I have been using this forum over the past few days to try and diagnose and fix our 2002 Centurion Elite V with a PCM 330. Long story short, my dad bought this boat new in 2002 and we used it almost daily during ski season until around 2014. At that point the boat boat started having issues running consistent. Fast forward to 2016 and no real progress, in and out of the shop, lots of failed lake days and tows back to the dock, my dad gave up, basically refused to spend any more money on it and threw the cover on where it has sat until last week.
I decided to start working on the boat to get it back to its former glory, this is where we are today:
replaced all relays
checked fuses tested fuel pump (both)
new distributor cap and rotor
changed oil and filter
After all this, I cannot get the boat to idle or run on its own. I can pour some fuel down the throttle body and it will fire on what is there, but will not fire on its own. I have pull the fuel rails and checked the injectors. I can hear the IAC moving when the ignition is turned on.
What am I missing? It almost seems as though the injectors are not giving fuel to the cylinders. The only cause of that would be the ECM. But the ECM is working in some capacity to be able to control the fuel pump and IAC.
What am I missing? Any help is appreciated.
And yes, I checked the safety switch, it is functioning properly. The engine will not even power when it is disconnected.
