Injection pump threw that code when it died. May be fine, may not be. Depends how long you were running with little fuel pressure. Probably quite a while.

Are you just having a tough time getting it started? Once you completely drain that filter housing. It takes a while to get it filled back up. And then you need to crack the injection lines to get all of that air out. It can be a real pain and takes a while.
I'm hoping thats my problem. Yeh it just wont start. It briefly did when I put it all back together but ran like crap (2 or 3 cylinders)and died.

before you jump to conclusions make absolute sure its the vp44.
Put at least 10 gallons in the tank, I dont care what your gauge on your dash is reading. The sending level unit from the factory on 24valves in known to be false.... ask me how i know.
once thats done bump start DONT TURN IT OVER just bump the starter! the lift pump will begin to cycle for around 30 seconds. Do this a couple times to bring as much fuel to and through that pump as possible.
Next go to the injectors (19mm) and crack a few loose and once again bump the starter. If the pump hasnt given up the ghost you should see air bubbles and seapage from the lift pump pressure. Do this a couple times to get some of the air out of the system from when you replaced your pump and filter.
Now crank it over.
If it isnt the vp44 she'll chug a few times but she'll come back to life. rough at first but she will.
This is just a check to make sure you've bled the system and fuel is as far you can take it. Theres pressure checks and electronic run throughs which are described in the Haynes manuals and throughout the interweb also.
Do as much research as you can before you drop the 1500 on the new pump..... goodluck

Are you getting a good flow to the injection pump? I cracked the line at the pump and kept bumping the starter til I had good flow. Then cracked all of the injection lines at the head. A few of them started to bubble, the rest just weren't showing fuel. I finally had my buddy try to start the thing while I was watching a few of the lines that were cracked and it finally stumbled back to life and I tightened them quickly.
Before I rule the VP44 is dead I'm going to crack the lines. I know the lift pump is working fine now that I put a new one it it. I have fuel flowing for sure. It wont hole pressure though. I can watch it pump up to 15psi then it bleeds off quickly.

Just plain CRAZY!!!
Another 24 valve fuel problem that costs OVER a grand to fix.

Damn Jon, I know we've had our differences but I thought you were smarter than this. If you're going to fix this thing to keep and drive, is the cheapest Ebay pump you can find really the right answer? :fawkdancesmiley:
Well senior mustachio I'm here asking for advice. I don't want to pay a ton of cash but I was thinking with this set-up and the FASS system you coudln't really go wrong. So find me one of ebay
BTW our differences have been over dumb **** nothing personal.

The FASS isn't the problem in that combo.
So I tried bleeding the air out. I cracked lines 2,3,&4 and I get nothing. Not even air. The lifter pump will pressurize the filter bowl to 15psi but it bleeds off quickly. I checked all the fuel line connections and they are tight and not leaking. I'm pretty sure the VP44 is dead.
