Check for injector pulse, you can use a noid lite, the autostores sells them. The noid lite will show that the injector has voltage and ground. If no ground look for rpm signal. Also, use a gage and check fuel pressure, some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one.
I needed to correct something, if you have good spark, there should be an rpm signal. With opti-spark ignition, there is no bypass ignition, according to my info.
