1992 w150 318 auto 4x4 cranks no spark. fuel pump is good crank senser is new cam senser is new asd relay is good. getting a code for no crank signal .swaped the ecm out of a friends running truck. still no luck.any help is welcome

 

Have you checked the ignition module?

 

I assume you are referring to a code 11? Does the fuel pump come on briefly when you first turn the key on?

Remove the distributor cap. Rotate the engine until the rotor faces the rear of the vehicle. The movable pulse ring will be contained within the magnetic pick-up inside the distributor. Back probe the gray wire on the distributer harness with a paper clip. Touch the + lead of an analog volt meter (not digital) to the clip and ground the - lead. Key on (not running) you should have 5 volts.

If no voltage check for voltage on the orange wire. There should be 8 volts with key on (not running). If voltage is present on the orange wire you go back to the gray wire and crank the engine over. The meter should fluctuate between zero and 5 volts.

Let me know what you get.

 

fuel pump does cycle have ckecked the cam position senser and all voltages are correct .i am checking the crank sensor voltages tonight and the ground splice behind the distributor

 

If the cam positioning sensor is OK and is pulsing, have you checked the ignition coil?

 

coil is good. swaped from running truck

 

found the issue bad ground from the crank senser. will post pics of the found issue since this seems to be a comon problem.
