Need a little help here please.

A test you can make which might give some idea of the distributor (actually 2 tests)

1...Put your meter on low AC (that's right AC) volts and connect the meter to the two distributor pickup wires. Crank the engine or spin the dist. and it should generate about 1v AC

2...Unhook the dist. connector and turn the key to "run." Take up the ECU end of the dist. connector and tap the bare terminal to ground. Each time you do that should make 1 "snap" hot spark
