well after a long winter and lots of work, i fixed the 93 jetta crank gear and sold it , the car was to good for a doner, so the van got the 1.6 TD out of the 86, and the 86 got the van 1.6 na, wow it worked grate in the jetta,sold that one to.
So the vanagon got a dk trans from AA trans., new clutch pplate etc. and the 1.6td.
just trying to get thing done, motor and tranny are in will post some pic.s, I did some neet things with the turbo oil lines, motor mounts.
Now for the I need some help. I cant get the motor to rev up, it did when i first started it but after a few seconds it just ideals and will not rev up, i have primed it 3 times, will rev up about three times and then just idel after each time that i prime. help

Bubbles in the clear line to the injection pump? Plugged filter? Plugged screen in tank?

If you use "post reply" rather than "new topic", your post will appear in the same thread, be easier to follow and keep the main menu less cluttered. Air in the line from pump to filter means that there is either a leak upstream of the pump (toward filter and tank) or there is a fuel line restriction (clogged filter or in-tank screen). If you haven't already done so, I would start by changing the fuel filter (probably needs it anyway). Make sure to fill the filter prior to install. If that didn't cure the issue, I would remove the hose at the tank. The diesel should pour out. If it trickles rather than pours, I would drop the tank and clean it out. It would be a good time to replace the tank grommets and lines. There are online vendors with tank reseal kits (be sure to get the right year as the filler neck is different.

How did you do your pump timing?

What is the history of the engine and pump?

It there smoke when it starts up eh? How much?

I think there is good chance your cam timing is off now that you have a new timing belt. Folks reading this please correct this if I'm wrong. I don't know what the engine would do if the cam was off..... besides the notorious and terrifying valve slam!

Perhaps... also the pump is now a notch off in one direction or the other.

My bet is both are off as per the symptoms you describe.

If you remove the fuel shutoff solenoid in the IP and there's no fuel in it, then the IP has run dry. If it runs dry, prime the IP (procedure can be found elsewhere here) and run a fuel line from the IP to a glass jar with diesel in it. If the engine won't rev after a few minutes of running it from a glass jar ( to make sure fuel in in all injector lines and throughout IP), then it's not the fuel system on the vehicle that's the issue. If it runs fine out of a jar, then something is wrong with the vehicle's fuel system on the car itself.

If you include the injection pump as part of the fuel system, then that info is not correct. The vanes of the vane pump can stick and the governor assembly can be messed up causing a no-rev situation.

Sorry, I was looking at the fuel system and tried to describe the isolation of the fuel system to the vehicle body itself (inlet side of IP to the tank) and the fuel system on the engine (IP to the cylinders).

Did you have the timing belt off? If so, it is possible to index the injection pump pulley 180 degrees out if you only use the pump tool to line the pump up. The symptom of a pump 180 out is similar to what you describe. There is a notch on the back of the pump pulley to let you know that it is clocked correctly. If you did not have the timing belt off, excuse the post.
