Found this posted by Raylar ( 496 guru):
"If you have an active fault code or a problem with a cam sensor fault it can take the motor longer to start and if the cam sensor circut is bad it sometimes won't start at all." See post # 4 of this thread: https://www.offshoreonly.com/forums/...-pressure.html It's still not clear to me if a bad cam position sensor circuit prevents ign or fuel inj or maybe both?? Wouldn't hurt to check the wiring for it. You may be able to find what the proper resistance range is for it online somewhere. |
Ok so I borrowed a scanner and these are the active faults I have.
Pitot ckt lo Fuel level ckt 2 h Steer ckt h trim ckt lo |
Are there fuses located on the engine. I have checked all fuses on the fuse block on the boat behind the steering wheel
also where is the crank and cam position sensors located |

After doing some research I agree but it still won't start. i guess I'm going to swap out the crank and cam position sensors and hope for the best

Need a serial number or at least a year of the motor? Measure voltage on pin D of the DLC connector, should see 12V with key ON and while cranking Disconnect one of the injector plugs and measure voltage with key ON When cranking listen for the fuel injector ticking |
Have you put your fingers on the starter selenoid wires,, my friend went thru this,,same engine as yours,,spent $1500. at 2 repair shops,,still would not start,, finally found a boat mechanic that knew what to look for,, a loose wire on selenoid,,fixed in 39 minutes.,,,just sayin don't overlook the easy things first,,,good luck.

The serial number is 1a059707
when I have the key on im getting voltage and with a testing light it pulses when being cranked. And I don't know which connector is the dlc |

when I have the key on im not getting any voltage at the fuel injector but I shouldn't be unless the motor is cranking over and the computer is commanding it as the engine is rotating and the injectors are pulsing to let fuel in. And I don't know which connector is the dlc First check fuse with a volt meter, then trace it back to the connector |
