Hopefully the 04+ guys chime in on that. Without seeing it though, my gut feeling is that there is either a bad section of wire, corrosion, and most likely, the ground for the fuel pump. I'd start by checking the pump ground for corrosion.

I appreciate all the info bud. I'm about to the point of buying a donor motor and building the thing.

I understand troubleshooting can be annoying, but If this is a fuel pump or grounding issue, you'll be throwing your money away because you'll have the same issue even if you went back in time and grabbed a brand new engine off the assembly line. Trust me, I used to be a parts swapper, and I've wasted a lot of money and time versus me not taking the time to figure the real problem out. I hope I'm not coming off too harsh, my only intention is to help you not make the mistakes i have. In the end, it's your choice, and I wish you luck either way! We're always here when you need help.

I'm just worried this motor is about to blow up. I've had a lot of problems with it and just tired of it. plus side I'm wanting to go with a turbo application and to make the next motor last I'm wanting to build it.
