    Re: Ecu trouble

    I'm trying to add a pic but I guess I can't because I'm on my phone. It's the block like a harness on the black box with the ECU? Grey plug? Because in the time I've spent messing with it, I seem to only remember the wires leaving the air box, connector at bottom of air box, into a lot of wire all the way to the black box.

    There should be a connector like the grey one with all the grounds. Probaby in the airbox with the throttle bodies.

    Re: Ecu trouble

    So I've been running the jet ski. When I took it to the dealer, he pulled codes for TPS, air pressure, engine temp, air temp and pulser all at 76.97 hrs. I took ski to the lake couple weeks ago. Ran good but later in day, didn't want to start and seemed like it was getting worse. Got it on trailer and came home. Now I have diag tool so I pulled codes for TPS, intake pressure, engine temp, pulser and intake temp all at 77.37. I find it hard to believe all the sensors keep screwing up at the exact same time, any ideas what can cause this?
