My phone turned off yesterday n now won't turn back on at all. What do I do I need to use it today

What burning software/version are you using?

I've just got the same problem, don't know what to do!

the engine turning over is not a starter problem
flooding is , broken timing belt is , no fuel pressure is , no fuel in the tank is
have the fault codes read to determine the fault

same

The power indicator should blink 1-5 blinks when it wont power up. If you let me know how many blinks your getting I can assist with the problem.

they do go bad

replace the switch they do go bad

The voltmeter should only go as high as 14-15 volts when the engine is running. I would check for a poor connection between the battery and starter.

Here's a fix that worked for me today! I couldn't make it turn on for over 24 hours. As a last-ditch effort I put my hairdryer on hot and aimed it at the on/off button. I waited 20 seconds and it turned on! (took about 20 presses of the button). In my mind the heat from the hairdryer is expanding the circuit board so that the things that aren't connecting can connect. Hope this helps!

Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.
