountered a problem...Did you notice a light coming on the dash saying security? Your ignition ,all though no chip in key,references to a security module...what this does is tell the computer that the same key is being used to start vehicle...The condition that would come from this problem would be a crank with a know start condition....the security system actually shuts down the injectors if reference signal isnt recognized.POST IF THIS IS THE CONDITION YOU ARE EXPERIENCING>>>

Fix rough idle and stalling on 1986 S10 blazer.only keeps running if pumping gas pedal. was running good and all of a sudden started dying out.


I would start by changing the fuel filter. Run some injector cleaner through it. And check for more of those rotten lines. You can check by spraying a little starting fluid around the vacuum lines. Be careful though. Its flammable. But the engine should speed up if you have a leak.

1988 2.5E s10 no fuel


you mean,cranks ok, but will not start and no fuel , right>?
s10 no fuel. 1988 ( S10 blazer )
please do say , what that means.
1: car cranks and will not start. so must be out of fuel?
(over 50 causes, or better is 10 or less tests (ask)
2: same, and fuel pressure is 0 psi (spec.9-13). gauged.?
3: fuel dribble test?
4: sparks good so tired test fuel and it ran on test fuel ok? proving
loss of fueling>?
5: injector dead cranking, (eyeballs)

which was it?

1988 cars in the USA are BIG TIME TRANSITION year.
we went from CARBS to EFI.
2.5L (what is E)?
gear cam, roller HLA lifters.
your car, USA , is TBI engine,
TBI started on THIS car in 1985 (1/2 and 1/2)
Throttle body injection
an on all TBI engines, one can see it inject with eyes.
does it?
if not it can be the following things.
1: no fuel pressure, 9-13pis.
2: ECU is cutting fuel. Pressure good cranking.
2a: ECU is sending error for bad crank/cam sensors, and cuts fuel.
2b: ECU sees rpm or tacho line dead.
2c. ECU sees TPS sensor output as 4v or more cranking, this cuts all fuel.
3: if ECU is happy, it sends 12vcd to the pump, cranking.
all tests must be dont cranking or chase tail.
