Message: [QUOTE="Short Bus, post: 1447357, member: 95"] I think ive got it figured out. After reviewing the engine data on the scanner, i noticed that the vref was only 3.5, yet the map, baro and ebp readings were correct as was the EOT and ECT readings. I checked the Vref at the map sensor and it was 5v. Call me stupid, but the only thing i havent done was nail down the start circuit, i swapped relays but didnt jumper the relay or check out the coil pwr/ ground.... I spend too many days out of the year in a combine i guess. Anyway, today i jumpered terminal 30 to 87 bam it cranked over like it should. checked coil volts between 85 and 86, 12.5vdc. terminal 86 to ground, 12.5 vdc. ohmed 85 to ground while cranking and the ohms were all over the place, i think it was anywhere from 200-900. Ive already checked the pcm grounds to the battery so that pretty well points towards the pcm itself being bad unless im missing something else. [/QUOTE]
