95 S10 4x4 4.3L ECM Bat Fuse Blows

[dale915]

I have a 95 S10 4x4 4.3L, that will blow the ECM bat fuse only when the truck is in gear and I give it to much gas (goose it a little). When its out of gear I can goose the heck out of it and rev the engine to high rpm's and the fuse won't blow. I also had a repair shop run a diagnostic on it and it shows everything is fine. I've changed the fuel pump wiring harness and ECM. Any thoughts about what it could be.

you will have to check wiring from fuse panel to ecm. i suspect wiring is chaffed where it crosses the engine from drivers side to passenger side front fender........
