Yup!, crack the nuts on the injectors and turn the motor over until diesel starts to seep out of each injector. a lift pump would would help here too.
I dont know if its just me, but every time Ive had my injectors off the car, or even when I removed the cylinder head and replaced it with a new one, I didnt have to prime the injectors or anything?
Was I just lucky or am i missing something? Twas the ABL engine.
Fired up after a couple of turns

The ABL is a gas engine so there is more than one conversation happening here.

No, the ABL is the diesel engine code for the T4 vans in europe. I sold a starter for such an engine yesterday. Itīs the same engine as the AAZ.

true. keep in mind that the system is self bleeding. no real need to crack the lines unless all of the entire fuel system has been drained of fuel.
Very early versions of the Ve system actually had a primer pump installed on the fuel filter housing but it was a one year only type of deal.

cracking the injector lines is a good way to troubleshoot priming issues and save the starter though :wink:

making 155 bar (hydraulic pressure too might i add) on four injectors probably takes some energy.

And I think that's the subtle difference... cracking the line is a *troubleshooting* technique IMHO, not a required step to prime the system. The pump is pushing 200 bar fuel thru the hard lines... a little bit of air in the lines is not going to hold it up. So, not a required step to "prime" anything.
On the other hand, as a troubleshooting technique it is very reassuring to crack a hard line and see the far end leak a little diesel... tells you almost everything is working and you're almost there !!

oh ya ive done that and i got fuel in all the lines. but i cheacked the power to the glow plugs and i got a steady 0 DCV . thats what i assume the problem currently lies
What voltage to you have now?

10.56 DCV was the highest but the battey is charging cuz it was dead so that might have some thing to do with it. is there any reason that the cam would flip 180 deg out?

Well, this thread has become a dogs breakfast. Lets start over:
- you were roaring along at 4200 RPM on the highway and it sounds like you blew out the timing belt 'cause all the lifters shattered
- you pulled the head and believe all the valves survived because the cam was able to move them
- you have replaced the glow plugs, relay, and confirm that you have at least 10V at the glow plug buss
- you've reinstalled the head and timing belt and have aligned at least some of the timing marks
- it sounds like you're getting fuel to the injectors
If the above is pretty much the story, then:
- have you done the full timing setup (crank, cam, pump), with dial indicator, as per the service manual? My sig has a HOW-TO with some pictures that may help.
- what *exact* compression are you getting, on each cylinder?
Diesels need fuel, at the right time, with enough compression to light it up. Sounds like you have fuel, so you need to carefully check the timing *and* confirm the exact compression on each cylinder. Otherwise you're just guessing and throwing parts at it, IMHO. :roll: :wink:

no one in this area had a guage the went higher than 300psi. so all the cylanders have 300 psi+. and no there has benn no dial indicator used at all. just the timing tools that vw has (cam lock and pump pin) and the mark on the bell housing
