I recently got a LS Coil kit from Nigel over at Flow Force. Setup everything up on the car and in tuner studio referencing his instructions here https://goflowforce.com/instructions
With everything hooked up the car will not start. There is no spark during cranking. I tested the harness right were it connects to the coil using a DMM to ensure I was getting 12v power and 5v on the signal wire. Everything checks out. Spark plug wires tested ok for resistance. I setup the dwell table and battery corrected in tuner studio as Flow Force has it on there website.

Hoping to get some guidance, I am not sure how to start troubleshooting this issue.

You can use the output test mode in tuner studio to check each coil for spark. In order to test a coil, take out one of the spark plugs and connect it to that coil. Put the plug somewhere on a bare metal surface on the block such that it's grounded. Go into output test mode in Tuner Studio, and test spark A and B one at a time. A should fire coils 1 and 4, B should fire 2 and 3. See if you have spark from the correct coil output in MS.

Did you ever find a fix for this? I am having the same issue. Just put LS coils from flowforce on and now my 97 won't start. I have triple checked all wiring and grounds. And all settings are correct in Megasquirt per flowforce instructions. Im not getting any spark.

Was a wiring issue from the person I got it from. I think he is the guy who started flow force.
