I figured the IAP was a false reading. CAT offers a plug kit for the HEUI pumps and a graph that shows which plug is longer or shorter than the current one. By dead heading the pump you mean to cap the outlets from the pump and tee in a pressure gauge capable of reading 4500 psi min?

I have an 836 Landfill Compacter SIN# 7FR00315 that will not start. Intermittedly it will start however completly random. Checked speed sensors, changed IAP sensor and IAPCV, checked engine and ECM harness' for moisture and wear. Have installed different compensator plugs. While starting "Disabled Injection" appears in the status flag section of CAT ET. Only active code is throttle lock lamp current below normal. While cranking; engine oil pressure according to CAT ET varies around 7-9 psi. IAP stays constant at 256 psi. Ground Level Shutdown Switch is working correctly and is off. Any help would be appreciated.
