There are many possible reasons for a no-start. EZK failure is pretty low on the list. Relays (fuel pump, LH and EZK) are at the top. Crank position sensor, fuel pump and fuel filter are next along with alarm malfunction. LH is in the low middle along with short in the injector harness.

Look here for some advice:

Wiggle The crank sensor wires on top of the bell housing behind the air cleaner and try and start it again.
The crank sensor is the triger for the ignition

Relay, Relay, Relay. The basic info here is missing. Fuel? Spark? Timing?

Ok that tells us that it is intermitant so it is more then likely an electrical connection.
Well it is not starting check for spark. It should have a nice blue spark, orange is a weak spark.

I'd say your battery is weak. Pull it and put it on a charger overnight.

Aftermarket alarms can cause problems, do you have one?

If that was from cold, then the car is quite likely to flood when you restart after running for such a short time. If you do that again, try starting with your foot to the floor until it clears and fires up.

If that doesn't work, replace the battery ground strap regardless of how clean the ends are.
