2015 Police Interceptor Sedan 3.7 L AWD w/o IA "No Crank Condition"
The car started up for about 2 months but out of the blue w not crank. If you jump motive power to starter side of the starter motor relay ( terminal 3 to 5) motor turns over but of course does not start . Power to pin 16 at PCM from ignition switch, no output from pin37 of PCM to relay terminal 2 of starter motor relay. Have path to ground on control side of starter motor relay.
As far as I can determine the car does not have an IA key bod. So my troubleshooting has been on the starting system w/o IA.
Trying to determine what is preventing out[put of PCM at pin 37 of PCM, new PCM installed in May 2024 but still no output at PCM pin 37.
Looking for guidance on next troubleshooting steps to take before the car goes to junkyard.
