Did first session, cutout momentarily once but fired back into life. Second session - cut out in the middle of Druids. Wouldn't restart. Van of shame back to pits. Back at pits, restarted once. Now won't start at all. Dash lights come on and starter turns fine. Fuel pump does not prime. Checked all fuses - ok Solenoid - appears ok Lifted tank to check pump wires and connector ok Battery box out. Wiggled, disconnected everything ok Immobiliser aerial ok All connectors pulled apart and reconnected OK. Basically it's not priming. Any ideas??
A kind man with a 749 had a stash of new relays... Put it in and..... Fuck all. Same! Error code 37.2 which is immobiliser. Fiddled with aeriel again. Nothing. Bugger.
Ricky.. I think it's time for a proper track bike, nice screaming 2 stroke 250Gp, no Immobiliser, just noise and smoke
Back home. Tried the procedure that @Sev suggested but that doesn’t work as my EODB light isn’t illuminated. Tried the red key - nowt. Basically, when I turn it on the red triangle light flashes twice and then the “code” symbol flashes on the dash constantly. No fuel pump priming. Error code is now 37.3. Battery is back on the optimate to charge, despite being brand new and had enough charge for me to keep trying to fire it up all day while trying to get it working.
I hate the looms and some of the connectors that started at 749/Ugly time.. I almost think there is a market for a higher quality loom run for several bikes, i’d remove the front to rear loom connector for starters.
Had another go at this today. Fully charged battery New relay Swapped the entire front (race) loom for a brand new, never used one Took battery box off Took ecu out and cleaned all connectors, emeried the earth lead, nut,bolt and reconnected. Swapped the ignition aerial with my other one (known to be ok) Checked all wires around battery box and relay for signs of chaffing or damage - nothing found Rechecked all fuses, all ok Disconnected fuel pump and checked plug etc all ok Switched on and still no fuel pump prime. I can hear the relay clicking each time it is powered on. Error code 37.3 still. No amber light on dash, just a constant alternating of the “code” and temperature readout. I wiggled all wires while the power was on, behind battery, around ecu, at pump, into clocks, every-fuckin-where...dead as a dead thing. Arse.
i have had a hairline crack in ecu fuse cause loads of inexplicable grief and 37.2 errors also maybe check your side stand switch (or the quality of the bypass)
Hi, my 999 left me stranded once. Engine just went out. Pump didn't prime...Waited a while...Tried again, pump primed, bike died after a minute running...pump didn't prime...and so on. The fault was a broken cable in the aluminium housing that goes into the pump. Its not visible as it filled with epoxy, but the pump didn't get power because of that broken cable. You can either repair it, but you have to use fuel resistent epoxy ... or buy a repair kit. Good luck! Andreas
Thanks guys. My next course of action was going to be to swap tanks between the road and track bikes. The strange thing is, when I was at Brands and it conked out on track, when I got back to the pits it did start and run again. Subsequently it wouldn’t restart. Sounds like a dicky wire/connection.
