Question about 1988 Chevrolet G30
A new engine was dropped in a Chevy Step Van...
The person that put it wired the plugs wrong, so I changed them and got the truck started...
As soon as I parked it outside, I rev'ed the engine a couple of times and it died and will no longer start.
It has a TBI and both injectors are spitting gas into the throttle body, but there is no spark at all from either the coil or the distributor.
I replaced the coil, and still nothing. It is still spitting out gas, but there is no spark from anything.
There is over 12v going into the coil and distributor as well.
Could it be the ICM as well?
Have you put a spark plug fire tester on the plug wire and verified there is no fire at the plugs or do you just figure because it is getting gas if must be an issue with the fire. I ask this because the age of the truck it may have a plugged converter or muffler on the truck and if one of them are plugged it won't allow the engine to pull the fuel into the cylinders and fire. You can remove the 02 sensor ahead of the cat and the truck will start if one of them is plugged up. The truck will not run well but it will start and run ruff. Hope this helps.

Take off the distributor cap. Check the star wheel that is splined to the distributor shaft that the pick-up coil uses. Make sure this wheel is not loose on the distributor shaft. It is right above the pick-up. If it is loose, replace the distributor. This is a common problem. If it needs one, all the part stores stock the distributor.

You need power on both sides of the coil with key on engine off. With test light on neg side of coil you should get flashing light with engine cranking. No flashing indicates no trigger from ign module. No flashing can also mean the pick-up is faulty. To check pick-up dissconnect from module and use analoge meter set on ohms.Check meter movement during crank. If o/k check rotor for burn through.and change module.

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.
