Whippled 6.2 need help
Ok, here's what I know, was running 3,500-3,600 RPM's and the motor dies, won't restart. Checked and fuel pump not running, can hot wire around the PCM and get fuel pump to run and engine starts, traced it back to the fuel pump relay is not being pulled by the PCM, scanned it with Diacom software and NO faults stored, what would cause the PCM to not pull the fuel pump relays and allow this engine to start?? It is the pcm555 as info.

Sounds like it lost the fuel pump driver in the ecm. I have seen it before in the 555. Some can be repaired. Give Dustin at Whipple a call. He may be able to help you out.

Eddie, that was my guess, under further inspection when scanned its telling me I have 76% avaliable power, would that be a weak battery condition or something else? All other data looks inline

Mike, I've doubled, tripple, and quad checked every fuse in front and rear, I talked to Dustin today and he thinks it's prolly fixable if it's the drivers in the ECM for the fuel pump, gonna look at a few other things before I send it off, I'll take all advice I can get.
