A buddy and I took off an aftermarket alarm system from the 87 RX7 we are trying to get ready to auto cross. We have also replaced injectors and fuel pump and got rid of the air pump and re ran the vacuum lines. Now we can't get any spark or fuel. We are running out of things to check. Have reset the ECU and plugged in a different one from another project. Any Ideas on what controls both the fuel and spark? We really would appreciate the help!!

What factory wires did you tap into? You must have cut something that gives power to the ECU, or maybe your EGI INJ fuse blew.
