Yeah, I was thinking the same thing. I started to pull off the wire harness today. gonna check it for any shorts or broken wires, thank you.

Hello, new guy here. I'm sure this has been covered several times. I tired to find some threads on it, so sorry if this is a repeat question. 2003 Chevy Silverado, cranks but will not start. P0335 code for crank sensor stored. replaced crank sensor and still no start. Found diagnostic flow chart on Alldata. performed diagnosis. removed crank sensor and tested for voltage at all 3 wires. found low voltage 3.1volts at connector. Diag flow chart says it should be at battery voltage at the Reference high signal wire. Removed PCM and Tested for power at wire and had the same voltage 3.1 volts. tested all fuses and relays all check out ok at this time. Replaced PCM with a reman unit and still have the same voltage. at PCM and crank sensor connector. I am not getting any spark signal or injector pulse. I did test all power wires coming into the PCM all checked out ok. I also checked all Grounds at the PCM, they all showed good continuity and low resistance. I have not visually checked all the grounds yet. Anyone have an issue like this or point me in the right direction, would be greatly appreciated.
