Please excuse my total lack of tuning knowledge.I am running a coil on plug setup on my car with a twinfire.I am also running a full Mil spec harness.I need to figure out how to make sure the twinfire is working properly.The car turns over fine and gets fuel but it doesnt start.I have had this issue a few times in the past.A few times it was a bad twinfire and once it was a fried output/channel on the ems.The mil spec harness is whats going to be the pain.I have no way of removing the wiring to check the twinfire in order to check it as per AEM's insrtructions.I just wanted to ask if yoiu guys have any ideas on how to check it.Thanks

 

Remove the plugs from the engine. Unplug your injectors so you wont flood the engine. Put the spark plug back in the coil and ground the strap to the head. Crank it over and look for the spark on each cylinder. Just be careful cause you DO NOT want to be shocked by your ignition system.
