Testing AEM / LS coils?
I´m trying to figure out if my coils are broken. I have the AEM coils. Car was running the other day but I flooded it this morning. Checked for spark with a timing light on all 4 plugs and also on 4 other plugs I had laying around. No spark.
These kind of coils have been giving me problems in the past so I would like to test them to make sure they are good. Is there a way?
Thanks

It’s highly unlikely all the coils went out at the same time. More likely either not receiving the trigger signal from the ecu or battery source power with the AEM coils. Those should be verified first regardless. Did you check the fuse(s) and relay(s) for them? The grounds are very particular on those coils, but probably not the likely culprit.
Is this a kit from Sakebomb, etc. or homemade?
Otherwise when everything is working properly a simple HEI tester will help diagnose weak spark wires and/or coils
