I have a 1999 mercury grand marquis with a 4.6 in it that keeps burning up the #1 ignition solenoid. I've replaced the crank position sensor and the pcm and the solenoid is still failing. all wires tested good. help!
are you talking about the #1 ignition coil? if so did you replace the spark plug and boot also did you put the bolt back in to hold it down
Have you checked or replaced the number 1 spark plug?
Have a 1999 grand marquis...when you connect connector to coil it burns it up...
