Question type: Maintenance & Repair

I have 1998 dodge 1500. Went to go drive
the truck and only wanted to crank. Truck
ran perfectly fine then just wants to crank.
Has no fuel going to fuel rails, and has no
spark. Just sits and cranks. Replaced crank
sensor and nothing.

Check applicable trouble codes. Check for cam and crank sensor signals. As far as spark, check for primary voltage to coil, also fuel injectors. Dark green and orange wire, engine cranking. That voltage comes from asd relay. Some of these vehicles, the computer needs to see both the cam and crank sensor signals or it won't ground the asd relay.
