    Any ideas? It sputters, catches then dies. I test started it after the pump install, and it was okay. New plugs, injectors & computer...no start. Could it be that low on fuel (I ran it REALLY low, plus all the fuel being drained out of the fuel rails & such)?

    try the original PCM and see if it runs. Just don't do any driving with it.

    Even with the different injectors?

    Mine didnt start after the cam install, it took 6 or 7 tries, it sputtered and died the first few times also. Are all of the injecors wired correctly? Coudl one have been crossed?

    I wiggled all the injector wires, and it started, if that is what you can call it. Semi smooth idle around 800-1000 rmps. I did some searcing, and it is showing a P0200 injector misfire code. Also a P0106 MAP code.

    give it any fuel, and it dies.

    Loose injector wire? Are they all seated on their plugs securely? Hell i&#39;m just thrilled I guessed close. Might wanna make sure with Allen the comp is tuned for the right injectors or you didnt just get a bad pcm. It does happen.

    Unplugged each one and reinstalled. Still the same. Fixed the MAF problem.

    It will at least start & idle, just no more than that. Still the same P0200 code.

    Allen??? The retune said it was for the injectors, but there is a handwritten note in perm. marker on the body of the computer that says "defective"? It wouldn&#39;t have taken the tune if it was bad would it?

    This sucks. Looks like I am walking to work tomorrow.

    Update, cylinders #2, 4 & 6 aren&#39;t firing (passenger side, fromt front to back first 3 in case I&#39;m wrong w/numbering)

    All others cause engine to run worse when I unhook them. WTF????

    Did you remove a ground wire? Also, did you replace the injector connector and if so, did you solder all your connections? I&#39;d check for power at all the injectors. You should have power to one side of all the injectors when the key is on. The PCM grounds the other side to fire them.
