Not Starting

[Chappers]

Been out on bike all day k7, came home and stopped for 20 minutes, started it then turned if it off for 2 minutes and now won't start. Pump not priming with ignition but clocks sweeping etc, newish battery so i'm thinking kill, clutch or side stand switches to start, can anyone explain how to test and eliminate these please or anything else to look at, cheers guys.

Is it turning over though?

None of those interlocks will stop the pump from priming except the kill switch if the power supply to the pump is Good ( fuses connections etc) could be the pump itself , run an auxiliary supply to the pump and see if it runs would be my suggestion before you start tearing the electrics apart ,if it runs then it will be a process of elimination but the kill switch is a possible.

Could be the ignition switch too. There's a separate terminal that powers the pump circuit & a few of us have had intermittent 'pump not priming' issues & found the contacts in the switch filthy.

Thanks for the info guys, gives me a starting point, engine turns as normal, only issue is pump not priming when switching ignition on, all else appears ok.

Is this just a case of spraying with electrical contact cleaner

You can not get to the contacts without disassembling the ignition switch. Hooli has some instructions on here.

I had this problem and cleaning the contacts solved it.

@Chappers just read through this thread - it may be that the fuse for the fuel pump has blown - note entry #4 from Speedy1959 in this thread

The thread that @Andre mentions about stripping your ignition switch is here https://gsx1400owners.org/forum/index.php?topic=6268.0

Check fuel pump relay is clicking while trying to start. Think it acts as indicators relay also, pull plug and check for dirty connectors, basics first Mate.

Thank you to everyone who has replied, I love you all  
Gonna go at it tomorrow and will report back.

Do you see "CHECK" on the dash?

If so, there is what looks like an unused connector near the the tail light - it is actually a bridge.

Pull the cover (bridge) off and clean up the connector.

Worth a try save pulling apart ignition switches, immobilisers etc.

All ok

Update, I've taken fuel pump out and tested it, it's running. 6 fuses under seat all cleaned and checked plus 6 fuses behind left panel. Fuel pump relay is clicking when ignition turned on so assuming it's ok ? indicators working. As for the kill switch the clocks have been converted so tacho flashes when kill switch is on and that's ok. Anything else before I attempt the ignition barrel.

Edit
I've taken the ignition barrel out and cleaned it, seems ok, also put a multimeter on the plug that connects to fuel tank just above pump relay and am getting over 12v when turning ignition on for a few seconds. I've also tested the tip over which is within spec and tested the fuel pump relay as per the Haynes manual and appears to be ok. I've checked continuity in the wiring from pump to harness and seems ok.

I've had the earth wires rot & fall off the tank. There's enough connectivity for the fuel gauge to still work but the pump isn't happy if that happens.

Easy check when you lift the tank.

Where are they please
