Hey guy last night while on the way home I was fooling around with a duramax and suddenly my trucks engine died and I had to pull over off the highway. Still had power to all lights all my gauges and everything. My fuel PSI went to 0 at that time my pressure sensor is about 6 inches from going into the VP and my fass 150 is less than a year old. Idk how it would fail but I’m not sure what the issue is or what could have caused it. Anybody have an idea? I’ve loosedned injector lines 1-3-5 and have fuel squirting out when trying to fire. Any help would be great especially with the work week starting tomorrow! 

Check it for trouble codes. Take a little guess work out of it. Lift pump fuse blown? VP?

Truck displayed no codes. Had a friend with more knowledge than I have and he disconnected the quadzilla and truck fired right up. I plugged the quadzilla back in and now it runs fine 

The only thing I can say is have the Quadzilla checked out. Really the Quadzilla should not be able to prevent starting. It only hooks up to the CANBus, VP44 wiretap, and the MAP sensor. Unless it was fouling the wiretap some how.
