Electrical problem
1976 Dodge Van V8 Two Wheel Drive Automatic 69000 miles

I have a Dodge 1ton van with a 360cid & 727 auto tranny, I can only get it to turn over in nuetral or if I arc the silinoid, but it will not fire. I have spark & fuel, I replaced the starter, starter silinoid, starter relay, plugs, wires, cap, rotor, The Nuetral saftey switch, battery & both cables. I still am getting no changes. I turn the key in park & it just does 1 click & then nothing, but in nuetral it turns over but does not fire. I need to know am I missing anything?

Do you
have the same problem?

The ignition switch uses a ground in the transmission to energize the starter solenoid. If it starts fine in neutral, but not in Park you have maybe a couple of problems. If neutral energizes the pull in solenoid, the ballast resistor may be no good. Jump across it to check it. The neutral switch may not be switched properly by the valve body detent, so it is internal. Eventually, it should be fixed for safety. The connector can be pinched for repairs to that.
Now you have changed plenty of the normal secondarty ignition components, so the primary(coil control) may have a problem. You need 12 volts at coil in start and in run. Their is a difference in both key positions but with the key on, there should be 12 volts at coil positive. If no coil voltage at positive, you may have a ballasr resistor, or fuse link or just a problem with the wiring. If you have 12 volts with key on at positive coil terminal, it may be a ECU, Spark Control Computer, Distributer Pulse from the wheel, or the related wiring. Some Federal 360's had each, California built were far in advance of the rest. I used to jump 12 volts from the battery to the coil positive to check em first. My 80 was not California and used a ballast resistor for the positive primary cicuit on the coil and a square ECU on the firewall for the negative side using the distributer to give it a pulse. Maybe the coil is bad, or the distributor is not turning. The ballast resistor is white and on the firewall. OK Joe
