CHEVROLET S-10 ENGINE PROBLEM

1997 Chevrolet S-10 • 300,000 miles

The grey wire which is hot wire that goes to fuel pump, is hot all the time even the key is off. I unplug every relay I can find but still on, engine freshly overhaul trying to start it. No fire at coil also.

Check the oil sender switch, that is a bypass in case of relay failure. It may be shorted.
