wiring harness fried under manifold, replaced harness, distributor, air mass meter,(2) ECU,(2) fuel control modulator, injectors, TPS, most sensors, new plugs, cap and rotor. Got to start but sounded like it was being choked. Catalytic began to glow "red". Punched out CC, tried to start again, BOOM!!! Blew muffler completley apart. Now it starts easy, but still sounds choked, exhaust smells like gas and doesnt want to rev up, will backfire if reved up slowly.



Any ideas to this continuing dilema? Any would help.

Did you get the firing order off? You say you replaced the distributor, it sounds like you either got the wires on assuming the distributor rotates the other direction or the rotor is off 180 degrees.

It wouldn't run if the timing was off 180 degrees, but all you symptoms point to the same problem. The cat was glowing because it was being asked to burn so much fuel. The backfire that blew the muffler apart was because there was unburned fuel in the exhaust that was ignited. The exhaust smell like gas because, well, there's unburned fuel in there.

Unfortunately you've made so many changes at once, fault tracing could be difficult.

  1. Check your injectors, if you have the wrong ones, the thing will never run right. (Put in you old ones if you still have them.) Or maybe you have the wrong fuel computer - one designed for different injectors.
  2. Check ignition timing - it sounds like it could be way retarded.
