Fugu Posted July 20, 2007 Share Posted July 20, 2007 I am on blackberry bear with me my friend is stuck. 02 1150rt just died on hiway. Found a quick connect loose- re connected- injectors now getting fuel, injectors sparking, side stand and kill switches operating ok. Still no start. That's plugs sparking- this happens techclusion on or techclusion off. Pulled alt cover- pulleys tight, got any other ideas? Bike only has 30k Link to comment
Mark K Posted July 20, 2007 Share Posted July 20, 2007 If you're getting fuel, it must be spark. Was it wet? There seems to be a rash of HES failures lately. Link to comment
Fugu Posted July 20, 2007 Author Share Posted July 20, 2007 Not wet but injectors spraying- looks like lean spray but we are not pros may be fine. If hes was culprit how would there be spark and fuel spray? Bike is a couple hours east of salt lake city- no west sorry- west of slc+ another friend on the way to get it and haul it to motorcycle r and r tomorrow- try to save the trip agaqin- first somebody hits this bike and he has to get a sidecase in a hurry, now it dies no reason Link to comment
Fugu Posted July 20, 2007 Author Share Posted July 20, 2007 Is there some trick to priming the injectors after fuel line disconnect? Since pump is in fuel I figured should be simple- turn on and crank it? BTW- as proof of how cool r and r is- turns out one of the local numbers in bmw anonymous is one of the guys there. He called me back- talked to his wife because he was out and when he got home he called me to see if he could help To be fair every anonymous number that was home tried to help but i do not think the rest work at shops- O well pizza and beer time- nothing else i can do hours away hopefully bike gets going tomorrow and they can catch up w me Link to comment

Bike only has 30k Fugu, I presume by the time you read this you have already been rescued? If not, pull both spark plugs & snap them back into the plug wires,, then lay them on some metal part of the frame or engine & crank the engine with the ign switch & kill switch turned on.. You need to see a bluish colored snappy spark jump the plug gaps.. If not, look for wiring issue (or NO power) going to the coil, bad HES, or other ignition failure.. With the spark plugs still out & the ign & kill switch on & side stand UP.. Turn the engine over using the rear wheel & trans in 6th gear.. If all is good with the fuel pump, HES, & computer the fuel pump should run every time the engine is turned through TDC.. You need both good fuel injector squirt & good spark to get that engine running.. It’s possible your bottom HES is working but not the top one…You need both to get both fuel injectors & proper spark.. Twisty Link to comment
Joe Frickin' Friday Posted July 20, 2007 Share Posted July 20, 2007 Fugu, I presume by the time you read this you have already been rescued?

You need to see a bluish colored snappy spark jump the plug gaps.. If not, look for wiring issue (or NO power) going to the coil, bad HES, or other ignition failure.. A spark delivered at atmospheric pressure does not guarantee a spark will be delivered through the high-pressure mixture at TDC; the extra imedance under those conditions means the spark may find another path to ground, as through a crack in the ignition coil insulation. If you've got spark (per the above-quoted test), fuel, and a properly functioning HES (click here) for how to verify proper HES function with a DVM), it might be worth trying another spark plug coil.

malibu Posted July 20, 2007 Share Posted July 20, 2007 The link in Joe_Frickin_Friday's message is relevant to testing the HES on an 1100R engine. The wiring is different on the 1150 engine. Sorry I can't offer the correct test link myself, but I know I saw it around here some time age. I will try to locate it and post it. Link to comment
malibu Posted July 20, 2007 Share Posted July 20, 2007 OK, I did a bit of checking and remember what I did when I found the wiring different on my 1150RT than what was shown in the 1100 engine HES information. I took the idea from this picture (see the attachment) and figured out which wire was which on my connector. As I recall, there was one less wire and the color coding was different, but I believe the B+ was still red. I had the electronic schematics so I was able to figure them out. Unfortuantley, I don't have that information with me now. Good Luck. Link to comment
Fugu Posted July 25, 2007 Author Share Posted July 25, 2007 My friend got back to SLC that night, the following morning Motorcycle R&R did their usual excellent work... Big Twin in Boise, ID changed the fuel filter on the bike for the PO. (In addition to losing several of the fuel pump bolts and not replacing them). Somebody didn't get the fuel line quick connect done up properly, and apparently when they disconnect w/ the bike running, and the check valve shuts off fuel flow, the pump pressure blows the lines off inside the tank. So, they fixed it, replaced the missing bolts and gave the bike the once over, my buddy caught up with us the next day by slabbing up to Boise while we twistied over there, then we took the rest of the ride as planned. Big big thanks to R&R for getting the bike in and out. It ran like a top the rest of the trip. Mine was flawless, too. Link to comment
