Unlikely, given a battery at 9-10v will give the above issue, (and of course in all of the internets' history, no one has ever overlooked the obvious during online diagnostics)

But feel free to carry on with your humourless efforts- At least your second post added some value. Unlike Mine !

You can do a test first and pull out Fuse 2 (Fuel Pump Fuse) before shorting out pins 5 and 6 and you will see the FI Light flash the Fuel Pump error."
I got the bike running yesterday after checking wires and voltages across the wiering around the battery. I found out that the plug for the injector was faulty as it didn't give off any voltageafter jerking the wiers going into the connector the pump came alive again after taking it for a spinn it started to fuel cut and sputter again after about an hour instantly I checked the connector again but it was fine, and the pump was still active after this I decided I'm just going to deliver it to a local Ktm dealer and have them diagnose the bike even tho I'm sure it's just the injector or the pump running warm and swelling but thanks for the help anyway

It's all good the battery gives off 13 volts so the battery is ok voltage wise, the terminal is a different story I had to use a flat head to shape the terminal so it would fit the terminal nut seems like the previous owner fought it with a hammer but I got a spare battery that I'm puttting inn over the weekend
The bike is being delivered to the local Ktm dealer next Monday so now I'm just crossing my fingers it's just the pump or injector
But thanks for the help anyway

could be the plug or earths, but don't discount the wiring harness - harnesses are tight, wires and wire connections become compromised over time.

i.e. the Yellow and red feed is a common failure, it joins in two different places, and as they work loose the problem becomes intermittent -where it works loose over time it starts to act like a resistor until it breaks properly and stops completely

Yeah when it comes to wiring im not going to remove or do anything, i leave that to the people at KTM but all symptoms point towards the pump/fuel system to be the problem, but who knows Im just crossing my fingers that it wont be anything severe but thanks for the suggestion
