1985 Dodge Ramcharger No Spark
Turn key On do you have power to the coil positive?
Should be on the firewall-not there try the fender well-its a square box that has a 5 pin connector.
one wire goes to the ignition switch,wire to the ballast resistor,wire to the coil, and 2 wires goes to the distributor.
HTH-Good Luck
Spark computer! I think that one is attached to the air cleaner assy its been a long time-along with a 2 magnetic pick-up in the distributor run and start.
Suggested Repair
With the key on, confirm power at the coil positive. If no separate ignition module is present, look for the spark control computer mounted on the air cleaner assembly and verify the dual magnetic pickups in the distributor used for run and start, along with related coil and ballast wiring.
Conversation Summary
The owner of a 1985 Dodge Ramcharger with a 318 has no spark after replacing the coil, cap, and rotor, and cannot find an ignition module in the distributor, firewall, or fender well. An expert first suggested checking coil power and looking for a five-pin module on the firewall or inner fender. The owner later concluded the truck uses a spark computer instead of a separate ECU, and the expert said that computer is typically attached to the air cleaner and works with two distributor magnetic pickups.
