[QUOTE="Arnoldb.1, post: 1540159, member: 30179"] Aight been a minute, but had a rear axle issue and had to rebuild it, so I finally did the wiring test per alldata, found nothing really, except when doing step FJ11 Battery ground and pcm test pin 48, it wouldn’t read resistance, would only flash it for a sec on the ohm meter. Makes no sense, cause it says if ohms are below 10k repair short but pin 48 in the pcm goes directly to pin 4 on the IDM and nothing splices into it. FJ12 check is for short to power, and ask to voltage check same pins with key on, I had voltage on both pin 48 and 95 on the PCM, say to repair short but again no clue what causing it other than something in the IDM. Cause the two pins single wire directly into the IDM plug nowhere else. I am running the truck and did test without the hydra chip. Truck starts right up without hard cranking like with the hydra.
