Truck died on the way home today and wouldn't start. Checked codes and have a P0628 that will not erase. Quadzilla Zillaraider II Std and Commander.

any ideas?

you have experienced a lift pump that has gone past its "best before" date.

The 0628 is lift pump out of range, basically speaking, it is dead, expired, bit the big one, taken the dirt nap.

But a positive way to look at it, its a good time to switch up to a raptor or airdog.

After posting, I did a search and found the exact same issue with somebody else. My truck died once while on freeway.......restarted on side of road and ran for a couple of days and then did it again.....made me think it was the new Zillaraider II, unhooked all of Quadzilla stuff and truck worked again. Reflashed my QRaider II and hooked it all back up....worked fine again for about 3 miles, then gave up the ghost.

All along, I just didn't trust the "New" fuel Pressure Transducer that I got with my ZRaider II due to the failure of the original style sensor. But no, it told me my fuel pressure kept dropping to 0.......now I know to believe my Commander!!!!
