Yeah I'm not sure what it could be, I'm starting to shotgun stuff. So far I have done the entire fuel system to rule that out and have a pressure gauge on that. Tried the PCM. Don't know if it's worthwhile to try the ICM but I have one of those ready to try. I have an extra battery so I could give it a shot. But if it's not a crank sensor, my next guess was going to be something shorting that's not playing nicely with the system. That's just the last thing I want it to be because that equates to a lot of probing with a DMM lol
