Could a P1351 be a False Code? (older GM trucks and vans)

From our research, this P1351 "Ignition Control Module Circuit Voltage" ( we had a misidentified description, of the code definition on our scanner) can be set, simply, from ANYTHING that causes an extended or long crank time. So be careful with the flowchart on this one, as it only mentions the ignition module, related wiring or engine computer faults as the cause of this code. Low fuel pressure, injector issues, flooded conditions etc., causing extended cranking times, WILL also set this code! Special thanks to the owner (name unknown) who is a viewer here on this channel for giving us a chance to look at your truck.
