1995 K2500 6.5 with no mods. Ran great on Saturday. Went out Monday morning and she cranked but would not start. Checked lift pump. Getting fuel to IP (loosened line and get fuel when key in run). Cracked injector lines, no fuel on crank. Installed spare PMD. No help. IP had around 90,000 miles, and I had a new one in the garage, so I changed the pump. Still no fuel coming from IP. Shutoff solenoid seems to be working properly. Could it be the computer? Does the 95 have a cam or crank sensor that could cause this fault?. Checked all fuses.

Most likely culprits are the PMD and the CPS. Crank Position Sensor is on the driver's side, down by the bottom pulley.

I tried a new (known good) PMD with no effect. I will check the cps. Thanks.

"Getting fuel to IP (loosened line and get fuel when key in run). "
A 1995 doesn't run the LP in the "run" position only "crank" position unless there is oil pressure. Check the battery connections on the drivers side battery and at the fuse/relay connections. The ECM is feed from the drivers side battery the starter from the passenger.:)

I was remiss in not mentioning that the LP was wired to a relay that closes when in the run position. I assume this was a quick fix for a faulty OPS.
