yago,

What do you mean by no injection pump (IP) pressure? To have pressure, you have to have resistance to flow.

Do you have the pipes off the IP? There should be a little fuel flow out of the nipples on the IP when you crank the engine. Its not much and it won't squirt out.

If nothing comes out, there is probably air in the IP and it needs to be bled out. Make sure the air is bled out before you send the pump out for repair. Take off the fuel line to the IP and see if any fuel comes out when you pump the manual pump. IF it does, then put your finger over of the end of the fuel line and see it the hand pump developes some pressure. There has to be enough pressure to overcome the overflow pressure valve in the IP. If there is no or only a little pressure, you probably need a new manual pump.

Is this the IP you had on the engine before you rebuilt it? If it is an dit worked OK before, there isn't much you can to it to make it not work as long as you didn't take it apart.
