Thanks to all for the help. I haven't managed to fix it yet but I have discovered that the previous owner has performed the "nutter" bypass meaning that the non functioning stepper motor, sensors, etc are expected. Ahh the joys of buying a jeep from the son of the mechanic who lives in California, rust free but the son knows nothing about the jeep, what's been done, etc. I've managed to get the jeep home so now it's EFI, new ignition, and engine rebuild time. I'm sure I'll ping you all from time to time and I'll post progress pix I go. Looking forward to really "getting to know" this jeep.
