I have a 99 chevy s10 zr2 that will crank but wont start

SOURCE: vehicle just keeps cranking wont start.

Make sure that your fuel presure is up to at least 60 psi if not that could be your problem. If not, make sure you are getting spark, if not could be your Crank sensor or ingniton module ECM. Usually if your Engine control module wouldn't be bad because of your fuel pump is working, but may not be putting out the proper pressure for the fuel system. Fuel Pumps are a Problem with that year..

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

If your timing belt broke, then it is possible that the valves in your engine got bent, which won't allow the cylinders to pressurize the fuel/air mixture, and it will let all of the mix to flow freely into the intake/exhaust manifold. This can be checked with a pressure tester that is threaded into the spark plug opening. A mechanic should have one, or you can probably find one at an auto parts store.

I had a simular problem. I had bad plug/coil wires. The foil insulation from the engine cover would draw the voltage from the wires.

SOURCE: hello,

try checking the fuel injection module out, ( "spider injection module"). My 2000 blazer did the same thing, fouled out the plugs and all, i hooked the fuel pressure gauge up and had good fuel pressure, just no start. I took it to the shop and they found the injection module to be the culprit. you'll need to replace the plugs if it was the problem since you cranked and cranked it over.
