Those plugs look like they have been in there a very long time, unless it's the photo perspective. #2 looks like the gap is closed.
I doubt that plugs alone would be the problem.
Test for spark, cranking and running. I know it wont run after cranking. You could disconnect the power signal lead from the starter and use a remote starter (push button with two leads) to start the car while another person holds the key in the crank position.
If it keeps running then start checking the ignition "on" circuit to see if it is not getting to the coils.
Start (crank) and run are two separate circuits.
In most systems the crank circuit runs direct battery voltage to the coils and after start the voltage is regulated to prevent an overcharging alternator from frying the coils.
