Author Message   Drhodes1970 Posted on Wednesday, October 13, 2010 - 11:41 am:        Last night coming home from work my FL and CEL came on so I stopped and got fuel. It wasn't low on fuel. Another mile or two down the road it came on again for about a minute then went out . It did this a few more times. Anyone have any ideas I haven't checked diagnostics yet.   Boogiman1981 Posted on Wednesday, October 13, 2010 - 11:44 am:        new IC   Zac4mac Posted on Wednesday, October 13, 2010 - 11:53 am:        Sounds like the sensor, was it pretty cold? We had our first frost last night. 2 Scenarios possible - LFL/CEL at start-up, goes out near reaching OpTemp - old firmware in IC - Replace IC LFL/CEL come on AFTER reaching OpTemp, goes off after engine heatsoaks frame and warms fuel or doesn't, depending on how low ambient is. Sensor out of range - replace fuel pump/sensor ass'y. Once you know the sequence to reproduce the DTCs, take it to the shop for warranty diagnosis/repair and let them know how to reproduce the failure mode. <edit> I should add, the sensor is a thermistor, so this error is exacerbated by colder ambient temps. Before fixing mine with a new fuel pump ass'y, I had issues thru the Winter, went away and behaved thru the Summer, only to return in the Fall. An annoyance only, rideability never suffered.

The bike has had a new IC put in at Zac4mac's shop earlier this year before I purchased it. It is the new firmware. Not sure if it came on at startup or after reaching Op Temp, but they did go off after a while.

Fuel Sys Error at startup went out after reaching temp.LFL and CEL stayed on the whole time.   Drhodes1970 Posted on Thursday, October 14, 2010 - 01:48 am:        Oh, Yeah. Thanks for responding guy's.   Ausxb Posted on Thursday, October 14, 2010 - 02:10 am:        You need whole fuel pump assembly replaced to fix it apparently   Smoke4ndmears Posted on Thursday, October 14, 2010 - 02:32 am:        Mine did this. New fuel pump needed most likely. It doesn't affect the running of the bike fortunately, its just a wonky signal from the defective thermistor.   Drhodes1970 Posted on Thursday, October 14, 2010 - 01:56 pm:        Thanks. I'll relay this info to my dealer. I really appreciate the help.   Rpm4x4 Posted on Friday, October 15, 2010 - 12:23 am:        With the stock ecm the LFL will come on briefly on start up but with the Erik Buell Racing ecm it does not.
