    300 Promax Not Firing Injectors

    Trying to bring back to life a pair of 98 Promax 300s that have not ran in 14 years. The boat was parked due to one motor melting a wire harness? I have replaced the wire harness, and going thru the VST/fuel system, but the injectors wont fire. good fuel psi. I swapped computers from the other motor that claimed to run with same result. Both Computers Bad? Got spark.

    Double check your grounds first.
