computer. It doesn't pickup asd. We changed the computer and got the same result. Have checked all wires for continunity, grounds and cross connection.

 

is the cpu new or used? if is a used cpu it could also be bad. you may also need to look at the relays.also look at the connecters ends and make sure that they are not bent or loose or missing.also make sure the wires are seated in the connector.i hope this helps

 

did you check the crank shaft sensor. My buddie's jeep did the same thing and that was the problem.
