Pick-Up Coil Resistance
- Disconnect distributor connector from wiring harness. Inspect for dirt, corrosion, or damage. Measure resistance across Orange and Purple wires at distributor connector.
- If reading is between 400-1000 ohms, pick-up coil is okay. Inspect wiring harness between distributor and control module. If voltage reading is less than 400 ohms or more than 1000 ohms, replace pick-up coil assembly. After test, connect distributor and control module connectors.
