Daewoo cars have track record for dependability in addition to solid construction. The most important part of a car's design is the safety features. Circumvent excessive risk while motoring by insuring that your car has the safety gear that you want. A vehicle's Neutral Safety Switch is located on your clutch in the case that it's a manual transmission, and on the shifter in an automatic. A broken Neutral Safety Switch can cause your vehicle to suddenly start in gear, causing vehicle damage or personal injury.
If you don't have the Neutral Safety Switch, your vehicle will fail to work. The Neutral Safety Switch is typically situated below the clutch of trucks which have a stick-shift transmission. The primary function of a Neutral Safety Switch is to stop your truck from starting when in gear. The car's Neutral Safety Switch acts as a safety feature, keeping you from starting the engine if the car is in gear. The Neutral Safety Switch is an electronic part which is essential while starting your car.Here's a link to what it look's like.
Most neutral safety switches are combinations of a neutral safety switch and a backup lamp switch. Others have separate units for these two distinct functions. When the reverse light switch is not part of the neutral safety switch, it seldom needs adjustment, as it is directly activated by the transmission or the gear selector linkage.

A neutral safety switch allows current to pass from the starter switch to the starter when the lever is placed in the P or N position. Some neutral safety switches are nonadjustable. If these prevent starting in the P or N position and the gear selector linkage is correctly adjusted, they should be replaced.
To adjust a typical neutral safety switch:
Place the shift lever in neutral.
Loosen the attaching bolts for the switch.
Using the angling pin, move the switch until the pin falls into the hole in its rotor.
Tighten the attaching bolts.
Recheck the switch for continuity. If no voltage is present, replace the switch.
The switch sometimes controls the operation of the back-up lights also. With the engine off and the key on, put the selector in reverse position. Check the back-up lights to see that they are on. Then, check in the drive position to see that they are out.
Its possible that your have some "no start" condition or intermittent problem about this; to test it, shift the Trans into Neutral, if the engine starts in Neutral, the problem is the Neutral Safety Switch. If the engine still will not start then the problem will be in the Ignition Switch.
The heat of the engine is usually what does in the starter motor. The Neutral Safety Switch is not common at all. It is fairly easy to remove, it is bolted to the drivers side of the transmission where the shift cable attaches. The problem you run into when replacing the Neutral Safety Switch is that the connectors are glued into the switch and will not come out. This will require replacement of the connectors if you replace the switch.

The neutral safety switch is located on the top and toward the base of the steering column almost to the floorboard.
To remove or install the neutral safety switch be sure to place the shifter in the neutral position, then dis-connect the wire connector at the neutral safety switch, then remove the securing screws and then remove the neutral safety switch.
Install the new neutral safety switch and do not over-tighten the securing screws, then remove the alignment pin and re-connect the wire connector to the neutral safety switch. (be sure not to remove the alignment pin until the neutral safety switch has been installed)
Check to be certain that the vehicle only starts in "Park" or "Neutral". Here is an image to help assist you, and let me know if you require any further assistance.
The neutral safety switch is located on the side of the transmission and it is usually attached behind the shifter linkage and it is secured with two small bolts that can be loosened up to allow for adjustment of the neutral safety switch.
To adjust the neutral safety switch place the transmission into neutral, (block the tires) there is a notch or and indent marker on the housing of the neutral safety switch that should be lined up with a line on the face of the collar that is around the shifter detent shaft, and if they are not in alignment then loosen the two bolts that secure the neutral safety switch and then turn the neutral safety switch until they are aligned and then tighten the securing bolts to the neutral safety switch, and then test the starter. If the starter fails to engage then either the neutral safety switch is faulty, the neutral safety switch has been by-passed all this time and the by-pass (I will usually find things like a paper clip shoved into the vehicles wire connector with electrical tape around it) has fallen out of the wire connector from the vehicle wiring harness, or the battery just went dead. if you have the neutral safety switch from the old transmission still available try using it to test the neutral safety circuit. I have provided you with an image to help assist you adjust the neutral safety switch.
The back-up light switch is incorporated into the neutral/park safety
switch. The neutral safety switch on 1988-94 models is mounted in the
Neutral Start/Back-Up Switch The procedure is for switches that are mounted on the
transmission only. This adjustment is performed with the switch
removed from the vehicle. Neutral position tool J 41364-A or its
equivalent is required for this procedure.
Position tool J 41364-A or its equivalent onto the park/neutral
switch. make sure that the slots on the switch are lined up with the
lower tabs on the tool.
Rotate the tool until the upper locator pin on the tool is lined
with the slot on the top of the switch.
He's right I would check Neutral safety switch first. Make sure B+ only comes out of one end of it when pedal is released. Only time B+ must be out of both sides of this is when pedal is depressed. Ignition switch can't go to starter directly B+ starts at ign switch to neutral safety to solenoid on starter.
Most neutral safety switches can be adjusted.
