PCM wiring

No, I’m not using the ballast....just power directly to the PCM. So....the ignition 1 wire (blue) has 12v when the key is on and drops to 0 when cranking (as it should). However, the ignition 2 wire (brown) has 0 with the key on, and just gets a quick burst of about 4 volts when it starts cranking- then goes back to 0 as it is cranking? I’m assuming this is not correct?

However, it still doesn’t make sense to me (even if I used those wires to power) because I can jump the PCM with direct power and I get power to the coils, but no spark and no power to the fuel pump?

Thanks again....its been very helpful as I dig in deeper!
