There are 2 02 sensors, one in each side of the H-pipe. There is a fuel pump relay in the engine bay fuse box. Its one of the big square fuses.

Fuel pump relay is under the drivers seat on a Fox Body, not under the hood...that's an SN95 thing.

No. It's not. Mine is under the hood right next to the A/C relay, near where the thermactor valve used to be. Mine's a 92 GT. Believe they changed it 91 or 90.

Check for spark and check your fuel pressure. O2's won't cause it to miss. I don't even have mine hooked up right now while i'm tuning it.
