We need a working link to your video. I searching "Richard Wong Nautique" and YouTube served up the following, which is entertaining but not necessarily helpful: http://youtu.be/5WW1zSuV5Yo" rel="nofollow - http://youtu.be/5WW1zSuV5Yo |

Seems to be a fuel supply problem. I'd check: 1.) Your safety lanyard. These control the fuel, not the starter motor or ignition. They cause more problems then you think. Even if it's on, fiddle with it a bit to see if it might be faulty and causing problems. 2.) The Fuel Control Cell (If you have one) there is a little piece of tubing in there that can crack and cause problems 3.) Relays. The Fuel Pump relay, identical to the EEC relay, can cause problems. Hopefully others will weigh in as well. Let us know what you find. Also, read some of the threads here: http://www.correctcraftfan.com/forum/forum_posts.asp?TID=25584&PN=1&title=poor-mans-gt40-diagnosis" rel="nofollow - http://www.correctcraftfan.com/forum/forum_posts.asp?TID=25584&PN=1&title=poor-mans-gt40-diagnosis |

Is the fuel/gas fresh and good? When the low pressure fuel pump on my excal was failing the symptoms were very similar. |

* it ran strong few minutes backward on the ramp for removing the boat to water because the trailer and boat stuck on the ramp, then the issue occur when flush the engine . * find the gas finished at the moment,than fill it up with new gas. * suspected Lanyard and checked, open current of the lanyard is 45ma on DVM,is this right ? * Both low and high pressure pump are running,so can get gas strong fire out from the injector rail test point. |

You want to check Ohms and not ma. You should get a near zero Ohm reading. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| when the lanyard put in place, its zero ohm,when not in place I measure the current to make sure the loop is not open. |

| got a OBDII scanner from China, but can't find the right connector for the GT- 40, seems they are unify to a standard type but different from GT-40 used in Nautique, how you guys connect it to the STO of GT-40? or any one know how to modify it? |

lewy2001 is our resident gt 40 expert. If I recall correctly I think http://www.amazon.com/INNOVA-3145-Ford-Digital-Reader/dp/B000EW0KHW" rel="nofollow - this is the tester,he will know for sure. I also think you need the extension cable too. If he sees this I know he will weigh in. I don't know if you have seen http://www.correctcraftfan.com/forum/forum_posts.asp?TID=25584&PN=1&title=poor-mans-gt40-diagnosis" rel="nofollow - this either it may help oops I see Brian already posted that  ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Yes Gary that is the correct tester for the GT40 OBD1. You dont really need the extension cable. Hard to get a handle on the problem from that video. My first thought was the lanyard but then I heard it idle for a longer duration. I did hear a hissing noise maybe take a better video of the problem if you can enlist a camera person to help. Fuel pressure check is your next step and if you get the code reader this little video may help. ------------- If you're going through hell, keep going http://www.correctcraftfan.com/diaries/details.asp?ID=2999" rel="nofollow - 89 Ski <a href="http://www.correctcraftfan.com/diaries/details.asp?ID=5685" ta |

Congrats on finding the problem Richard, I'm going to add this one to the thread. Jon, you might want to start a new thread as your 79 tique has totally different fuel and ignition systems from a GT_40, although the antisiphon valve is one commonality. |

| the breaker on the kick board beside the toggle switch always stripped down when start the engine that misleaded me a while when trouble shooting ,that controls the fuel pumps,. |

update: the issue finish ,finally found the connection wire blue/orange from ECM pin52 to fuel relay pin86 have serious intermittant,that is the reason why fuel pump some times don't run and the breaker striped , make a new wire to connect it, it start every time ! |

| update: the issues: fuel pump and starter intermittent cause by a connector found under coolant tank ,its design don't water resist, many salts build up ,clean it every thing become fine. |
