Is the stop solenoid getting power? There should be very little fuel actually coming out of the injector lines, it needs a few cycles to produce even a small drop of fuel out of the delivery valves.
i think it is how would i know if it is or isn't?

With the key on, removing the wire to the stop solenoid and touching it on and off should hear a click-click-click for every on and off of the wire.

I would put an inline low pressure pump to ensure fuel is getting to the injection pump.

you got an air leak. the pump should NOT lose prime once it is primed..

I agree with a fuel line leak. The pump wont even think of movimg fuel if there is air inside of it. The high pressure pickup ia at the top of the pump pretty much.

I'm gonna pickup a mr gasket diesel lift pump at oreilly for 60bucks I figure it can hurt in the long run anyway. I'm also gonna get a vacuum pump and try to get fuel fully pulled threw the return line maybe my pump isnt primed adequetly.

I honestly love having my electric pump inline, never have to worry about loosing prime.. and if you run out of fuel, it is a non-issue to get going again. Because you won't notice you are out of fuel until your pump is empty..
Throw the pump in the mix, but in the mean time try an IV feed of diesel. A funnel held up with the fuel line running to the pump, and fill it with diesel. Obviously need a helper.

i also removed the plunger from the solenoid and tried cranking.

Does this car still have the water seperator beneath the rear seat area? If so, delete it.
Have you very closely inspected the entire fuel line running under the car?
Have you popped open the fuel tank tin plate (in the trunk) and inspected the fuel line which comes off the fuel sending unit? Sometimes, the rubber line dries out and cracks or the clamp cuts through the hose.
How about the fuel lines under the hood leading to whatever fuel filter you are employing?
I bought one of these little green Mr. Gasket $60 pumps from OReilleys last year and it did not work....then, I lost the receipt in the mean time. Report back how it works for you and I will go buy another and use the receipt to return the original!

all lines are good the water seprator is in a dump somewhere in pa never to add air to my fuel again. Im not gonna get the mr gasket pump all signs point to garbage based on reviews I read. There is a few diesel shops in town I'm gonna check out and see what they have.

if you added the mk1 filter check there. I would suspect anything you have done to be causing the problem. Plus the MK2 inner fuel line doesn't like to mix with the barbs.

Run clear hose for supply and return into a separate container of clean diesel. Place the container so that the top of the fuel level in the container is above level of the pump (this will prevent fuel from siphoning out of the pump). Crank it over to see which way the fuel is flowing in the clear lines. If fuel is not moving in the clear lines or is moving backwards, then the issue is with the vane pump portion of the IP. If it is moving the correct direction keep cranking until the air is purged from the pump. If there is still no flow to the injectors with the stop solenoid plunger removed then the issue is with the low pressure control portion of the pump - accel lever to shaft orientation/control collar/lever assembly/max fuel screw setting - or the high pressure portion of the pump - plunger/head assembly.
FWIW, when I have disassembled pumps and then assembled using vaseline (recommended lube) on the moving pats, I have found that sometimes it will take a fair bit of cranking to get the fuel flowing from the delivery valves. I think it takes some rotations before the vanes work exactly right in the vane pump and then takes a little while to get the delivery valves to pass fuel even if the pump is full.
