For some reason or another I had to remove the full power screw from the IP on my Dad's 93. Then when I was putting everything back together, I couldn't get the fuel banjo bolt to thread back in, so I gave up on it for awhile.

I left the pump like that for about 2 months. The inlet where the fuel line goes was left open to the air for 2 months (got busy with work and stuff) Last weekend my brother gave the banjo a try and gets it to thread up on the first try.

So, we get it all back together and it won't start. It will crank and fire for a split second, then it dies. Ok, fine.. We try bleeding air for the Injectors, fuel squirts out there, But it still dies. Ok, will maybe the LP is hosed. So, we replace that... same results, there goes $88 from Napa. OK, will maybe the fuel filter is clogged. So, we replace that with no results.

What else could it be? I said maybe we should try turning the full power screw in some more, but it looks to be in the same amount of turns as on my truck.. I think thats what needs to be done, but I wanted to check here first. I hope to God it isn't the IP. I just priced them

 

When you bled the injectors, did you leave them open while trying to start the truck. When I had my 2000 and ran out of fuel (LONG story), I had to crack and leave them open and tighten them while the truck was running. (that was a little unnerving)

 

The Head screw the fuel screw in a lil more. I worked on mine the other day and thought I counted the turns but I guess I didn't. It would start then die, screwed in about 2 turns and it ran ok. Then I screwed it in to runaway then backed it out 1/2 turn. Good luck.

 

Yes thats how we did it. We would crank the truck over with the injector lines cracked open. It can't really run right now though. It just fires for a split second, then dies.

I should also add the truck was really low on fuel as well. My Dad always runs it really low. I bought 5 gallons of fuel for it for good measure.

 

Might try disconnecting the grid heaters and starting it on a little bit of ether or WD40 to get the fuel system primed. That will help you eliminate air in the system as a potential problem.

 

Don't mess around with the ether...

Get 5 gal. more fuel so you know it's got plenty,crack open every single injector line and leave them cracked open, then hand pump that lift pump until there's fuel coming out the cracked nuts, leave them loose until it's running on it's own. If theres alot of air in there it will be a pain to get it to run, once it's running tighten them. I would then one by one loosen them again and look for air bubble in the fuel coming out, and listen for the engine to run smoother, do this on every one of them.

If you can't get it to fire and run you should then go back to the fuel screw for a tighten or two.

 

did you blow/clean out the banjo hole?

 

No I didn't. We noticed how small they are though. Could they not be letting enough fuel through to let the truck stay running?

 

got an air source handy ? try putting an air line into the filler neck witha blow off nozzle on the end, pack around the blow off tip with rags to form a bit of a seal, apply pressure to the tank, and watch for fuel up near the fuel filter.. loosened of course. leaving it open that long might have let the fuel drain clear back to the tank. don't put so much pressure that you could pop the tank, just enoguh to push it to the front of the truck. when it starts coming out the loosened fuel filter, tighten filter again and then try with cracked injector lines, at least then ya know ya got fuel that far.

 

Sounds stupid, but my truck won't bleed unless I crack injector lines on two injectors.

 

I forgot to mention I had all the IP parts in a plastic baggy while the truck was down.

I think we did have more than one injector line open at a time when we were trying to start it.

 

Going to give it another try today.

I added 5 more gallons of diesel, and we're going to turn in the screw some more and hope for the best.

 

Crack all six and be done with it, it's messy but sometimes necessary. Not all trucks are the same but you might be surprised at how long it takes to get the air out sometimes.

 

Got 'er running. It needed 2 turns to idle weakly and we went 1.5 turns more to make it run healthy.

 

Right on John....good on ya!!
