Hi Susan , when you turn the key to the start position does the starter engage an spin the engine ? If yes , pull a spark plug wire an check for spark , do you know how to do that ? You can buy a spark tester at the auto parts store or stick a screw in the spark plug boot a hold it near ground .( metal on the engine ) Have someone crank the engine . Does it have spark ? If not could be the coil or crankshaft position sensor . Watch this video !
Primary voltage to several systems, including the ignition coil, dark green wire with orange tracer. That voltage comes from asd relay. There is a fuse for asd relay. To check for voltage the engine has to cranking. The control side of asd relay, the computer has to ground it before it will energize. Did you check wiring circuits for cam and crank sensor connectors before replacing sensors? Are there any applicable trouble codes?
Are you ok with testing wiring circuits?
Hi, First replace your plugs. Second check ignition coil(s) one maybe bad. replace with new. If all else is good, have your mechanic check the computer codes. (code scanner) Many of todays cars and trucks have computers to run and control the engine. (management system). Good luck
Not CAM or Crank angle sensor.. Try check supply fuel line pressure n spark plug n ignition coil output.. the ignition coil output should be blue spark n spark jump at least half inch.. But be careful coz its hi tension..
assuming you the coil, plugs, cap, rotor and wires are good. check the cam sensor, If you have 12 volts to the coil using a 12v light tester. The cam sensor responsible for sending info to the computer telling it that the cam is turning, then the computer tell the coil to dispurse the charge/sparks to the distributor as distributordistribute the sparks to each plugs from the rotor of the distributor. Replace the cam sensor, it tend to go bad over period of time.
YOU NEED TO CHECK DARK GREEN/ORANGE WIRE AT IGNITION COIL WHEN CRANKING ENGINE FOR POWER..IF NO POWER,SHUTDOWN RELAY IS NOT BEING ENERGIZED..THIS ENGINE ALSO HAS CAMSHAFT POSITION SENSOR ON END OF CYLINDER HEAD..ENGINE CONTROLLER NEEDS CAM AND CRANK SIGNALS TO ENERGIZE THE SHUTDOWN RELAY..UNPLUG CRANK SENSOR AND CHECK VOLTAGE ON ORANGE WIRE..SHOULD HAVE APPROX 8V..IF NOT..UNPLUG CAM SENSOR AND SEE IF 8V SUPPLY RETURNS..IF NO POWER TRY UNPLUGGING VEHICLE SPEED SENSOR LOCATED IN TRANS HOUSING WHERE RIGHT SIDE AXLE COMES OUT OF TRANS..IF 8V RETURNS..THE SPEED SENSOR IS SHORTED INTERNALLY..THESE 3 SENSORS SHARE THE SAME 8V SUPPLY CIRCUIT..WITH SPEED SENSOR UNPLUGGED,PLUG CRANK SENSOR BACK IN AND TRY TO START ENGINE..HAVE SEEN THIS SAME PROBLEM AT WORK RECENTLY
