Hi I have a 1990 k5 blazer with a 92 350 in it. I was going into town and it just stalled would not start unless I sprayed starting fuild into the TB. So I checked online and someone said to check to see if there was power to the injectors so I did and there is no power how do I find where the problem is. Any help would be great thanks

Frequently, vehicles will only run with starting fluid, if the Ignition Control Module (ICM) is bad.
