I have a 1998 silverado with a 5.7. It will run with starter fluid, but not on it own. I replaced the fuel pump, fuel filter, fuel pressure regulator, and cam sensor. The injectors have 12 ohms. And when i try to start it it has 12 volts at the plug, but it does not pluses ir just keep 12 volts the hole time. I dont have any security light on. I was thing it was the pcm but i dont wont to replace it if that not it. ?????

 

ignition control module?

 

If it was the ignition control module would it still get fire?

 

I have between 60 and 65 psi of fuel pressure

 

Sounds to me like the ecm

 

that what i meant ecm not pcm. I cant see anything else it could be in the diagram but the ecm.

 

when my icm dies on my 93 I have spark but no injectors, can run motor pouring gas down throttle body. On my 3rd one. 98 may be a different beast

 

i got a ecm coming in the mail it should be here Thursday. But if that doesn't fix the problem ill look into the icm. Thanks for your help.

 

Did you ever figure out your problem. I have a 2000 GMC K2500 that is having this exact same issue. I have tried 3 ECUs and replaced everything fuel system and spark. Its as if the injectors are not firing.
