I have a 1992 dodge B250, suddenly stopped on the road, crank but does not start?

. Check all under-dash and under-hood fuses with a test light or multimeter. Here's how:

. Ensure battery is fully charged and connections are clean.
. Test for codes.
. Test Ignition Control Module (igniter) and coil. AutoZone and O'Reilly Auto Parts will do this for free.
. Test for spark.
. Test for fuel.

Thanks for reply, I have replaced ECM and also checked ignition coil which is fine but no sparks in plugs. I have checked all fuses, checked fuel pressure, checked timing chain, every things fine, but problem is the same. Engne crank but won't start.
Let me know what else need to be done
Thanks,

You likely need to test/replace the Ignition Control Module. If problem persists, you may have a bad crank position sensor.

Thanks for your help, Finally I have started the Van. The refurbished ignition coil was not good so Then I Install an OEM ignition Coil. But I have another problem which is Odometer. I replaced speed sensor but still odometer won't show speed. I already checked all fuses. I do not know what I am missing.

Thanks
