Hi Nsilguero,

I apologize for the delay in responding.

From your description, I'm leaning toward a timing chain problem, first stretching, then skipping and finally breaking.

If you're getting voltage to the coil and still getting no spark, there is a test I'd like you to try.

Take off the distributor cap and have someone turn the engine over while you eyeball the rotor. Is it spinning?

This going to take some back and forth interaction. Comment me back with the results. We will proceed from there.

SOURCE: I have a 1991 chevy truck, I am getting no spark.

Possibly ignition switch, Power (12 volts) going to distributor goes through ignition switch.If you read voltage on the primary side of the coil, with the ignition key on, can you read 12 volts, maybe a little higher? If not, that's pointing to a problem. Good luck.

SOURCE: 1987 chevy s10 2.5l tbi will not start. changed

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.

More than likely it's the distributor. They have a tendency to build up corrosion and rust and have personally went through the same situation three weeks ago on a suburban. Check to see if you are getting spark from the distributor first. Have the ecm in the distributor checked at Oriellys for free. It's under the rotor and has two 8mm head bolts with wires plugged in at each end.
