Hello, I recently got stranded on the side of the road where my efi fuse kept blowing on my 1990 22re pickup. To get home I threw a 30 amp fuse in the 15 amp slot and used a paper clip to jump the efi relay terminals. By a miracle I made it the 5-minute drive home and the truck shut off right when I got home. I opened the hood and saw the paper clip had melted away and I assume this cut power to everything connected to the EFI circuit. Regardless, I got everything in the fuse box cleaned up and replaced my fuseable link for an inline fuse while in there. Also, I found the culprit which was my O2 sensor cable rubbing agains the drive shaft and shorting out leading to the efi fuse blowing, I wish I had looked under the truck in the moment but here I am. Regardless after rewiring that, I checked continuity on the white and red efi power cable, and we are no longer grounding/shorting out. However, I went to crank it up and it lit up like normal with battery, parking brake, seat belt, and check engine lights lighting up. But it doesn't crank up. And now when I turn the key the check engine light is not lighting up anymore. So my current thought is the ECU may be shot, is there a way to ohm check the ECU? I opened up and all soldered connections looks good, making me question if the ECU is at fault.
