i'll try and get to the shop in the mid AM maybe closer to 11 since traffic sucks between 8 and 10 for me to get there. and hopefully you will be able to get it back on the road.

- Start date
hmmm but wouldnt that throw a security light? symptoms could match with a crank short run then no start
It would give a code also. Snap-On scanner said no codes present. Its gotta be fuel. I just dont wanna burn starter out. hoping for some insight.
I burnt my starter up doing the same thing...turned out to be the fprv was loose.
Check your cranking fuel pressure with efi.

Three things to check:
Injector return lines. (not the one from the pump) Is there fuel flow? Fuel = Good
Pop the glow plugs. With the injector fuse pulled, crank. No Fuel puffs out of the holes? Good. Fuel puffs? Hung injector draining the rail.
With the glow plugs still out. Put the fuse back in. Crank. Puffs out of the GP holes? Good. Injectors are firing. No? Find out why the ECM is not commanding the pulses.
Even if you don't get return from the injectors, popping the glow plugs makes it crank a lot easier to prime the system.

Well, I went to replace bleeder and threads came out with it. so, I guess it's a bad idea to cut down a bolt as a replacement.
yes that is definately a bad idea. I have some logs.. there is a fuel pressure problem.. most definately from sucking air through the bleeder screw. heres some logs
I have stock filter head i was going to post up for sale , not shure how fast you need it or if you could get one closer ?

now thats what I like about this place. always someone around to back up a man when they are down. that may work as a plan B if plan A goes down the tubes.:thumb:
so I fixed bleeder, also line going to #1 injector was weeping up between line and nut. After line repair, it made an attempt to start twice. now just cranks again.
Since its new do you have good oil pressure?
I may be way off , I am still learning but didn't I read somewhere about low oil pressure no start? Also we have had some antitheft problems with no codes setting also.

40lbs o.p. Well I checked for signal with a vantage meter and theres only a quick intermitten 15v, which would explain random fire. now I guess its an electrical problem. any hints what to look for?
I ran into trouble with 2 grounds on the side of the block. There were 2 or 3 on the passenger side up front by the ground cable and then there were 2 we forgot on the drivers side of the block towards the front.
they will start with no oil pressure
if its an anti-theft problem it will start for a split second then die. Also, the security light would be on and the tech 2 would say "VTD fuel disable - yes" under the 'engine data 2' screen.
