Fuel pump comes on with ignition but shuts off after about 2 seconds.
I am not getting spark from the coil. There is a connection from the fuel pump relay pin 1 to the coil and to the RPM delay (whatever the heck that is). The more I dig into the this the more befuddled I get. I just tried a universal ignition switch using only ckts 15, 30 and 50 and the fuel pump doesn't come on at all.

The fuel pump relay turns on, after it sees a RPM signal from the ignition module.

First you need to diagnose the lack of spark. If there is no spark, then the FP will not turn on.
