I picked up this bike to work on 05 f4i it started nd ran was goin good then one day it started at 6 am went to sleep woke up 11 am nd the bike didnt want to start i rebuilt the fuel pump
i replaced the zener diode only thing weird is there was never a bank angle sensor nd ion see it spliced anywhere nd it was running now it jus cranks with no prime ive jumped the fuel pump with a battery nd primes nd thru the fuel relay any ideas

 

It could just be the kill switch, they do have a reputation of failing due to weak solder joints.
