Good Evening All,

A little back story (in short), I relocated the PCM to the fender well and the junction box underneath the dash. Lots of cutting and soldering. Simultaneously I installed a KB 2.6l stage 2, DW300M pump, '13-'14 GT500 injectors, and SCT MAF. Remote tuning is underway. Car idled for a half hour on Sunday, drove to the end of the block and back. Hooked up my electronics to datalog, dropped the e-brake, engine immediately died. Dumped codes (B2103, P0351, P0356). Cleared codes. Engine has not started since. Will crank and crank. Engine catches but immediately falls on its face.

Ordered new coils. Verified 12v to the pigtails. Ordered a tool to check spark (OTC 6589). Also, cleaned all the contacts with electronic cleaner and applied dielectric grease before ordering new coils.

This thread however, is to catalog my troubleshooting efforts with the PATS system for future reference for others. I'll be using the 419-01B-1 to assist. Definitely will be chasing down wires and taking pictures. I plan to purchase copies of the OEM Workshop manuals and wiring schematics for the 2005 year model.

Any input from individuals that have already gone through this process would be greatly appreciated. Here we go.
