How do you determine if your pick up coil is bad Im getting no spark and have narrowed it to the pick up coil or the ign module but dont wann abuy both if only ones bad How can i check?
to save time and money the best way to find the problem is to have diagnostic test done this way here you want have any doubts if you remove the module (not too hard). auto…zone and other places like that can test it for you for free. if its good then you know to replace the pick up coil. if its bad then you know to replace the module. you can aslo test the coil with a multimeter but i would guess that you dont have one and this would be a lot more work... I like to pull a known good module from another truck, I have had gm modules pass the bench test that were actually bad, so you end up chasing your tail looking for other problems when there are none.
