2014 KTM 250 sxf no spark no fuel pump power

Is power coming from the stator?

on my 15 husky fc 450 the seat rubbed a wire comming out of the voltage regulator and same thing turned over but no start

Also do a load test on battery. OEM batteries don't last very long and will show good voltage until put under a load of any type. If it's bad replace it with one of the new light weight Lithium Ion batteries as they will last.
There should also be a fuse under the seat.

Is there a fuse that popped?

ok, as I understand it...The fuel pump has to run before it will fire. Check the wires connected to the fuel pump in the tank. I have seen them come unplugged at the pump on ktm"S.

Do these bikes have a crank sensor? I know on most cars when the crank sensor goes they will usually show no spark or fuel because of it not functioning properly.

We had a starting problem on a couple of KTMs. One was the white wire shown above that rubbed on the frame until it broke. Couldn't see it until we twisted the connector around. The other was a broken wire inside the tank, no fuel. 22 gauge wire if I remember. Another time a bike wouldn't start and we didn't have the subframe bolted up all the way, loss of ground.

Disconnect the tip over sensor and reconnect it, this resets it.

Its a bad voltage regulator. The main power relay is power from that and if that relay isn't clicking on the ecu is not getting powered up. Another way to tell is if the fi light isn't lighting up when you first hit the starter button.

The main power relay is grounded through the voltage regulator. I had a bike in the shop that i work at that was doing the same thing. When i hooked it up to the ktm xc1 diagnostic tool it would ground the system out and it would power up the relay and run fine till i turned it off. If the roll over sensor was bad the fi light should be flashing a code it has nothing to do with powering the ecu it just cuts out spark.

It is a internal problem i think due to the regulator over heating. If you know of someone who has a ktm sx or xc 4 stroke from 13 up its all the same regulator try it on your bike and see if it solves the problem.

Hi did this issue ever get sorted as i have exactly the same problem cant sort it cheers

Same. i have chased this ghost for 6 months. Works sometimes and then dies in the middle of the trails. The FI light won't come on and no power to the fuel pump

Did this ever get sorted out my 2012 350 sxf just died and the relay clicks but not getting any power to fuel and the fi light not coming on.

On mine it was just the fuel line getting partially disconnected. It unsnapped partially in a tip over. After all I did to diagnose as the op and when I checked the fuel line at the filter it looked good but it was not. Nothing to freak out about. I wasted a lot of time for a simple fix.

My bike wont even turn over just hear clicking checked grounds wires new voltage regulator new battery still nothing fuse looked

Had a customer couple years ago with same problem. Turned out one of the wires behind front number plate broke at the plastic connector. wiggled the wire to locate. Wire was broke at the spade that goes in the connector. Re soldered the wire to spade and snapped it back in plastic housing and good to go.

I actually just had this happen this weekend as well. I had a minor tip over. I then started the bike it ran fine for about 1/2 hour when all of a sudden the bike died. I called my KTM dealer and brought it in. They were baffled what it could be. I guess the tech plugged in a diagnostic tool and it showed fuel pump issue. He then check my quick disconnect fuel line and noticed it was not fully seated. He disconnected it and then reconnected it. Then fired the bike up ran great after that.

I'm have the same exact problem with my 2018 KTM 500 exc-f with only 15hrs. I have the bike complete apart and been through the wiring harness countless amounts of times. Bike fired up then stalled now no spark or no fuel pump coming on but will crank starter. The harness is supplying the fuel pump with power until i plug the harness into the fuel pump connect then goes to zero voltage. List of everything ive checked.
Kill switch Okay
Ignition switch Okay
Inspected all grounds clean and dielectric all connections Okay
Swapped relays under seat No change
On relay for fuel pump white black wire has battery voltage when ignition off and goes ground when ignition on. I jump 12v to this wire and pump turns on and get spark back but wire im jumping with heats up hot like a dead short.
Please help.

i have a 17 ktm 450sxf.. doing laps.. pull over, won't start.. could bump start no problem.. pulled the seat.. and jiggled all the wires.. Started up no prob.. all i could hear was a click before. like the coil in the relay energizing .. werid. cause the voltmeter said 13 volts. once i wiggled, it was perfect.. might have been a battery terminal issue.. but i doubt it.. they were not wiggled. and were on tights.. whats the deal...

earlier i swapped out the shity tiny 4s2P samsung lithium pack and put in a new lithium https://youtu.be/zHhoKFpIVBI

Hello all brand new here seeking some help.

Details
Okay, so I have a 2018 KTM 500 EXC-F with 15.5hrs with no fuel prime or spark. I went out to go for a ride the other day and it fired up as normal quick and fast. I let the bike warm up before I left for a ride and I would say less than 10 minutes into the ride the bike stalled once coming to a stop. I cranked it over and it fired right up again so I took off and a minute later DEAD. I walked the bike back home and noticed I didn't hear the fuel pump wasn't priming. I don't have a wiring diagram to chase wire but do have one on order from ebay.

Things I've checked so far.
1. Checked fuse and all where okay.
2. Swap relays under battery for fuel pump.
3. Checked all wiring connections behind headlight back toward battery. Okay
4. Cleaned up all the grounds that I seen and put dielectric grease.
5. Checked for voltage at harness to fuel pump and got 12v
6. When I plug harness into pump I loose voltage...
7. I ran 12v straight to fuel pump and it turns on.
8. Checked fuel line disconnect at bottom of tank. Okay
9. I noticed when I turn the ignition off the fuel pump relay clicks 3 times
10. Inspected harness up and down form broken wires.
11. Inspected roll over sensor.
12. Checked kill switch with voltage meter continuity working Okay.
13. On fuel pump relay theres 2x white/red 1 yellow/red 1 white/black. White/black has 12v with ignition off and goes to ground with ignition on.

I'm at a total loss with the bike and don't no where to go from here. My buddy is coming over later to try and swap some parts.

Any help will be greatly appreciated.

FYI to anyone having this problem it turns out my ECU is garbage. I just dropped bike off from dealer which I bought it brand new. They are contacting KTM and it should all be covered by warranty considering it only has 15.5 hrs. The dealer I dropped bike off said they just had another KTM come in for same exact problem and could possibly be a bad batch of ECU...

I’ve got the same thing on my 2013 250sxf, bought it Saturday and since getting it home it’s created this fault!
