IF crank sensor is unpluged will engine start

Check some fuses or see if you are getting any kind of spark. Spark at the plugs or injectors.

I'm having excatly same problem, found this sequence to ge the car running again..turn off ign, unplug cam position sensor, crank for 2 seconds, connect cam shaft sensor, crank again and it starts like that...

how much fuel pressure you have when turn key on

ALl Spark PLUGE MUST be REMOVED and With them OUT CRANK Engine to Blow OUT ALL WATER or it WILL HYDRO-LOCK and DEMOLISH the ENGINE

You might have a problem with your crank sensor or ignition. Remove spark plug wire and check for spark while turning engine over. When this happens unplug crank sensor near crank pulley then plug back in to see if it starts if so replace crank sensor.

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

Disconnect the crankshaft position sensor and turn the key on. See if the "no bus" message goes away and the gauges come back to life. If so, replace the crankshaft position sensor. On a 4.7 it is just above the starter, on a 4.0 it is on the left side of center of the bell housing. The modules all communicate on the bus and if it is down the vehicle won't start. I've seen the crank sensor short out and pull the bus down resulting in the exact condition you described.

No spark, ck the crank position sensor. bolted on engine at the front crank pully. Good luck. unplug and plug it back in to clean the wire connection/

Not sure what yor experiencing . Do you have crank no start or no crank no start? No crank no start is battery and cables issue. Crank no start is ignition , plugs, and fuel.

Check the fuel filter to make sure it is not pluged up, also check fuel presure, if its ok you possibly have a pluged cat. converter.
