multiple issues fuel and direct fire
Im working on what has been a 2 year project. I have taken a 93 rx7 that was essentially a bare chassis and have it to the point where I am trying to start it.
First problem was the ignition switch not sending signal to the starter. Im currently waiting on a new ignition switch but wired it to a push button for the time being so it works.
Second problem, the fuel pump is not getting power to the white/red stripe wire. There is power to the smaller gauge wire next to it however. I started at the ignition switch and power goes to the fuse which is good and has power on both sides. I bypassed the resistor under the master cylinder and still no power. I have swapped out both fuel pump relay on the front of vehicle and next to main ignition and nothing. I tested for 12v at both relays with them removed and there is power to the smaller gauge wires but not to the larger gauge wires. I jumped power from the smaller 12v on the very front relay to the white/red stripe and I get constant power at the pump. Any help is appreciated.
My second issue is no spark on the aem coils. I have the sakebomb harness. I have power and a good ground at all the coil connectors, but I don't seem to be getting a signal. I have it hooked up as stated in the instructions, and have cut the jumper wire, and ran the blue/orange wire to the diagnostics box, and also ran the wire to the map sensor as stated in the instructions.
I wonder if the two issues are somehow related. Any help is appreciated on these.

Alot of views with no responses......I guess I'll pull the fuse block and see why the power isn't getting through firewall
With this issue, you wouldn't want someone to respond unless they really know what they're talking about. That being said you could do the fuel pump rewire triggered by a separate relay to bypass the red white wire.
I'm not familiar with the Sake bomb setup so I won't comment on that.
