Hi,

This sounds like a fuel pump or the crankshaft angle sensor has gone out. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

Please run down this guide and report back.

It located on the left of the crankshaft pulley at the front of the engine. Here are the directions for replacement. The attached pic correlates with the directions.
