when it did this the engine would not physically crank over ?

was the starter making any clicking noises at all when you tried to start it ?

It will turn over then shut itself off, or it will click. The security light is always either blinking or staying on completely. But like I said its a roll of the dice. Starts fine and works a few times then randomly wont start.

when it will not start if you put your fingers on the crank/starter relay in the under hood fuse box do you feel that relay click with your fingers when holding the key to crank when it will not crank over ?
