Cranks but won't start security light is on . Did the 10 minuet didn't work someone said I need to change the switch

You tried it in neutral but did you take it out of park and force it back into park? Just a suggestion since sometimes the switch that tells it that it is in park needs a bit of a nudge sometimes.

I doubt it has anything to do with the key switch.
If the security system is the cause, the security warning light should be on.
Someone would need to check the circuit between the key switch and the starter when it fails to crank to find the problem.

Crank Sensor Bad.

it could be the starter or fuel pump what does the car do when you try to start it after you turn it off the first time

have someone check the fuel pump relay ,what type of car is it

If the security light is on then the car thinks someone is trying to steal it. If you can’t make the remote work then you might be able to clear it by disconnecting the Negative battery cable for about 10 minuets

you can not bypass the security in that car, it is built into the main computer, they have problems with the ignition switch screwing up and the only way to start it while the light flashes is to turn the key to ON but don't crank engine, leave on for 10 to 15 minutes until light goes out then start car.

turn the key on and wait till the security light stops flashing ( this could take as long as 30 minuets ) then turn the key off then back on but do not try to start the engine and wait till the security light stops flashing ( again this could take as long as 30 minuets ) then turn key off then turn key on and start engine.

most common on this vehicle after an engine wash is water in the spark plug wells or the igniters

Hey have you recently changed your head unit. I have a 2000 s10 2.2 and i recently hardwired my pioneer 4000ub head unit and the security light came on upon not starting. every time you try to start the car while the security light is on it will add 10 minutes onto your time. For the security light not to come on you need to check your wiring. just remember dont keep trying becuase it wont work!!! find the problem and fix it.
