Hello, my name is***** sounds like your PCM may have failed which can cause coil to short out. Check to see if white/pink wire is shorted to ground. If not with vehicle running check to see if white/pink wire pulses ground signal on/off, if signals stays on then PCM needs to be replaced. If white/pink wire has ground unplug PCM to see if ground drops, if not run new wire betwen coil and PCM. Here is a wiring diagram to help with testing, let me know if you have more questions. Thanks.
No problem, let me know how it goes or if you run into more questions. Thanks.
