Question about Cadillac Eldorado

1 Answer

Can anyone explain why my 1993 Cadillac Eldorado wont start after it sits overnight? Also, why does my interior lights jump on sometimes when I hit a bump then turn off when I hit the door panel. My car will start all day without a problem however, in the morning it won't start without a boost. As soon as the cables are put on the battery and a light accelaration from the booster i turn the ignition and the car crank instantly.

    My mechanic replaced my starter. I think he also, cleaned the gasket which were full of black stuff. So far, its been starting everymorning. The starter had never been changed.

    The door was adjusted it was not lined up right. Now it is aligned with the sensor in between the hinges. Somewhere in the ballpark. Does this make sense. I'm not mechanically literate.

Cranks and starts are two different things.
If it cranks but won't start it could be loosing fuel pressure overnight.
If it won't crank in the morning, you could have a bad cell in the battery or something draining the battery overnight. Such as the interior lights coming on and off.
The light problem could be the door ajar sensor in the door latch.

SOURCE: car not starting after sitting over night or after

Sounds like you have something draining the battery down. You probably something staying on thats not supposed too. I would start with the brake circuit.

Welcome to Fixya. There is a good possibility that is what has happened. When the cables are attached right, you should only see spark when you first place them on the battery. And at then, the spark is very small, if any. Sadly, if you have did this, it may have caused severe problems with your vehicle. You have a hot side and a ground side. Hot is red and ground is black. More then likely, you will now need the car scanned on a computer to figure out the damage. It is the only way to do so. Even though it cost a lot of money, it can determine the exact problem. The car needs fire, air, and fuel to start. Your starting system includes the battery, terminals and wires, starter, and your ignition module. You need to make sure your battery is not damaged and it is holding a charge. Make sure the terminals are cleaned and connected good.

SOURCE: the car won't start; lights,

Check the starter and the starter relay or fuse. A client of mines car was doing the same thing, it ended up being two issues, the starter not working anymore, and a relay that was bad. If I am not mistaken everything should be labeled in the fuse box under the hood and will tell you where the fuse/ relay is for your vehicle

Grab some refrigerant gauges and take readings. If the low side has more than 40 psi or so of pressure, the low limit switch will close and allow the compressor to run. If there is indeed low pressure causing the compressor not to run, you will need to flush the system after eliminating the source of the leak. If the a/c compressor has never been changed, it is probably the source of the leak.

Why does my 96 Cadillac Eldorado battery keep discharging?

First step have the battery tested, a bad cell can cause a internal drain and kill the battery, if the batt is ok then check for interior lights like visors that stay on or interior light that come on by themselves at night due to defective door switches.

My 93 cadillac wont start sometimes

These cars had issues with the antitheft system. When the system faults, the starter will get turned off. Normally indicated by a light on the dash that says SECURITY or ANTITHEFT. This link explains the problem.

My 1994 eldorado wont start the car turns on and the lights go on and it just goes click click. I tried jumping it and it still wouldnt start. Does that mean I need a new starter?

These cars did have problems with the antitheft system. When this system fails, the car "thinks" it is at risk for theft, and disables the starter. I would look into this before you change the starter. This link explains.

93 eldorado stalled and wont start again after engine wash

Since you said it stalled out first, and then wouldn't start, we would assume that these are related, but not necessarily. If they are related, the bad or discharged battery would not explain both as the alternator would have provided power to keep it running. Loose or corroded battery terminals or wires that provide power to the computer and ignition would. A neutral safety switch that assures that it is in neutral or park may be better or it may not be in neutral or park, again not explaining why it would stall. It is always wise to disconnect the battery cables when spraying your engine compartment. Check your main fuses as they may have blown from the water grounding something out.
