THEN CUTS OFF AND THEN JUST CRANKS NO SPARK, AFTER 20 SECONDS CAR WILL START AGAIN. THE ABOVE PROBLEM WILL KEEP REPEATING SAME CYCLE UNLESS AFTER YOU START CAR AND HAVE IT IN GEAR IT WILL RUN FOR ABOUT 2 MINUTES AND THEN DIE OUT. WHEN YOU TRY TO START IT AFTER IT CUTS OFF IT JUST CRANKS /NO SPARK. IF YOU WAIT ABOUT 20 SECONDS IT WILL START BACK UP. NO CHECK ENGINE LIGHT ON. CAM AND CRANK SENSOR BOTH HAVE BIN CHANGED. PLEASE HELP.

Code 18 means circuit to cam/crank sensor fault not the sensor itself. Maybe connector, wirirng, fuel pump circuit, damaged sensor on harmanic balancer. Inspect sensor ring on balancer see if teeth bent/damaged and look closely at connector see if a pin is bent connector fit loose
