[QUOTE="Riddick, post: 16469307, member: 143188"] If you pull a coil with a spark plug in it you should see a spark as long as you ground it. Best way to do this is to place the electrode right next to a grounded bolt, as you're cranking you should see it spark. You should not need a reflash unless you put in a new ECU. If you are using the same ECU as before it should work fine, its married to the car not the engine. Sent from my Moto Z (2) using Tapatalk [/QUOTE]
