Van died on highway cranks but won't start. There is no spark. Replaced coil and cranking sensor with no luck. Took van to pep boys (i know) and they can't find problem. Any help out there?

Have you checked for any trouble codes?

Is the ASD relay working?

No way of checking codes and have not checked ASD relay or know it's location

Without starting the engine, turn your key on, off, on, off, on and leave it on. Watch your digital odometer and it should list the stored trouble codes. Post those trouble codes here and perhaps we can point you in the right direction.

The van is for work and was desperately needed. Unfortunatley had to bring to dealer. It was the ECM. Thanks for all the help. It was appreciated.

Well at least it's fixed. :)
