93 4.0HO auto won't start turns over but won't start I'm getting fuel and spark the tps and cps are pretty new. I started it and it ran rough for a sec then shut it off now no start. I rebuilt it so it only has about 6000 miles on it also. Could the computer be bad? Also gives me 55 code

You say you have fuel and spark. But do you have a good blue spark? Also what kind of fuel pressure do you have? If you have anything other then a strong blue spark won't do. And you need at least 39 psi for fuel pressure.

Odd....The computer is often not the first thing to change with a no start....hope this was it for you, though. Let us know if the situation returns.
