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.

Where is the fuel regulator located on a 1988 tbi


Sits inside the throttle body, you would have to open to install regulator. Also check your fuel filter make sure it's not clog, fuel filter is under truck on fram rail, while your there do a fuel pressure test, with a fuel pressure tester, should have 13psi.

I have an 1988 chev 350 5.7 liter , my injectors will not work, there is fuel getting to the tbi, but somthing is telling them not to open, it was running bad now no fuel, i unpluged the map sensor. and...


you should have over 9psi while cranking with injectors working to start. if there is not enough presure it will not start. The computer tells the injectors to open, it actually controls the ground side of the injectors with power side always hot. the computer NEEDs the map sensor or it will not start, it needs crank and cam location sensors from the distributor, the TPS, etc. Plug all sensors in, check fuel presure, clear codes and start over, checking codes to determine what isn't working.

Fuel not getting to carborator.


The filter is external. Located on the passenger side frame rail, about 4-5 ft from the tank. round, metal (or if previously replaced-- might be plastic). Are you sure you have a carb? 1988 models were throttle body type fuel injection. If it is TBI, you may not be getting power to the internal fuel pump. Are you seeing a fault code (the check engine light flashing)?

Low power when accelerating


I thought the filter might be the issue here, on carb cars the engine tends to stall out with a plugged filter.
