T ried to start but dash digital readout said starter disabled try again in three minutes. Cleaned the keys and tried several more times but same message kept coming up. Won't crank or start. Same readout. Do you have any recomendations as to what to try next?
Using an ohm meter, measure the resistance of the key resistor pellet and record. Next, find the 48 cavity connector just to the left of the steering column. Disconnect it and install an ohmmeter across the two wires at terminals E-12 and E-13 (two little white wires inside an orange wrap) going back to the steering column. Insert the key into the Ignition Lock Cylinder and check the resistance at this connector. It should read the same as the reading obtained from the key resistor pellet. Watch the ohmmeter while turning the key all the way to the crank position and back several times. If the reading is open or it varies, the Ignition Lock Cylinder is defective. Replace the Ignition Lock Cylinder and bring the old key to the dealer to have it matched to a new key. There are different resistor pellets available and these pellets must remain the same value.
