Default Help goning nuts

Was running great one day then the next cramp. Starts and runs
but no power when you give it fuel. Check just about everything, fuel pressure,throttle body, knock sensor,oxygen sensor,injector leak down,
idle control,tps ,replaced MAF ran diagnostics on computer nothing comes up wrong.Anyone run it to this problem. Oh its an 85 I would like to find a 86 computer.

Have you checked the fuel pressure under load? Tape the guage to the windshield and go for a ride. A clogged filter or weak pump will show good pressure at idle but under a load it will drop off. Reving it in nuetral wont show it either.
