Posted this in the knowledge vault also as I couldn't locate similar symptoms during a search. Have not run my Ulysses in about a month, so I go to start it and the battery is totally dead, reading 0.41 VDC. So take the fully charged battery off my wifes sportster and try to fire it up. The motor turns fine but will not start,the check engine light does not come on for its initial 4 secs and the fuel pump is not cycling,all fuses checked good. It was running fine when I put it in the garage,I'm leaning towards the ECM but why would that draw down the battery also | ||

There are several trouble codes for the ECM. I would try to pull the codes manually (without VDSTS) if the system has current enough to give you a code. I do not recall all that the main relay powers up but I know that the second relay is for the two aux 12vdc power points. I would switch the relays around to see if the main relay is at fault. Maybe someone with a wiring diagram will chime in. My manuals went with my Uly. | ||

Thanks Davo, I neglected to mention that I had switched relays around and I can hear them operate when I cycle the run switch | ||

In order to retrieve trouble codes w/o software: Get a short piece of 18 ga. wire about 12” long with two small insulated alligator clips. The manual uses part number 72191-94 (two of them) as end connectors instead of the alligator clips. Go to the data link connector that is located on the left side just under the edge of the seat. Remove the rubber insert. There are four pins inside. Looking at the connector with the locking hasp pointed down. The pin orientation is such that pin # 1 and pin #2 are both on your left. See below: #2 #3 #1 #4 lock With the key and ignition off, connect pin #1 and pin #2 with the home made jumper. Make sure you do not touch the other pins! Then turn the key and the ignition on. Do not start the bike. The engine light should start to flash: If it flashes many times (about 10 or 11, to fast to count for me) very fast, then there are NO trouble codes. Otherwise there will be 6 quick flashes at 3 per second and this is an intermission. Then there will be a 2 second pause Then count the number of one second flashes separated by 1 second pauses and this will be your first digit. Then there will be a 2 second pause Then count the number of one second flashes separated by 1 second pauses and this will be your second digit. Then there will be a 2 second pause Start back at intermission of 6 flashes…………..and so on…….. This will continue until you turn off the ignition and the key and remove the jumper. If you remove the jumper without turning off the ignition the engine light will continue to cycle trouble codes. If you have a trouble code and then you correct the problem that created the code. The bike will automatically clear the codes after 50 start and run sessions of at least 30 seconds or more. Until then the code will remain even if the problem is fixed. Trouble code list: 11-TPS 13- O2 sensor 14-ET (engine temp) 15-air intake temp 16-battery voltage 21-exhaust actuator 23-front injector 24-front coil 25-rear coil 32-rear injector 33-fuel pump 35-tach 36-fan 44-bank angle sensor 52, 53, 54, 55- ECM failure 56-cam sync. Failure Good luck. There is a more detailed account of this procedure in the shop manual. There is also flow charts to correct all of the fault conditions. This procedure has pulled codes that my VDSTS Pro USA did not pull. The VDSTS could clear them but it could not recognize all of them. I never leave home without my jumper wire, list of the codes, small box of fuses, electrical tape, and an extra relay. I hope this helps.! | ||

Also, try to get the fuel pump to cycle by putting the UlY in a high gear and push the bike with the ignition switch turned on. The fuel pump should cycle. | ||

This may be 2 separate problems. The discharged battery may be just a bad battery. There were some previous threads regarding broken wires at a splice in the main harness near the front of the steering head. There are also 2 ground wires that attach to the steering head behind the headlamp assembly, which may be broken from the left headlamp boot rubbing and flexing these wires. There are also other problems reported on the "77" connector. http://www.badweatherbikers.com/buell/messages/142 838/335450.html and http://www.badweatherbikers.com/buell/messages/327 77/246851.html Hope this helps | ||

Well, I tried to pull codes from the ecm this morning,unfortunately no luck.Checked and double checked all fuses and switched around all relays in every conceivable combination. Have power to the ecm across pins 1(+) and pin 2(-)at connector #10.According to procedure 4.12 in the service manual it looks like the ecm.Oh well, I guess its dealership time. This is actually the first problem I've ever had with this bike after 18 months ( its an '07), I guess my luck just ran out. Thanks to all, especially Davo. | ||

I had the same problem with mine last summer. The engine light would not come on and the fuel pump would not cycle. It would crank over all day but not fire. As it turns out the ECM had a small crack in the bottom of it. | ||

Well,after four days at the dealership, they figured it to be the ECM. Now just another week to wait till they get one in. | ||

Wow! Mine was in and out of the Medicine Hat Alberta Dealer on the same day. I though us Canadians got the shaft when it came to service. | ||

Unfortunately I live in Louisiana,so if I wanted some Harley clothing or an oil change I might get it in one day. | ||
