Ford 7.3 Passenger Bank Dead

[NitroJoe]

Understood. I will setup an account to host.

Also I will test:

1. Remove Chip and start record video
2. Replace IDM with 'used' unit once it arrives
3. Compression test passenger side
4. Report findings

Thanks again everyone. I have homework after work.

Here is the buzz test file:

Here are two files.
1. Cold Start - Yes, it is a long hard start, prob due to pass bank being dead.
2. Under VC and injector inspection.

Cold & Injector inspection

My camera work stinks, was trying not to kill my phone or get hurt.

My fuel pressure gauge was going crazy, It is connected to the front head port on pass side. Don't understand how it could be that high, if accurate.

Let me know what you guys think.

All of these links take you to lime wire (hosting site) for the files.

Thanks again, Joe

Have you tested fuel pressure someplace before the head? or Other head?

That is too much pressure it would mechanically lock the injectors.

I tested the bowl pre-filter. I will move the gauge to the post-filter connection and test again, take the return line off, blow it back to the tank, and listen for bubbles.

I do have an FPR rebuild kit that can be installed as well to ensure the spring pressure is not the issue.

What brand is the UVCH.

What brand is the UVCH.

Dorman, both sides.

Dorman, both sides.

I've only heard bad things about the dorman uvch. I strictly use the motorcraft one though there may be others that are worthwhile, but not the dorman.

Never had a DOA Dorman, but after about a year all the wire sheathing is cracked and splintering.

Plenty of other DOA Dorman things though.

I did bench tests for continuity and ohms before installing, and they passed. I am awaiting the second IDM so I can continue testing.

The fuel bowl return line was disassembled last night. I put 100PSI through it to the tank and got plenty of bubbles. I will reassemble it with a new blue spring and poppet and then test the fuel pressure issue.

Lastly, test new (used) IDM with and without hydra chip. Also, I bought a harbor freight diesel master compression tester to test the passenger side (if I can get their fitting to screw into the head).
