Help..

Crank no start 2017 6.8 E-350. Had battery disconnected over the winter months and now will not fire. Checked fuel pump relay,pcm relay and other fuses and relays. Check engine light comes on with key on tach moves when cranking. Had a spare coil and plug from a different e 350 and shows no spark.

This might be related to the crankshaft position sensor. If the van sat without being started its possible a rodent may have chewed into the wiring.

Ditto on this. Also, with the key on, check for +12V between the coils (one wire should be red with a tracer, that should be +12) and ground. If you don't have +12 there, it won't fire the coils. Same thing for the injectors.
