One of the first things I always check is fuses. Could be as simple as a fuse is out. Conversely it could be the pump relay has gone bad.... could be a bad pump. Start with the easiest .... fuses......and work up from there.

 

Thank you.checked fuses good,pump good.started checking relays with key on no prime.no power to selonoid valve relay til bike starts.gonna replace selonoid valve relay and if that dosent work going to try on off/kill switch.Thanx,Joey G

 

If all that is good, then it must lie in the ignition circuit.... and very well could be a switch.... there are three that can be pesky.... side stand switch, neutral switch, and the kill switch. Could be any one of them that might cause an issue. Could jump them one by one and see if any of them fix the circuit.

 

Three switches you can check that are all part of the ignition/startup circuit that have been culprits for many in the past are the kill switch which you are going to check, but also look at the neutral safety switch/relay, and the sidestand switch. All 3 of those are part of the circuit. I have had sidestand switch go bad as well as neutral safety switch. Easy enough replace and even easier to check... just pull the leads and jump the wires one switch at a time. If it is one of them, jumping the wire will let the circuit energize.

 

Gonna give it a try wiring drives me nuts .Thanks
