I put my new primer pump on today, which was pretty strait forward. Just make sure you take off that small inlet nozzle on the right connected to the pre-filter so that you can access the pump to remove it. My 24mm wrench was far too large to move in the cramped engine bay so I resorted to just using a pair of vice grips to remove the old pump. I cleaned it all up and put everything back together.

Still wouldn't start.

I pumped the hell out of my pump.

Still wouldn't start.

I cracked the nut on my #5 injector, pumped, tried to start to see if there was any diesel coming out of the line. No fluid whatsoever.

I tightened that nut and loosened the one on the IP for the #5 injector, repeated the process. Still no fuel running down the side of the engine.

I put everything back together and just pumped the absolute hell out of that primer pump. Jumped in, let it glow. BROOOOM! Started right up.

I'm not sure about what it was exactly that fixed the problem but its working now. And since I cleaned the banjo-bolt, replaced broken/cracked vacuum lines, fuel filters and the pump, I'd say my engine is running better than when I bought it. I took it for a spirited spin around my neighborhood and the performance has definitely increased, not a significant amount, but still noticeable.

I just wanted to thank you all again for your help!

Some times its real hard to prime the system. U have to give that primer pump a hell of a pumping. But if U pump it enough it will get out all the air without removing or loosening anything.

The air in the secondary filter will go out thru the bleed hole in top of filter, the air in the IP will go out the overflow valve and any air in the injection lines will go out thru the injectors.
