powewrgrid

i have a mag 20 with fie crossover switch and msd powergrid. i can fire motor if i just go straight from magneto. once i hook up the powergrid i am not getting it to fire i tried a second powergrid and also another crossover switch. i tested crank trigger and extension with fie tester also tested the signal wires from the crossover switch and am getting good signal from them . the white wire that goes to magneto does not seem to be getting signal . is there something in the settings that i could have missed that could stop this

 

If you have your grid set to log data you can look at the ignition in and Ignition out which is the trigger in and output to the coil. So does it stall if you start it on mag and then switch it over? Will it not start while the switch is flipped to grid? Will it start if you take the switch out completely?
