Hi all. I think I got air in my fuel system. Advice won't be greatly appreciated on how to correct. This is what I did.
- Replaced the underbody fuel filter. Drained ~1 to 1-1/2 gal fuel.
- cycled key three times.
- started and got rough. Died once. Restarted and idled for ~10...
Have a couple problems.
1. Changed out all 8 glow plugs and wiring harnesses. Ran fine, with exception the Glow Plug Control Module (GPCM) is always showing 6.5 volts to the glow plugs with the ignition key off. Does not have the old relay version.
2. Changed out both fuel filters as per normal...
