no fuel at injectors
hello Got a 2000gmc6.5 turbo got fuel to IP no fuel to injectors solenoid clicks. I keep bleeding air out of vavle at top of motor before IP turn key let energize turn couple of seconds bleed air comes out then fuel flows do it again same thing. I saw before someone had an airlock where the air compresses like a spring they cranked for ever and finally kicked up and problem free. I hope this is what's going on. I have the rear 4 injectors loose and trying. conditions critical where could all this air come from? I know it takes a long time to start if i run out of gas thank you

Here is a PMD diagnosis procedure but it is often best to test with a known good PMD:

If you are getting that much air in the filter you better check the lines and maybe even the fuel tank sending unit for leaks-the electronic IP don't tolerate air very well nor do they tolerate a poor working lift pump.
Don't forget the o-ring on the ends of the feed line either.
Also make sure you have a diesel fuel filler cap-the gas ones are not properly vented and can cause starvation problems,even a plugged diesel cap can cause grief-do you get excessive vacuum when you remove the filler cap?
