I have a 96 2500HD with the 6.5 TD. Just bought it. Ran fine when I drove it home. Next day would not go over 30Mph. Test and parts replaced:
1. Tested lift pump no fule from test valve did not die. (you can here LP before start)
2. Replaced fuel filter and retested and did some times.
3. Checked voltage to ops while runing ~13 (no load)
4. Replaced LP and tested LP fuel came out and did not die.
5. Drove truck and worked ok for a 3 miles then can't go over 30mph
6. Tested lift pump tested bad engine died.
I know it is a 96 so obd II so don't need OPS for working pump? Does the other relay ever go bad or get week? Can I have bad OPS and other relay? Where is othe other relay?
Thanks
