    Did the timing chain jump a tooth or two? What happened just before you started havng problems? If it's cranking and backfiring, it's gotta be the firing order or the crank is out of alignment with the spark.

      ok it started with a missfire. i found that it was the wires but all of the wire at night they lite up from coil to the plug like having 6 neon lights under the hood
      then when i got the new wires it got worse
      so now i tryed coils then injectors then module then last night i pulled it in to the gerage because a tire hade gone flat while it sat in the driveway and now it just wont start
      is there any way to check the timeing chain with out taking the car apart

        Doesn't sound like a jumped tooth, it sounds more of a problem with the coil packs and the firing order. I know you've checked the order, but I'm thinking the problem is somewhere within that area. Maybe a bad coil...? Dunno, I'm stumped.

            You sure you got the 3/6 wires right? Those two are out of sequence from the 1/4 and 2/5, when putting new wires on I got them backwards once.
