My BIL decided to change his trucks fuel filters a couple weekends ago. Long story short he broke the top filter housing cap and had to get a guy that works for us come help remove it. While waiting for help he decided to go ahead and change the lower filter.

Once the broken cap was removed they vacuumed the housing out and installed a new cap and filter. After the system failed to self bleed they hooked a bleeder fitting up on the fuel cooler back port. They got the truck to crank and let it run for 20-30 minutes at idle. They then shut it down and replaced banjo bleeder with factory banjo bolt and it hasn't cranked since.

I showed up Monday morning and removed the top filter housing and cleaned it( there was plastic debris and metallic specs in the bottom of housing) and also blew out all the fuel lines that I could disconnect at both ends. I tried to bleed the system again. Flow to filter housing seemed weak and the lift pump was a little noisy so after a couple hours of unsuccessful bleeding I replaced the lift pump and put 2 new filters in.

Still no start. I then removed the stand pipe in the upper filter housing and cycled the pump on 20 times and tried to crank it. Nothing. But when I opened the filter housing back up to reinstall the stand pipe the upper housing was bone dry. I thought I had finally gotten the suspected air pocket in the high pressure side. But after refilling the housing with fuel and reinstalling the cap I have nothing.

I've worked on this thing for 20+ hours now and am way past frustrated. Hoping someone has some insight. I got the advice to remove the stand pipe from Lucas @mysterync who was kind enough to take time from his day to help.

Thanks for any advice or suggestions in advance.
 
Oh and a guy hooked his computer to it and said the rail pressure reading is 0. He said he thought the hpfp was dead but wasn't sure, and offered to replace it to see if it would fix it for $6500 lol.

The truck is also throwing a code p2291 which from my Google foo seems to not narrow much down.
 
Crewcab? 4x4? Leather? I'll give you $5000 for it :flipoff2:

I know a common issue is the frame mounted filter not being tightened enough, but that usually is just a hard start, not zero fuel flow.

I dont know how you are bleeding fuel. But here are a few ways

We initially were using a fitting that replaced the rear banjo bolt on the fuel cooler as shown in the video. The fitting we used was part of a fuel injection test kit and only had a 1/8 nipple. It broke so now I've been bleeding through the shcrader valve on fuel cooler and cracking the rear banjo open while pump is running.
 
I just ordered this so maybe it will help.

we made one at work where we just ordered a banjo bolt for the fuel cooler drilled it and put a fitting in it.........and a starter after well you know.
 
3 more hours this evening messing with it and still nothing. No air visible in the bleeder line.
