My bike wont start over night

Security. Turn the key to run. Let it sit for ten minutes, off for thirty seconds. Then try to start. Do this three times for a relearn. Don't try to start.

During the night or after the car sets for a while. The battery voltage will drop from the normal 13.6 to 13.8 volts when running and Charging, to between 12.3 to 12.6 volts. If the Crank Sensor is going bad, it may not operate correctly with the lower voltage. Check your Battery Voltage in the morning with a Volt Meter. If the Battery Voltage is lower than about 12.3 to 12.5 volts. You may need a new battery. Try leaving the battery on a low current Battery Maintainer overnight and see if it starts in the morning. I have seen many cars that shut down with Low Battery Voltage. Darn these New Fangled Cars and their Computers! FYI, we have never seen a Crank Sensor fail in this manner..... Check the RESTING Battery Voltage.

no crank?
or
no start.?
or post, it cranks fast but wont start, that is 100% clear.
my car , i can push and gravity start it. (M/T stick)
if it wont crank did you try jumper cable start to a donor car?
did you check all fuses?

Sounds like a slightly grounded wire. If there are any electric features that work with ignition off I would start there. Remove key as well.

weak alternator not charging the battery fully or an elictrical item in your vehicle using the power , like a light or radio etc

well it is a connection problem or something is draining battery over night. Check all cables. maybe explain a little more detail only in morning? does it sit all day and no problem just over nite? Does it crank but not start?

There could be a few things causing this. When the car finally starts, is there any smoke coming out the exhaust pipe? White smoke would mean your headgasket is leaking and is letting coolant into the engine, then it is burned along with the fuel. Does the car run hot? Meaning has it ever overheated? Back to the smoke, if its black, your oil is getting in and is burning.

Now, the reason why it would be hard for a car to start, could be, a leaking headgasket, flooding the car while the car is sitting.

And yes, the car would be able to crank, but just wont start, for a while...because it has to get rid of all that fluid that has leaked into the engine while sitting at night.

Another thing you could look at, is your fuel pump, is it supplying a sufficient amount of pressure? If it isnt, it will take a while for it to pressurize and deliver fuel into the engine. You can check the fuel pump yourself by renting a fuel pump pressure tool from stores like autozone, kragen and more.

Your gas cap on tightly?

Good luck with your problem.

if you still havent started the bike yet from sitting.then i dont think the choke has anything to do with your problem.but ether way take the plugs out.I think your piston rings are frozen from sitting.did u winterrize it?with the plugs out pour a little auto trans fluid in each cylinder.very little.now crank the bike over to coat the cylinders. becareful it could be messy now let the bike sit overnight.the next day crank bike over again.but this time for a few tries.then install fresh plugs.and try to start it.p.s there will be white smoke from the transmission fluid. that will go away in a couple of minutes.then all should be good.

you have water in the fuel line

getting enough cranking amps? could be battery
