'96 Chevy Silverado C1500, 2wd V8 5.0SFI. Truck stalled going down rode, got a code P0102. Fixed vac leak now no code but won't fire when starting. Engine turns but won't fire. MAP sensor new, MAF sensor good, starter coil good, ditributor cap & rotor button new, plugs & wires new, good fuel pressure, battery new, got it to fire with starter fluid but got a funny smell like burnt plastic, metal, n burnt marsh mallows, no vac leaks, no manifold leaks, n still won't start. What else should I do?

SOURCE: Won't Start.

These trucks have a problem with the catalytic convertor blocking the exhaust causing a no start condition, the three things you need to start fuel, spark and air. Try disconnecting exhaust in front of cat.

It sounds like they have got the distributor out of time. You will need to adjust the distributor. That is what it sounds like.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

i do believe that's what it is if it will not let get a diagnostic or if it will not let you access the computer the computer is bad.

REPLACED IDLE AIR YOU HAVE TO ADJUST ITS DIMENSION. MEASURE FROM THE TIP OF PINTLE TO THE MOUNTING FLANGE.YOUR DISTANCE HAS TO BE 1 1/8 INCH.IF NOT ADJUST PINTLE BY PRESSING IT 1 1/8 INCH. YOU NEED TO RESET IDLE BY CYCLE THE IGNITION KEY ON FOR TEN SECONDS THEN OFF FOR TEN SECONDS TO RESET THE VALVE.START THE ENGINE ALLOW IT TO IDLE FOR FIVE MINUTES TURN THE ENGINE OFF FOR THIRTY SECONDS THEN START THE ENGINE AGAIN AND CHECK THE IDLE OPERATION.
