Hi guys. I have a 2001 7.3 Ex with 160k with a PHP and some supporting mods. Recently truck has been having a hard time start (as in it would seem like it wanted to stall, or was having "hiccups"). This would only happen during a cold start (not actually cold, never below 50). After running it and driving it, it would start fine. I cleaned battery terminals, and made sure my tuner had a good connection to the pcm. After I did this the fuel gage would not work (it says it was past full), the tachometer doesn't work, and the power seats don't work. And truck was still having the same problem getting started, but ran and started fine after it was run for a little. Scanned it and said there was an issue with a fuel pump relay. I am stuck here and don't really know what to do next. Any help would be greatly appreciated.
