Hi,

When you turn the key, does it crank? If it does, it is not likely that the battery or starter are a problem.
Best thing to do is scan for codes, as this might tell alot.
For instance, you might have a bad crankshaft sensor. This will cause crank-but-no-start situation.

Hope that will help.

You say it will not start the first turn. Does it start after that and just crank for a few extra seconds? If so then you have a bad check valve in the fuel pump assembly.

Do a fuel pressure check at first start up and see what the pressure is.
