There is a cable from the gear shift lever inthe cabin to the shift lever on the right side of the transmission. The shift lever engages a slotted lever which is part of the inhibitor switch. As the cable moves the shift lever through the various positions, the lever on the inhibitor switch moves, making and breaking its internal connections.
Check to see if you can start the car with the gear selector in neutral. The inhibitor switch is adjusted so that it’s contacts are closed when the lever is in neutral, and to open when the lever is moved up or down from there by about 1.5 degrees. If the contacts remain closed more in one direction, and open earlier in the other, then the inhibitor switch position has to be adjusted. When the position is correct, the switch should be closed when in Park.
If not, then it’s possible that the shift cable is binding. Also, the inhibitor switch and range select lever that activates it are exposed to the elements. This should not normally be a problem, but it’s also possible that there is dirt or corrosion that is preventing the shift lever from moving fully when the gear shift lever in the cabin is set to Park.
The inhibitor switch is checked by disconnecting it and measuring the continuity between the contacts while varying the position of the gear shift lever in the cabin.
