I just rebuilt the 3.0 in my 94 voyager due to the rear cam locking up. I have replaced both heads with new, hone job with new pistons and rings new main and rod bearings, waterpump, timing belt and tensioner, plugs, wires, cap, rotor, all seals, new oil pump yada yada yada. I know my timing marks all line up as I have checked, rechecked and then checked again. when I went to fire it up I got irratic firing back through the plenum and a strong oder of fuel. I have fouled two sets of plugs pulled and dropped pulled and redropped the distributor. Still fires but irraticly backfires through plenum. I did find that there were some wires on the ECM side of the injector harness that the casing had cracked and it appeared that the wires were possibly shorting on each other and or valve cover. They were not broke or coroded so I liquid taped them and reinstalled new plugs same thing? I have no codes in ECM other than 12 and 55 that is because I disconnected the battery cable with hopes that some magic may come my way no luck. Anyways with the PCM giving me codes is it still good? Or is it possible given the short issue I found that the fuel driver side can be wiped out and still get codes? Or is it possibly in distributor it does have 250000 plus on it? I am at my wits end just curious if anyone can give me some insight into this. I am honestly thinking myself PCM is good and distributor is bad as it is either the internal crank and or cam sensor that has failed?
