ive got the cam and the crank all in perfect timing but there is no bit in the fuel. ive lined up the hole and the slot in the injection pump. however it doesnt seem to be going for me. is there some thing im missing here?

If by bit you mean the tool to align the pump then it doesn't go in far. I usually wiggle my IP sprocket back and forth before timing to make sure that the tool is in place.
Other than that I am not sure what you could be talking about?

i wemt out to the garage and checked the voltage on the solenoid behind the pump on the top. it has power it floats between 0.38DC volts-12.75DC volts

Shouldn't float. 12v consistent.
Crack a line at one of the injectors and turn it over to see if there is fuel at the injector.

i did that yesterday to see if the pump was actually pushing out fuel. i had to hold the throttle wide open to get a decent amount out though.

what do you have the timing set at?

He means: when you used a dial indicator to accurately set the injection pump timing, what value did you use?
My suggestion: start back at the beginning... what are you doing, why are you doing it, what have you done so far? Your first post kinda leaps into the middle of the story and we're gonna play 20 questions for a while if we don't start back at the beginning. :lol:

i destroyed the lifters a while back ao i pulled the head to c the damage. installed a new head guasket, liters, cam, timing belt and timing bel tentioner. ive put the timing marks dead on several times. but as much as i try i cant get the pump timing right. ell thats what i think the problem is

OK, a couple of thoughts:
- assuming the lifters got destroyed due to valves colliding with pistons, was the head completely disassembled and all components checked ? Enough force to destroy lifters usually means as least some of the valves will have deformed shafts that won't move freely and can jam open.
- did you prime the injection pump by applying suction to the "Out" fitting until no air came out ? If not, it can take a lot of cranking for the system to prime itself
- if you are primed, are you getting any fuel at all when you crack an injector line ? Even with the timing out of whack you should get a bit of fuel at the injector line, with the key in the on position
- does your injection pump pulley have one central bolt and three smaller bolts, or just the one central bolt. If it just has the one central bolt you need a dial indicator to accurately set the timing... aligning the marks gets the belt in the right spot but the precise timing can still be way off:

the head was not completely disassembled i just pushed down on the valves and they cam out straight so i figured that was ok. is it? the pump has fuel coming from the cracked lines to the injectors. the pump is the 3 bolt on a center bolt pattern
