Check your batt connection wires first then if they are ok look at wireing harness or starter

It is ur security passlock. If it happen again watch the message board if it flashes security wait 10 minutes then try again

also check ur pcv valve, any vacum leaks may lead to it not starting, i have no idea why your playing with the headlights tho?
