Starts but wont run after ignition switch is returned to the run position from the start position.

The problem is that when you have the switch in the START position, you are getting power to the ignition system, but not when in the RUN position. Most likely causes are a bad ignition switch, a faulty aftermarket alarm system [if it has one] or a bad ballest resistor wire going to the ignition coil's + terminal. You need to break out your test light and start checking to see where the fault lies.

99 Regal GS 3800 supercharged wont crank key in ignition all lights go off and car does nothing help!!!

Sounds like you may have possibly TWO problems here. The ignition key not turning past the run position or even to the run position is most likely a lock cylinder issue and may be fixed by replacing the ignition lock cylinder, As for the power being killed when turning the ignition to the start position, that sounds like a defective ignition switch. these items are two seperate parts. The reason for the turn signal issue may be related to the ignition switch fault.
Hope this helps.

Why won't my '66 Mustang start with the ignition switch in start position?

Change your ignition key module and that will fix the problem. Problems with key modules can be attributed to the weight of the owners key ring. Some people have massive key rings with all sorts of gadgets on them causing them to become very heavy. This puts an unexpected load on the key module and the load can double with it swinging from side to side ect... Best advise, keep the key ring simple and light.

81 Ford pickup starts while key is in start position, but dies when you release the key to run position.

You're probably loosing power to the coil or the ignition module from the key switch. The ignition system gets power from the key switch in the on position, and also from the starter solenoid in the start position.
You may need to trace the wire from the module to the key switch and check that circuit.

1987 dodge ramcharger stay running after key is in run position.

The ignition switch has two positions inside the switch. There is an ignition feed when the ignition is in the crank position and another feed for the run position.

Both feeds may come out the same external terminal on the switch, but internally there are 2 contact points, one for each positon on the keyswitch.

The common symptom is the engine will hit or run briefly off the startup and then die. It does this because it loses the ignition feed. Not really familiar with the module wiring for a Chrysler, but I was 37 Years old when your car was built. In the day, you could bypass the ignition switch and wire a power source(alligator clip) directly to the coil + terminal and once the car was started it continued to run this way.

Then some nut invented the solid-state Module. It complicates testing and you know the rest.

You can get wiring diagrams free at by registering your car. I remember tuning up the dual-point distributors and the 440 Six-Packs for this era car.

Please rate my info.

My 1991 pontiac firebird only starts and runs when you hold the key in the start position. As soon as key is released the car shuts off. I have replaced the ignition module and ignition switch, but the...

Sounds like something is getting power only in the start position.
If it shuts off like you are loosing fuel pressure, I would check the fuel pump relay for power and a ground signal from the computer. The computer grounds the relay for 3 seconds while cranking, then only if it sees oil pressure to know the engine is running. There may be a faulty relay that is affecting the ignition system too.

My 1991 eb ford fairmont starts when i turn the key but stops as soon as i let the key go

Hello, It sounds like a bad Ignition switch. The keyswitch provides power to its terminals in back of the switch. The engine will have power to turn the starter and run the engine when the engine is in the START position. When the key returns to the RUN position, the next terminal on the switch is suppose to provide power to run the engine.

When the electrical contacts inside the switch wear out, the power is not put through the plug-in terminals. That is when you replace the Ignition switch.

To replace the Ignition switch, if it is in the steering column, you disconnect the negative battery cable first, and then remove the plastic cover on the steering column. There are screws under the bottom cover and you just remove them through the small holes moulded in the plastic cover. There may be a hole near the bottom of the Ignition switch which requires a long nail or drillbit to press a release spring.

Usually the key needs to be in the ACC or RUN position and the key core will pull out of the switch. Then you make a mark on the frame of the steering column before removing the switch. Some mounts are adjustable and some just bolt up and making a mark is not necessary.

Then reverse the removal procedure to reinstall a new part.
