      Andre beat me to it. The thread below was just posted in the electrical forum, this person is having trouble with their fuel pump not priming.



      Probably another connector issue for that person and it might be your issue as well. Although I'm not sure if that explains the whole rough running issue, maybe that was from the CPS. But then you ask the question, why would the CPS fail during winter storage??? SMH

        If you get a new connector the green wire is not used. Just coil it up and set it aside. Used to be for anti static? but was discontinued according a product update by the engine mfgr.

          Thanks for the links to the posts, will definitely be checking the connector after work. Yeah I have been scratching my head on why it ran after replacing the CPS's and then stopped, or why the COS's would randomly fail after winterization.

            Is this this connector then? I read the forum and this is the part number someone said they used. This connector does not have a green wire though?

              Here is the two I had problems with. One plugged into the module, the other plugged into a female plug. Ignore the wire nuts and splices, that was marina work. The plug into the module had a pin somehow pushed out. The plug in the middle of the picture had somehow had the pins spread and had some corrosion.

              On a side note I had to continue to work on this and found some more of this kind of quality work in the harness buried inside of the plastic wrapped wiring. Have to rebuild that part of the harness this weekend. So look for signs that someone has tampered with it. electrical tape is a dead giveaway as is any kind of butt connector etc.

                Of course it starts in my driveway. I was going to check fuel pressure then try and replace the pigtail connector to the fuel pump. The pigtail connector I got at autozone is too big and not the correct one anyways. I checked the three connectors shown in the picture and all seemed to be okay as far as not being corroded or having disconnected wires/pins. Difficult to see inside the connectors though. Didn't leave the engine running long since it wasn't hooked up to water, but seemed to be idling a bit rough.

                  In your picture the one on the left and the one going into the fuel pump are the two you want to pay attention to. Take a pick or something skinny and bend the tabs so that you have great contact between the female and male. You could have a bad ground as well where it touches the block, but I would start with the connectors since you plugged and unplugged them and the boat fired up

                    I actually removed the black connector and spliced the gray and black of the pump connector directly to the wiring loom. The black connector would get hot and the pump would shut off. Try using a pic pin in the female ends of the pump connector to tweek the parts to make a better connection if you can't find a connector.

                    You should also get a 5 gallon bucket and a piece of 1 1/4 inch hose so you can test this on the trailer. It will save you a ton of time. If it starts just keep the hose running in the bucket.

                        I took it to the lake last night. Started right up and left it running on the trailer for about 20 minutes with no issues. Seems like replacing the crank sensors fixed my original problem, but I suspect I still have an issue with a bad or loose electrical connection somewhere.

                          hmmm ok. you didn't drive it though? Curious to see if it is running rough under load.

                            Took it to the lake finally last night and ran it for a couple hours without any issues. Sucks to have it in running condition August 1st, but still some time yet this year to use it. Thanks for everyone's help!

                              For anyone that might be having the same issues with their boat, I had to have additional work done. I was able to run the boat twice on the lake before it died again, and I couldn't figure it out. I took it back to the original service shop where it sat for three more weeks, only to have them tell me it was likely a loose electrical wire, but ultimately they couldn't figure it out and I'd have to pay them for their time.

                              I took it to a different shop about an hour away. Despite being busy with winterizing boats they called me less than a week later to tell me that the IAC (idle air control) motor was bad. It was almost $400 for them to order the part from indmar which they did. They replaced the IAC and spark plugs at the tune of $750, but noticed that the engine temp was not heating up. They checked the thermostat and it was stuck wide open, so the cylinders were being fed too much fuel which was fouling the spark plugs. $900 later I have a new IAC, spark plugs, and thermostat. After doing some research it seems like all three of these are fairly common, and the parts are easy to source from local auto parts stores for a fraction of the cost. Just thought I'd update this thread for anyone that might have the same issues as I was having. Nothing like having your boat finally ready to run in October in Iowa.

                                thanks for following up on the post.

                                How did they come to the conclusion that the IAC was bad? Did they say that was a regular item to check, and how do you know if it is good or bad?

                                What I get from this is check the fuel pressure, fuel pump, IAC, and CPS for any symptoms like yours. I know how to get the others at this point, just not the IAC.
