This problem occured on the highway. the engine just stopped. After I got it home I discovered there was no ignition. Further test revealed that there was no voltage at the coil. Tested with meter with engine turning over. No voltage. Where do I start. Is there an ignition relay ? If so where is it?
I have the same issue on a 94 B250 - replaced ECM, cam and crank sensors - still only coil primary with initial relay cycle, then nothing during crank. Was told ECM needs signal from cam and crank to send primary to coil. Very confusing - all wires connected.

Then i think i'd be dumping some soapy water on the intake gaskets checking for leaks. ANd wiggle the **** out of all vacuum hoses. ( you probably did that) And if there aren't any, your cam could be tired. You got a tough one there. Hard to figure with a keyboard.

The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module. This causes the engine to shut down.
Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump. Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.
