1978 Chrysler Lebaron - Answered Questions & Fixed issues

I don't understand how a headlight motor can keep a car from starting unless a short circuit has blown the fusible link to the ignition switch. Usually the headlight fuse would go first unless somebody tried bypassing the blown fuse with a wire (always a terrible idea). Headlight motors are probably on the front of the radiator mounting panel, right next to each headlight.

Check if you have power to the pump when the engine is cranking over. You will need a helper to do this. If there is no power with engine cranking, the pump circuit is failing-maybe bad pump relay or no signal to relay from the engine computer. But if there is power to pump with engine cranking, but pump is not coming on, you need to replace the pump.

MAP sensor will not shut engine off - suspect "Crankshaft Position Sensor which controls spark and fuel distribution.

Maybe one of the door switches, are worn or broken, worn ones can sometimes be adjusted to make the stick out. Push the door switches in one at a time with just that door open, (it should be on the door jam), if it stops, you've found the problem switch. Since the driver's door get much more use than any of the others, I'd start there.

Do you hear the motor run at all or do you hear nothing.

Under the car on the drivers side.

Hello Cher Hall, My personal relation with Chrysler... go back nigh 70 years to REVERSED-DORS, Living room rear seating and air-stream architecture... to SCAT-PACK HP (smokin') Power. My favorite being "can you say HEMI...??" So when some fair LADY sighs... "My IGNITION"... Years of FIRST RESPONDER and advanced electronics training MELD into a brilliant MOMENT (calculus) of wisdom... to say... IF YOU CAN'T EVEN MANAGE THE YEAR, MAKE nor MODEL... --- (you don't care enough). Your best bet is a LOCKSMITH . EASY answers are never easy... and there's no such thing as a free lunch. I don't suppose this helps... but in case you want t get thoughtful... I'll still be here... Same FREE price... Ready to answer your question.

PUT IN A NEW IGNITION SWITCH. THE KEY BUZZER IS INTERGRAL TO THE IGNITION SWITCH. IT ALARMS WHEN KEY IS LEFT IN THE CAR OR IF IT IS BROKEN IT ALARMS FOR ALL YOUR REASONS.

Hi, It is assumed you are using the correct belt for your vehicle? Better still, are you using an OEM belt or other quality belt like Gates, Dayco or Continental? Are all your varoius pullies in good condtion and rotate freely without any excess play in the bearings, Does your alternator have an auto run-on pully? This maybe defective causing belt flutter and rapid wear (im assuming your belt drives the alternator as you have not stated your vehicle type)

repalce wiper motor

Sure. It should also blow when the switch is on Park too. The park circuit is hot in both park and headlight position.

the easiest place to start will be to check and see if you have you take starter fluid and spray it in to your intake if it starts your fuel pumps bad or it has a bad relay possibly even a short in the wire I know Chevys mainly the Blazer was bad for that if it still doesn't start full of one of your plug wires if you happen to have an extra spark plug stick it in the wire and lay on top of the engine where I can get a ground but do not hang on to it it would light you up

run fault codes and look for temperature related sensors.

Check the oil level in the transmission to check for oil leaks . Run fault codes and look for a fault in the TCM unit or wires not connected properly. Have a pressure test done to check for internal problems.

Could be just a need to reset the "check engine light", normally this is accomplished when the battery is disconnected for 15 minutes...If your Lebaron is now running smoothly, have the alternator battery tested for free at most auto parts stores for peace of mind. Auto Zone can also read the check engine light code for free. Tight belt, good tensioner pulley, good alternator, you should be in business. Most likely no harm done when the arc occurred.

87, ouch old iron.....which engine?is it a CARB? engines.ever tune it up, fully? if not why not.?

You take the hot wire to the ignition switch and twist it together with the run wire out of the switch-then ignition is on, just as if the key were turned to on. Then take the start wire that goes out of the switch and touch it to the hot wire to make the starter work. Soon as engine is started, remove the start wire from hot wire and tuck it out of the way. When you want it off, untwist the hot wire and the run wire.If you cannot hot wire it like this, check if there is a security system that has immobilized the car. I don't know if a '92 had a security system.

Like the pedal goes to the floor ?

go get it scanned find out what problem is exactly there free
