still working with this, I've checked the grounds on the intake. I've checked the EFI fuse. checked continuity across CPS. I doubt the alarm is the cause, I bought the car without a battery. Both sides of the injector plugs are hot at all times. I used a my test light while cranking to see if the light goes out on either side, it does not. I checked for any fluctuating using a multimeter, reads 0 volts while cranking with the probes on either side of the injector connector. One interesting note is the previous owner grounded the knock sensor wire.
