Did the lift pump fix this?

 

Crack loose a couple injectors and let the air out. Snug them up when its fuel only.

 

Not sure yet.

I've replaced the lift pump etc and now im at the point of bleeding the system. But nothing happends when i push the primer button, ive pressed it like 500 times and no fuel is coming out from the bleed screw on top of the filter. What should i do?

 

Power up the lift pump, with the bleed screw open. See what happens.

 

How do you mean power up? It is mechanical?

 

is it driven off the engine??? (shows how much I know about diesels. ) I thought the lift pump was electric??

 

The lifter pump on a diesel is just like the old mechanical pumps on a car.

Something you can try is adding an electric pump to bypass the mechanical pump. I don't remember the pressures or volumes needed for certain, but i seem to remember a 3~5 psi fuel pump for a carbed car working good.

Something else I just remembered, you might have the pump lobe fighting you. Try bumping the engine over just a little bit and try it again. The hand primer won't pump if the pump is in the wrong spot, but will still feel like its making pressure. Good luck.

 

So, now i've got fuel to the filter and to the IP. All it took was a 5 sec cranking and the lift pump pumped like crazy.

BUT, another problem. It just wont start! I've tried loosening the injectorlines on the pump and by the injectors, not at the same time of course but i can't get it to start! It's not coming any fuel at all to the injectors. Is all the fuel going by the overflow valve at the IP?

 

failed injection pump?

 

Oh don't say that No, it's a possibility but it worked fine before the filter change so it shouldn't be it.

I've cranked it like 15 times with and without starterspray (yeah i know it's bad) but it wont give a sign of life, not even a bit except for the starterspray.
