I have come here often and found answers to my questions but I cannot figure this one out so I thought I would post a question.

Last time in the lake my boat started smelling like gasoline. I took it home and didn't touch it for about a month. When I went to winterize it I could not get it to start. I winterized it and left it for the winter. Now I am trying to get it ready for summer and it will not start at all. When I mist gas into the throttle body it starts and will stay running as long as I am spraying fuel into the intake. I have 40psi of fuel pressure. I have a brand new battery with 880 CCA. I checked the injectors and they are getting 12V to them when I turn the key on. My thought is that the ECM is just not firing the injectors. What makes the ECM fire the injectors? I am also gettting rpms showing on the tach when I crank it. I looked for a crank shaft postion sensor but cannot find one. Is there a canshaft postion sensor and if so where is it?

Thanks for your help in advance.

:welcome: to iBoats . . .

Post up the serial number of the engine for the best answers. Sounds like something common to the injector wiring (not an expert in that area, but you can probably Google some info while others respond)

Thanks for the response. The serial number of the engine is 0L391284. I have searched a long time both here and google and not found the answer to my issue.I am hoping someone here can tell me what fires the injectors.
