Husqvarna Te 310 R Starting Issues

Hi!

Finally, my Husqvarna TE 310 R is running again. The fuel pump was broken and I had to test several ones as the original one costs almost 500€ (I am from Germany). Now there is another problem: I'm having starting issues, without the cold start lever, the bike won't start, at low speed the cold start lever is needed as well. The only thing I did before the fuel pump was replaced was getting a new temperature sensor, as I heard these often cause issues. As the temperature sensor was the only thing that was replaced other than the fuel pump, I suspect is has to do with this one. Is there anything that can go wrong replacing the temperature sensor (maybe there a possibility to calibrate it)? If you have other suggestions, please let me know.

Thanks in advance!

You might need to have your ecu re-tuned or reset. Also how long has your fuel been sitting in the tank. Bad fuel can cause the fuel filter or the fuel injector to clog.

check your fuel pressure.

How do I reset the ecu?
The fuel is about half a year old, gonna check that too.
