Hey guys,
For the first time in 5 years of owning my Tahoe, it has finally left me stranded! The ECM 1 fuse instantly pops every time I turn the ignition on... I was hoping for a wire on an exhaust manifold grounded out...sadly, that was not the case. I unplugged the computer and it still popped the fuse...I unplugged a few sensors on that circuit and it still popped the fuse...
Last, I unplugged the main injector harness directly on top of the engine...the fuse would not blow with that harness unplugged. Is my injector assembly bad...? I replaced it a few years ago with the upgraded Delphi MFI version...
It's weird, I drove it to a friends house...it sat for about an hour, then it wouldn't start when I tried leaving.
Any help is greatly appreciated!
