Is there air in the line between the filter and injection pump?
 Rev it while looking at this section of fuel line and see if there is air bubbles in it.
 I'm thinking your fuel filter is clogged.
 A vacuum gauge on the fuel line will tell you when the filter is getting clogged.

i said im running a lift pump,and igot like 15psi,,,(same lift pump used in the isb cummins)measured @ the injection pump inlet,,it pumps plenty of fuel,,so no way on the air,,,i even ran it  from a can around the block

What'd the 12mm head come on? I just put a 10mm head on vw pump, but still wondering if it's going to idle with the gtd nozzles.

I'm not really familiar with the camplates. What sort of differences are there? Sorry, I'm not trying to hijack your thread.
