Good that you got it figured out.

 

any fix to a injector pump without replacing it the chevy place told me its the injector pump is bad with a code but not doing a test on it now its 2200 to fix my 6.5

 

What code are you getting? when mine went bad there were several codes including one stating no combustion in any cyclinders

 

And possibly just the driver is bad, 352K on yours Dave you needed a fresh IP, but I bet a new driver would have fixed it to at least an operable vehicle.

Jason run through this checklist 6.5 Engine Diagnostic Troubleshooting Checklist copy/paste here if you want to see what folks here have to offer, I dual post but spend most of my time on TTS and a larger 6.5 following there than here
