If the pump primes then a signal is being received from CPS so that is working, check the ignition amp is connected ok, you should also have +12V at the back wire on the coil when ignition is switched on. You can't really measure the output of the coil as this is many thousand of volts using a meter etc, you don't have an output at coil (Or a good one) otherwise you would have a spark, did you measure elsewhere?
