I AM HAVING TROUBLE STARTING MY TRUCK. SOMETIMES IT WILL TURN OVER BUT NOT CRANK UP UNTIL AFTER 2 OR 3 TRIES. I'VE ONLY NOTICED A COUPLE OF TIMES WITHIN THE LAST 3 YEARS THAT IT HAS EVER STALLED AND WOULD NOT START AT ALL (NO TURN OVER/ONLY A CLICKING NOISE). THE IGNITION COIL HAS BEEN CHECKED AND FIRES, PLUGS HAVE BEEN CHANGED, BATTERY HAS BEEN REPLACED.... WHAT COULD THIS BE?

Next time it refuses to start-Check the fuel pressure with a fuel pressure tester if okay look for spark
