My keeway 2010 50 won't start up fully

Sounds as though the battery is no good,
unless you know otherwise & also had it tested
Charging a battery doesn't address it's internal
condition
You have battery cables that corrode inside & can be
voltage drop tested
You have the starter & solenoid,ignition sw & such, to name
a few,lots of possible causes & things to check

if it has hit a object, the flywleel key is partially sheared, and needs to be replaced. they are very inexpensive,CHEAP. this will through the engine out of time just enough it wont start.

Check the wall outlet has poser and make sure the plug is fully inserted.

how do you know it is fully charged? i think it may be dead battery

Apparently a gear from the kick start level has become jammed which is why the engine won't turn.

You might want to post this question in a different section. This is the computer games section.

Make sure battery terminals are clean & tight.Also make sure polarity is correct & battery is fully charged.Thats a good start

Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.
