Fuse 28(under hood) PCM 1
I have a 2003 TB EXT and I can't figure out why I it occasionally blows fuse 28 PCM 1. It has been about 1.5 months since the last time we had this issue but it is kinda difficult to trust it in this situation. I have tried unplugging the fuel pump relay, fuel injectors, coil packs, O2 sensors and range/selector mechanism. The last time it blew the fuse I noticed the shift interlock solenoid was no longer functioning. A few days ago I went out to try working on it again and the keys were stuck in the ignition. I decided to replace the ignition switch and that didn't do anything either. Anyone have an idea of what could be happening? Is the shift interlock system tied into the PCM 1 circuit somewhere? Thank you in advance.
