Not exactly Mustang except for the engine and ECU wiring harness. I have a 1992 Ford Ranger 4x4 with a 1989 HO 5.0/GT40P heads/Explorer intake using MSPNP2 ECU. It was running fine with the stock distributor and TFI. I already had the Explorer FEAD on the front of the engine and that made it easy to install the EDIS 8 CPS. I completed all the wiring and attempted to start--nothing. Changed the polarity on the VR sensor--nothing. Changed the VR sensor and got some fire but not running. Finally went over the wiring again and decided I had the A/B coil mis-wired, so I swapped those and it started and ran horribly like it is on 4 cylinders. Won't idle. Swapped out the C/D coil today because I broke the connector on the coil. Tried to start and just got some backfires through the intake. I attached my log from it's short run. It is advancing the timing, so it must be getting SAW and PIP? which would mean the VR sensor is working. Any ideas?
