No Spark, No Fuel Pump, No Start 1994 B250 Ram, 3.9liter
What is your question?
Seem to have the same issue as a lot of other folks I have replaced so far the following parts and still have the same existing issue. New ( Ignition switch, ECM Module, Coil, Coil pickup, rotor, cap, fuel pump, crankshaft sensor, fuel pump relay, auto shut-down relay.) This issue is costly and becoming extremely mind boggling. Vehicle won't start unless the engine light comes on. cold starting you have to play with the ignition turning it on and off until you hear a loud clicking noise coming from the ASD Relay and fuel pump relay where current seems to be bouncing back n forth. After the loud clicking comes to an end, the engine light starts to illuminate and once it gets bright and stays on, the vehicle fuel pump can be heard coming on and then it will start. Is there another relay on this vehicle? maybe an ignition relay? Ignition Feed relay? What about the Ignition lock cylinder? could any of these be the culprit?
What makes this problem better or worse?
Playing with the ignition switch and wires near the carburator seems to have some effect

RepairPal Certified shops can diagnose and repair your 1994 Dodge B250. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Wiring problems are prevalent on these vehicles! .. Turn key on - start wiggling wire harnesses while listening for the relays and fuel pump to turn on - possibly corroded / poor connections under the fuse / relay box.
Nothing other than old fashion *hands-on* testing is going to reveal this problem.
Very difficult to to offer any other response that is helpful here online.
Good luck!
