Engine/Transmission (1998.5 - 2002) air in injection pump

[JFringer]

just wondering if anybody has seen this before. my buddy has a 02 2500 auto,twin turbo, 200hp injectors, fass lift pump, edge juice, and water meth injection. the other night after running it hard all night he was doing a burn out and was at about 3,000 rpm and the truck just shut off. he had it towed after it wouldnt start back up. the next day i took a look at it and checked the voltage to the vp and it was fine, checked for trouble codes and there were none. i cracked three injector lines with no fuel coming out after 5 seconds of cranking. so i cracked all the lines. after about 30 seconds of cranking all the lines had air filled fuel coming out. after bleed all the air it fired right up and ran like new. he had a full tank and said he never lost fuel pressure before it shut off. What would cause this to happen?

I have had this happen before to my truck, and I have seen it with other trucks, most specifically on the Dyno.

When you are running your truck extremely hard, a lot of fuel is going through the injectors. If you just drop your foot off the accelerator, the fuel stops at such a rate, that it sucks what is renaming in the VP44 out through the injectors. At idle, the pump is not pushing enough fuel to keep up, and it bleeds the fuel lines.

After a hard run, let off the fuel a little slower and/or burp the throttle while it is coming down.
