I remove the line at #1 and while cranking it blew tiny bubbles out of the injector at each compression stroke nothing out of the line. Check injector #2 & 3 and i got a little out of the line but nothing came from the injector. So I think now # 1 injector is the problem. Can anyone see anything wrong with my diagnose?

if im reading this right, you took the injector line off and turned it over, no fuel came out of the injector line from the vp44 and you saw bubbles coming from the injector tube in the head?

Yes

I am no expert on injectors but that sounds like it is stuck open. why dont you pull out and see whats going on with it.

I would say you have either a sealing copper shim that is bad or a injector pintle/nozzle that is leaking. Time to pull them and look at the injectors too. :rolleyes:
