I finally replaced Injection pump. I used the instructions supplied from this site. The truck hasn't run this good in about a year. Thanks for all of the help.

Everything that I was looking for. Very informative. A big thanks.

Tried that. Got only a little fuel out of #1, not much. Still fuel out of #3 but not with the force I think we are looking for. If you think there is still air in the line I will continue to try. Runs off of starting fluid but the stalls out. I know that I was getting really yellowish color on the snow this winter when I would let it warm up. I suspected the pump for a while but wasn't sure.

1st injector from front of motor correct ?

It shot out of the #5 then dribble out of the others that got fuel.

Closed.

Checked fuel pressure, came in at over 10 psi. Cycled fuel pump twice to make sure plenty of fuel in filter. Cracked in succession #'s 1,3,4,and 5 injector lines and cranked over 6 different times and only got fuel out of #3 and #5 injector lines. Unhooked grid heater and tried the starting fluid, would run on that then would stall out. Did that procedure a couple of time. Recracked #1 injector line and still no fuel. Didn't mess with any relays this time and still no codes. I am at a lose. Had wifes car hooked up to batteries to make sure of good power.

I put new contacts and plunger put into starter from LarryB. It turns over the motor like a champ. I check and clean battery connections regularly. Sounds like I just need to push a little more fuel thru and try the starter fluid.

Last I checked I had fuel coming from 4 of the 6 lines that I could crack. We got fuel out of the third injector fairly quick and the others took a while. The fuel did look a little frothy like there was a lot of air in the fuel. The it started to run clearer.

I do get some puffs of smoke like one cylinder wants to fire. I had to convert to intank fuel pump when return line rusted off the top of the tank. I will crack the injector lines again and try cranking some more. I will also try a little shot of starting fluid. I will also hook a fuel pressure tester to double check fuel pressure.

I think the key might of been on. We cleared the codes and still no start. We tried for 2 hours and still no start. It acts like it wants to start but no fire. I have tried to start again and no codes back up. Is there another way to get air out of system if that is still the problem? Could it be the connections on the ECM or Crank Position Sensor since they had diesel all over them from the leak? Switched fuel relay with horn relay to check the fuel pump.

This is my first post to this forum. I have 98 24valve that had a fuel leak on top of the fuel filter heater. I fixed the fuel leak, reprimed the filter and fired for two seconds then died. I cracked the injector lines to get the air out of the lines and have fuel to all of the injectors. The truck will still not fire, acts like it wants to start but won't. I have good fuel pressure to the pump and no codes until switching relays. Codes 1688 and 1689 came up only after playing with relays. Any help would be appreciated.
