have an 05 hippo and it melted a coil pack on the front of the motor. one of the coil on plug types. i replaced with a used one i had changed for a misfire and it melted too. bought a new one from the parts store and left it loose, not connected to plug, to test. cuz i dont want to dig pieces of coil out of that bore again!!! turned on ignition but didnt crank and went out to feel it and was very very hot very quickly. the others were cold.
Local Bosch shop can’t get me in until week after thanksgiving. Not thankful for that... no local rover dealers... so dug in a bit more. Didn’t tear all the wire loom apart but I did get some resistance between the black and black/white stripe wire on the coil connector. Traced back to ecm and on the connector where the coils connect to the ecm I get continuity/low resistance around 1 ohm, between the black/white stripe wire and the center of the plug ”ground” wire. Does this sound indicative of an ecm failure? I checked it both connected and disconnected to ensure I was reading the ecm as fault and not the wires. When disconnected not reading continuity at coil connector. And also no connection from that center “ground“ wire to any of the other coil wires.
long story long... bad computer sound about right? if replacing do yo have to reprogram the whole car?
any help. thanks!
