Like it says, My 99 4.0 auto trans ranger has 165000 on the clock. This morning went out and it will not start, been a daily driver and had no problems. Engine spins over good, but no spark an checking for fault codes brings nothing up. Any ideas...........

 

check your coil

 

Is there anywhere on the fourm that goes over checking the coil, I did a search but couldnt find anythinh.............Thanks

 

Do a spark test. review results
Pull the plug on the coil and see if its getting 12v while starting review results
test for a switching signal on the back of the connector back probe it (ICM switching ON/OFF)

 

its full of gas, I just checked the fuel pressure, its at 60 psi.

 

do what i mentioned above

 

I gonna have to get some info on how to check the coil, I would think if its good I should also check the crank pos sensor.

 

i would bet its the coil.

 

Just checked the coil pulsing and found its not, checked the crank position sensor and found it was rubbing the gear, adjusted it and the engine fired right up !! thanks

 

CHECK TO SEE IF YOUR TACH IS WORKING WHEN CRANKING,CHECK TO SEE IF YOU HAVE INJECTOR PULSE, IF YOU DON'T HAVE THESE THROW A CRANK SENSOR AT IT..
