Not Starting

[Chappers]

All fuses checked and are ok.
No check on dash, rear plug disconnected and check comes on dash.
I've had the pump out twice and connected it to battery and it seems to run OK.

Just put tank back on after checking pump again, runs ok, connected it, turned ignition on and the fuel pump primed, but won't prime again.

So when you get pump pressure it starts??

Didn't start it as didn't have fuel line connected, got sprayed in petrol 

OK so tank off again and pump run up in tank while tank upside down, back on bike and it primed and started and ran OK, turned off then on again and ran, although the pump sounded rough while it was priming. Left it turned off for 5 minutes and back to no priming on ignition.

You might have done lots of testing of the pump but in my experience that would still be prime suspect,I have had moisture contaminated pumps that were very sporadic, to narrow it down put a test lamp/volt meter on the pump input to confirm that when it doesn't prime there is no power present and then with a wiring diagram start looking at the possibilities ,intermittent problems can be painful

Mate, its a K7 with chipped key, have you tried your spare key?

Funnily enough I was thinking about that last night, will take the spare with me next time and try it.

Will do

I don't think the starter works either if the bike can't see the key?
Worth a try though as it's an easy one.

Hooli, remember old threads, cranks but no fuel or spark. Have seen where they say Suzuki immobiliser can be turned off in ECU. Havent found proper instructions yet. I really doubt this on 14 but you never know.

I can't remember TBH grog, never having had such a modern thing.

I suspect if it can be turned off then the same Woolwich Racing kit that can remap the ECU is able to do it.

Agree Woolwich. My little car, 25 yr old Corolla, has a steel key, no immobiliser. Great car. Upgraded models in same era came with factory immobilisers and chipped keys. Now all these yrs later, electronics fail, pretty much no way to repair, perfectly good cars that are scrapped because of fucked up so called anti theft precautions.

So quick update, it has a spark, ...

Still worth a try as it is low effort (unless finding the other key turns into a search adventure  )

No different with spare key. Bought a tester that connects to pos and neg on battery, took pump and fuel gauge sender out and connected them on bike, so when I put the probe on the pos terminal on the pump and turn ignition on im getting 12.8v for about 3 seconds but the pump isn't priming, so looks like the pump is toast ? Any suggestions for a replacement please.

Edit; I sprayed a load of cleaner through the pump and got it going, put it back together in tank, fitted tank and it primed 4 or 5 times then stopped priming. I've ordered a cheap one from ebay to see if that works. I take it there is a filter inside the the plastic pump housing, and am wondering if this could cause any issues for the pump if its dirty.

Pump from Quantum Fuel Systems, Model HFP-384-U
