my 01 gsr wont start randomly like one day i go to start it and it just canks and cranks but wont start but then like 15 minutes later it will, this usually happens when it sit for awhile but sometimes not but the thing is it always eventually starts and i have replaced cap and rotor, spark plugs, ignitor, coil, main relay and it still does it so im thinking somethin with the fuel? anybody heard of this happening before?
