I have an 02 XLT AWD/4x4. It has been a daily driver for 8 years with 230k on it. It began with random misfire according to OBD and flashing SE light. I checked all the normal electrical and catalytic converter. Cleared code, the P0305. Back to garage, noid light on it, no power from ECM and truck wouldn’t start, just crank. Tried connecting to the OBD and got a link error. Checked battery, replaced battery. It will crank, no power from ECM to COP’s at all, still had link error to scanner. Checked for ground fault (pulled - terminal an Hooke test light between terminal and post to see if it blinked) and every fuse checked. No luck so far. Any thoughts? Have I lost the ECM?
