My dad has a 99 X1. He bought the bike after it had been sitting for 5 years because the owner died in an accident on his other bike. We had to replace the plugs and fuel pump to get it running. After riding it for a few months we decided to replace the intake seals because they had never been done as far as we know. I decided to reset the TPS using ECMSPY because as far as I knew it had never been done either. Now the bike will not start. It pops and backfires out the exhaust and intake. Sometimes it will fire for a couple revolutions or so then die. I checked the trouble codes and it threw out, 15: intake air temp short to supply or open, 33: fuel pump short to ground or open, and 44: BAS short to ground. When I bring up the live data it shows the intake air temp is 125 degrees Celsius! I turned off the BAS using ECMSPY and it seems to idle for about 2 seconds before it dies and backfires out both ends. As soon as you touch the gas it dies right out. I tried unplugging the intake sensor and it doesnt seem to make a difference starting the bike with it plugged in or not. Does anyone have any ideas what went wrong? I know I did the TPS reset correctly. | ||

Sounds like something got at the wiring harness. Mice suck and they try to set up shop this time of year. | ||

yeh, Take a close look at the wiring and connectors, mine was throwing the same 3 codes, it was the connector to the fuel tank that needed cleaning. The IAT should show ambient temp when viewed in ecmspy, i would test it as set out in the fsm to rule that out. | ||

Go back to the last thing you did--TPS re-set. If that was mucked up ,bike will run horrible,not want to start etc.Check plugs,if they fouled they are junk, and go back and reset TPS making sure you follow Al's advice.--make double sure you have it completely closed! Look and make sure you got injector leads on right injector. Did you get the injectors cleaned? Last X-1 in here that sat had to have that done along with neew fuel pump.

+1 on what FMJ said. If the bike was running fine before the seal job then you must have accidentally knocked a connector or two out of whack. A combination of codes like that definitely sounds like a bad connector. Of course a faulty TP setting does not help either. |
