Neutral Safety/Back-up Light Switch
This is a combination switch which controls both Neutral Safety and Back-up lamp circuits.
C6 neutral start switch
Removing the AOD neutral start switch
Removing the Manual Lever Position (MLP) sensor
As of 1994, the neutral safety switch is referred to as a Manual Lever Position Sensor (MLP).
Adjusting the MLP sensor
Park is the last detent when the manual control lever is full forward. Return 2 detents toward the output shaft for Neutral.
I hope help you. Good luck (rated this help).

HI. Yes, this is possible, but there are other reasons for this issue, as well. Use this step by step troubleshooting procedure to help isolate the issue. Step 4 deals with the neutral switch issues.
Check for 12 volts on the large wire attached to the top terminal on the starter relay. It should have battery voltage. If not, the battery, terminals or wire is bad.
Check the small wire on the solenoid for power when the key is in the start position. Remove the small wire on the solenoid and have a helper hold the key in the start position. Check the wire for battery voltage. If there is voltage, the starter is bad. If there is no voltage, replace the wire.
Check the fuse in the fuse box under the hood on the left fender well. If it is good, check the relay by pulling it out and checking for power at one terminal with the key off. If there is no power, the problem is in the fuse box between the fuse and the relay. If there is power, have the helper hold the key in the start position once again and check for power at another terminal from the ignition key. If there is power, the relay is bad. If there is no power, the starter circuit is suspect.
Check to see if there is power to the neutral safety switch if there is no power at the relay. Use the voltmeter to check for power with the key in start. If there is power going in, check for power going out. If there is no power going in, the security system or ignition switch is suspect. If there is power going in and none coming out, the switch is bad. If there is power coming out, the problem is between the neutral switch and the relay.
Remove the cover on the bottom of the steering column. Check the solid yellow wire for power when the key is in the start position. If there is no power, the ignition switch is bad.

Under dash driver side look behind the upper arm of clutch pedal and you should see a green and black wire coming from the button (switch) assembly on the firewall. The wires go up above the clutch pedal. About in the middle of under dash on the left side you should see a white connector these wires run to. Disconnect. I just had the problem and not only starts now but not stalling like it was but it's only been one day but tested it pretty good.
