As was suggested a compression test would be in order.

The car may have poor compression from sitting and having the rings get a little sticky. The gasoline that is injected each time you try to start it washes the cylinder walls down further reducing the rings ability to seal and create compression.

Disconnect injector wires

Crank engine over to clear gasoline from cylinder; remove spark plug wires; crank it again.

Squirt two tablespoons of engine oil into spark plug holes; crank engine over to distribute oil. Squirt another tablespoon of oil in and crank over a couple of times.

Reinstall spark plugs (new plugs would be a nice addition).

Reconnect injector wires.

Try to start. If it starts let it run until it reaches normal operating temperature. Sometimes sticking rings will loosen up almost immediately while other times it takes much longer.

Good luck and let us know how it works out.
