Hi all,

I have an 85 k100rs that has been ok till now. Riding along and felt something knock between my legs like a slight vibration. Bike coasted to the curb and would not start. Thought it was the loose plug on the COMPUTER ECU ECM CONTROL MODULE BRAIN BOX and unplugged and re plugged it in. Have had this happen in the past. Put a zip tie on it to hold in position. Tried again but no start. All seems fine, starter cranking, battery power ok, gas in tank. Could it be the fuel pump relay or the pump? And how do I figure out which one? http://www.bmwmoa.org/forum/images/smilies/dunno.gif
