Engine cranks will not start

[JOHNMAKI]

1989 1500 4X4 with a 5.7 engine. Engine cranks over but there is no signal to the fuel injectors. I thought it was the computer ground at the water neck but that is good. It will start when you don't need it to start. Very erattic. I am thinking it has something to do with the computer or the grounding of the computer. Any help with be appreciated. Thank you.

Clean out that throttle body.

Check your fuel filter/pump. Is it getting fire? Check your ignition components.

If I remember right you can put a jumper wire from the "a" terminal to the "b" terminal on your aldl port and than the check engine light will flash every time the ecm recives a signal to fire the injectors from the pick up in the distributor. Hope this helps

I might be pissin' into the wind here, but maybe your ignition module.
