This is on an '01 H.O. vin 7, manual truck with 98,000 miles. Drove the truck today and did just fine nothing seemed wrong. Decided to check fuel pressure and volume since I am getting real close to the 100k mark and end of warranty. Hooked the guage up got in and truck would not restart. Lift pump wasn't coming on and check engine light came on. Checked codes--p0230 and p1689. Reprogrammed ecm from super chips back to stock so if I needed to take to dealership, but now the codes will not reset but truck is still dead. Did a search and could be possible VP. What do you guys think? If it is just the LP and VP, then great still in warranty but if not I will try and fix my self. Any help would be appreciated.

 

P0230 Transfer pump(lift pump) circuit out of range.
P1689 No COMM between ECM and injection pump module.

Sounds like your lift pump went south and took the electronics on your injection pump with it. See the dealer.
