wireing issue possible bad cpu

so i was driving last night and ended up dragging part of the harness that runs along the k member. all the wires got shredded. cleaned up the wires best i could. spliced new in that section of the harness. pulled all fueses and checked they are good.

here is the deal. im thinking the computer pooped out. tried to jump the a-b terminals and no fan comming on no check engine light is comming on when u turn the key on.

engine will crank but no fuel pressure. no power at the fuel pump relay at all. i checked every thing i could think of on the side of the road before i called the tow truck.

Once you verify you have the wiring reestablished if the light bulb isn’t burnt out, replace the ECM.


Happy Racing!
