Any ECU codes?

If you don't get spark it's usually a wiring problem. Has it worked before and stopped or it never worked?

I think the problem has to be either your ECU, wiring or igniter chip.

how badly was it cut? i had one that was that badly cut and i tryed and tryed to repair it and i couldnt get spark or fuel. Put a new harness in that wasnt cut, voila, no problem

if its been cut up by the main part of the harness, where it comes out of the firewall and then is supposed to go down by the battery box, that could be the problem, thats where mine was cut.

Please please be careful with the wiring. Certain things can get ruined if you wire them in wrong. Like MAF to ECU connections - you can ruin your ECU.

Where was your wire harness cut? near the fuse box or at the firewall? You have the ECU plug so I'm guess it was just cut at the fuse box?

That shouldn't be to bad. just double check stuff that you wire yourself.

gook luck
