    Beeping optimax

    2009 225 opti, was doing the every 3 sec beep. New plug wires fixed that. Beeped again. New TPS and was good for a dozen runs. Now back to beeping. I have a running engine to swap parts from and did. No change, still beeps. Motor runs fine but beeps. What am I missing here? Can injectors set off the warning system? Fuel pressure? May buy a rinda scanner as a last resort. I do have several opti's. This one is a true problem child. None of the others have had any "beeping" problems. Could it be the PCU going crazy? Any ideas?

    The more I work on these opt's the stranger they become. I found a black with yellow tracer (kill circuit) wire broken at the connector going to key switch in the console. Didn't think it was the problem, repaired it and to my surprise it no longer beeps. It shut off fine and I never pulled the kill lanyard to try and test it that way. Strange ,strange motors.......This beep pattern is supposed to be a sensor out of range, but it seems to cover a range of unintended things.
