I have a Ford Focus 2000 and my ignition coil pack keeps dying on me. Something is causing my ignition coil to die and its been replaced 3 times already! Sometimes it would hesitate(shake a little)/lag a bit before picking up power, sometimes the engine shuts off while driving and I would have to restart it. sometimes when I press on the gas peddle it wouldn't accelerate.
When it reached the stage where the engine warning light comes on after its been driven for awhile(half hour or so) the engine would totally stop and would not restart until I replace another coil. These strange behavior occurs usually when I am in drive/reverse mode.

In response to this problem I have replaced the spark plugs, spark plug wires and I believe the new coil is dead again cause it wouldn't start, just cranks. If anyone had this problem before or know what the cause/fix is...please help! thanks in advance!

Check the harness that connects to the coil pack, a common issue are the wires begin to break away from the connector over time and just by fluke every time u replace a coil u move the wires back into place and it works again

Do they sell that wire connector? Maybe I should just buy a new set wire connector if its not too painful to remove/install it.

Both 2000's i've owned have had 1 or more of those wires broken and it looked to be a common issue

i hope you kept all your old coil packs... they could still be good

may I ask how you check it? Just with the naked eye or with a ohm meter?

thanks

mine were pretty visible as the plastic around the wires was cracked/split. you might have to peel back some of the loom to check, but it was the exposed wires that were split

did you buy a new set wire/connector or used the old one? if they sell it I may just replace it.
