A couple years ago my truck just turned off while I was going down the interstate. When this happened I saw the EFI fuse blown, and incorrectly assumed that the fuel pump was overloading. I was trying to get the truck off the highway and bypassed the fuse with a wire (dont EVER do this!). This blew out a huge resistor in the ECM, and I was able to pull another from a junkyard thankfully.

Come to find the (+) wire to the oxygen sensor melted against the exhaust pipe, and shorted the EFI circuit. All because I didnt have the o2 wires harnessed down proper. Ive learned everything so far the hard way and have been so stupid, but maybe this will help someone else.

 

this literal exact thing happened to me. good on ya for the PSA
