Your injectors may be shot ... That might explain the code. As horrible as this is to ask, you seem pretty handy with your tools, do you by chance have a carburetor, perhaps a quadrajet or whatnaught, to hook up just for a second to see if your ECU/fuel injection system is FUBAR'd?

Get a hanger cut the long part of the hanger, bent the very tip about an 1/8" of an inch at 90 deg, the tip you bent hit it with a hammer so that it's some what flat, turn the window handle so that it's pointing down, push back on the door panel, in back of the window handle there will be a small clip, with the hanger pull the clip up and remove it , the handle will slide off on.

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.

Either not enough air or fuel. Check the air filter and gas filter. Also could be the exhaust system Catalytic converter clogged. No air out, no air in.

If you replaced everything back to the guage itself, then it has to be the guage itself. I would try getting a replacement instrument cluster at a salvage yard.

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.

Run pressure test on your fuel injectors. Fuel pump might not be suppling enough fuel line pressure.

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
