2013 ktm 450XC-F No start

Have you checked the valves?
Timing chain?
Fuel pump and filter?
Fresh fuel?
Some of these had a crimped fuel line from the pump right from the factory. It will deliver some fuel, but not enough.
There is a post on Vital about this with photos.
Have you tried starter fluid to see if it will fire up for a few seconds? If so, you still have a fuel delivery issue.
Spark plug?
Do you have a good bright Blue spark at the plug?
TPS setting should be about .5-.6 volts at idle.

i have checked all of the above except the fuel pump and internal fuel filter... i know its a fuel delivery issue for sure because yes i can get it fire for a few seconds on some wd-40... but it wont stay running.. you dont happen to know the correct fuel pressure for these do you??? and thanks for the tps info i had it set in the correct voltage range... im leaning towards fuel pump for sure because the injector pulse when attached to the bike opposed to the cleaning tool seams substantially weaker... will update with fuel pump pressures shortly

I believe its in the neighborhood of 50 psi. Do you hear the pump priming when you hit the start button? Internal tank filter
could be gummed up after sitting that long, especially if it had ethanol.

It was the fuel pump did a test on it it only pushed 9 psi of pressure... bought a new one started instantly.
