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.
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.
