Does your ignition key have a chip in it?
Customer: replied 1 year ago.
Yes....I tried 2 different keys cleaned contacts on keys and inside cylinder....car has 77000 original garage kept..no corrosion
Expert:  Dave Nova replied 1 year ago.
This problem is often due to a break in the wires coming off the ignition lock cylinder. Go under the dash and find the wiring coming out of the steering column. You should see a pair of thin White wires encased in Orange insulation. Use the ohmmeter to test resistance across the white wires with the key in the ignition . If the resistance does not match, the wires in the column are broken. You can then either replace the lock cylinder or you can bypass the wiring by placing a resistor across the two white wires. Resistor must match the resistance of the chip in the key.

Hi Dave
I unplugged the connector and it has ohms when I put the key in but when I turn the key it drops to 0
Expert:  Dave Nova replied 1 year ago.
This shows that there is a break in the wire. Either replace the ignition lock cylinder or permanently install a resistor to bypass this feature.
