99x1, no fuel, no spark, getting voltage to coil, just no signal. no signal to injectors. 56psi fuel pressure. replaced ign pickup, coil, tried another ECM, tested soo many wires its ridiculous. wiggle tested everything 199 times. so now im headed down to harley to get a new bank angle sensor. if it doesnt fix it, im at a loss. is there anyone out there that can help me at all???? |

crank position sensor wire had a break in it. when i pushed in on the pin with a voltmeter, it made a connection and tested good, but when released created an open in the wire. |

Ouch, those type opens are very tough to find. |

Dan-
Did you get a code from your problem? Here's what I've gone through with my '99 S3 that started surging the runs terrible.
So far no luck but I think I have it narrowed down.
1) Compression test - 130#ea. - ok
2) Replace intake seals
3) New spark plugs
4) New fuel filter
5) Fuel pressure - ok
6) Check all connectors - ok
7) Check plug wires, coil, spark at both plugs - ok
8) Head temp sensor - ok
9) Reinstall stock ecm - same problem
So it still runs like crap so I start it up and check each cylinder head temp with temp gauge, hmm, front - 140deg, rear - 210deg, check exhaust pipes, same results.
I'm thinking maybe I have a bad injector. |

Mike, O2 sensor could be belly up. It controls low-mid operation. |

Dnchevyman, did you get a trouble code/engine light? I have been trying to figure out my similar problem for weeks now on my 99 x-1.
Cheers,

Mark,
List what you've done and maybe we can give some insight. Since I wasn't getting any codes I started with the easy & cheap things first. I figured out it was the front cylinder when the head & pipe wasn't getting very hot when it ws running. After I put a spare plug on the front wire with a ground lead attached I could see a spark so I figured it must be the injector. I then cleaned them and it worked for awhile then acted up again. I swapped front to rear and the problem went to the rear so I knew it had to be the injector.
Ordered new ones, $66/ea. so I hope I made the right diagnosis and should know Monday after they come in.
I had already gone through most of the connectors cleaning and greasing them. Didn't find any broken or frayed wires, just a couple of connectors with a little corrosion on them. |

So why is it that when the bank angle sensor goes bad it doesnt flash a code? Pulled the BAS and the bike fired right up. Thanks to all for the help.
Cheers,
Mark |

That's a good question, Mark. Wouldn't it be nice if there was a simple description available of how the EFI software interacts in general with the rest of the vehicle, moreso than what's in the FSM? |
