Sounds like an electical problem.
If the car has been sitting for a year, the battery is dead, or at the very least, near dead.
Have you had any little visitors inside playing with the wiring?
Check all your fuses, Your grounds, Look for bad exposed wires, Battery connection and charge.

Hi Matt
I would definitely take off the main Earth wire from Negative Battery Post to Chassis and the Engine and really clean the cable end and the connecting point on the Chassis and engine.
Might recheck the positive Battery connection is squeaky clean as well, then try again.
It would be helpful if you could monitor the battery voltage from chassis to Battery positive terminal with the engine running.You should see about 14.5 volts here if all is OK.
