RX7 Starting Problems

Had an issue with the FD not starting recently. I don’t think it could’ve been the starter or the battery because they were new. Voltage was good. Everything on the car turned on and the engine would turn even when you push start it but would then cut off so it had to be something in the ignition system. After some research on the forum a common problem was a relay in the oem security system. Bought a new relay and that didn’t fix it. Then made a jumper wire to bypass it and it fired right up.
