I finally got the engine dropped in the Daytona (88). The only mods I made are 2.5 injectors, and my TBI cam, which was installed in the engine before the rebuild. It runs really rough and I can't find the cause.

I replaced the cap, rotor, etc. and no difference.

Any ideas would be gretly appreciated.

Thanks!

There's an issue with the injector harness, most likely. When you swapped injectors, you likely pulled one of the pins out of the injector connector. Remove them again (don't pull at the wires) and push the contacts back into the connector. Also check for any shorts, etc on the rest of the injector harness.

Same thing happened to me when my car actually ran ::stupid electronics::, and it was remedied when we fixed the ignition timing. I also thought it was a fuel delivery problem, but this is a much easier fix, so try it first.

OK. I put my old fuel rail in the car and it comes down to I believe a bad pick-up coil. I tried to time it and it only hits on and off all the way across the board. I'll fight it some more this afternoon.

This has happened to me twice, both times after the car sat undisturbed for a while. Both times it was the injector harness, the fuel injector connectors had started corroding and that prevented good contact with the fuel injector terminals. Both times the problem went away after cleaning the injector harness's terminals. This was my experience with code 26.
