Are you sure you're getting fuel in those non-firing four cylinders? IIRC, TPI systems are bank fire.

I would check for loose grounds and make sure the injectors are getting a signal from the computer.

Check the injector circuit fuse under the hood, there are two of them, on for each bank.
Mine shorted out behind the pass side head after a trans swap. The wire didnt look bad until you pulled off all of the loom off of the harness and looked real close. I had to pull the intake to get to it.
