There's a thread in the FAQ, I believe, about a known grounding problem with the igniters (it's an internal issue). See if you can find it and see if the fix listed works for you.

Thanks. I already had the ground mod in place. I replaced the ignitor and it is not much different. WIth all the injectors unplugged it behaves EXACTLY THE SAME as with them plugged in. I believe it is sputtering a bit and firing into the intake runner due to fuel from the cold start injector. It sputters a bit more consistently maybe with the new ignitor, but no real change. Also no different with plug to injector resistor connected or not.

So without the injectors making a difference, and good fuel pressure, is it fair to conclude that I'm down to injectors not opening as my problem? If so, i've already tested the injector resistor with an ohmmeter, simple device. So now am I to check wiring continuity to the ECU, repeat the voltmeter tests at the ECU from the TSRM, and then swap ecu if those check out normal?
I am out of other ideas at this point.
