I have a 93 JGC, 4wd, 6cyl that just won't start. I replaced the plugs, wires, cap & rotor, crankshaft and camshaft position sensors and still nothing. There is fuel pressure and coil spark, but still nothing. Please help, I don't want to keep on the wild goose chase

Sounds like you are on the right track. Try cleaning the TB (throttle body) and the IAC (idle air control) with carb cleaner. Remove the Intake hose from the TB and clean the inside of the TB using a toothbrush if necessary. Remove the IAC (located on the valve cover side of the TB) and clean it also. The IAC is what regulates your air at start up and idle. You may also want to check and replace the TPS (throttle position sensor, about $40) located on the rear of the TB. If these don't work, you may have a bad PCM (power control module). Good luck.
