Update on the 6.9
I devoted most the day to the 6.9 to see if it would run. Pruged all the fluids that were put in it to soak and free it. Reinstalled the old GP's, Changed the oil & filter, fuel filter, primed the fuel filter, and oil filter. Put fresh fuel into an aux tank, didn't trust the trucks tanks after 2 years of sitting.
I was able to bleed the fuel filter housing shrewder valve, but could not get good fuel out the steel output line from the fuel housing going to the input to the IP.
I am going to get some clear line to make sure the fuel pump is sucking from the aux tank I filled the new filter and it took a lot of fuel to fill it, I was wondering if the fuel out the shrouder valve was from the fuel filter and not the aux tank? But, the old fuel filter was funky looking, it had some water in it. But I opened the output fuel line at the fuel filter housing, and I did not get the fuel shooting out while cranking that I should have, I did finally get it at the shrouder valve.
The inj pump is not providing fuel, I was wondering if there was a filter in it also. If not I as Seawalkersee stated the IP is bad. Following the steel input fuel line to the IP, looks like there may be a filter in the IP? Looks like you would have to pull the IP to get to it?
Another question if you look at the pic of the IP the 2 bottom wires have voltage with key on while cranking. The top wire (yellow) has no power ever, is this correct? I do not have my GP's connected because 3 of them are bad and I saw no need, I used a little starting fluid as a starting agent to replace GP. If the eng ran, then I was going to buy all new GP's, but if I have to swap this eng with the 7.3 those GP's are different, so I didn't want to waste more money.
So I guess my question is do I have power at the IP at the correct place to allow fuel flow? And is there a IP filter that I should replace?
It's looking like I should quit and just swap in the 7.3 but I see a lot of different and extra wires that look like the swap may be a real pain???
