Cadillac Deville Starting / Stalling Problems

Comments

  • My '89 Coupe de Ville with 77,000 miles apparently has a blown head gasket. (It tested positive for hydrocarbons in the coolant. 85!) I'm told to either get a rebuilt or a used engine. Think I'm throwing good money after bad? Is there no "easy" way to take the heads off and replace the head gasket? It's obviously not like the good 'ol days when you could do it in your garage on Saturday morning. I can't seem to find anyone that wants to tackle the job. Everyone says $1500 to $2000, or more! Any suggestions?
  • i have checked the battery....it has a brand new starter. wont make a noise when u turn the key over.....please help me its a 1992 cadillac deville

    First thing to check is both battery cables. Check where both are bolted down, both ends. Check that there is not extensive corrosion INSIDE the rubber insulation. A cable can rot away inside there where it cannot be seen.

    Next place would be the security system. I think this year had a lot of problems with a small wire inside, or at the bottom, of the steering column that breaks. This is the wire that takes the signal from sensing the small 'pellet' in the key to the system that controls the security system.
  • Will this work on a 96 4.6 deville also? keeps saying service emissions, rough idle but runs good.
  • i have a 2001 dts 78,000 miles serviced regularly at dealership, noticed lately idle is low at start up sometimes, within a month car refused to start twice because idle was at about 400 to 500. sometimes while driving idle will be high around 1500 to 2000 with foot off gas pedal and u can feel it pulling at a complete stop. sometimes car runs fine with no problem. check engine light came on and the codes were 506 and 507. ive cleaned throttle body but not iac also was wondering if it was a vacuum leak could the idle fluctuate both low and high idle sometimes??? please help with any suggestions. thank u very much
  • when I try to start I get a message, "Starting disabled, wait 3 minutes". Sometimes it works, sometimes not. Is this the chip in the key or the computer going out or something else.
  • Hello gang. I have been trying to get an answer to this problem for about a month now from all over. My 2000 Deville (Base) will not crank. Everything works, battry new, replace key cylinder, crank sensor A & B, ignition switch, starter and starter relay, and check all connections and grounds (to the best of my knowledge). There appears to be a break down between the starter and gound. If you connect a separate ground from body to starter the engine will turn over slowly. If you run the additional ground to the body, it barely turns the engine over I used jumper cables and also tried at the battery ground. The only codes were P0335, P0340, P0385, which all point to to crank and cam sensor curcuit, all of which seem to have tested fine. Even used a scan tool not a Tech 2 (loaded with updated software, except for the GM high priced subscriptions) a friend has, but could not get a crank request. Any help would greatly be appreciated. I do have the factory service manuals. :confuse:

    You've thrown a lot of parts at this problem without much success. I think it's about time to tow it to a dealer.

    A problem with my wife's 2005 Deville - I like to bring up all the displays occasionally. The voltage was continusly bouncing between about 13 and 15.5 volts. Staying on any voltage only a few seconds.

    What I found was the negative battery cable, under the read seat, grounds to the body there, right next to the battery. It was a little loose, plus the red paint (car color) was under the cable. I removed the bolt, ground the paint off with a Dremel tool, and scraped the cable end, etc. This totally stopped the voltage bounce.

    If you haven't done it, you sure need to check this battery ground back there!
  • i ws told that the solenoid in the tranny of my 2000 deville needs replacing. will that cause a leak around the seals?how much for the repair
  • bolivarbolivar Posts: 2,316
    First off, I don't think a solnoid problem would be related to a leak problem.

    There are 3 solnoids in a Northstar's tryanny.

    There are A and B shift solnoids. There are simple to replace with only the pan being removed.

    There is the solnoid that does the 'lockup' for the top gear in the tranny. You cannot get to it by just dropping the pan. The motor and tranny usually are pulled out of the car to get to it. This is known as the $40 part buried $2,000 deep in the transmission....

    There is a diffferent error code set for these different solnoid failures.

    The body control module is located in the truck attached to the upper back seat. you must remove the cover to get to it. They are expensive new, but mine went bad and I found one at a salvage yard for $35.00 which works great. I hope this info helps you clewisl

  • My '95 deville stalled 1/2hr after running. Is it gas or spark? I was ready to perform expensive parts replacement but if it were spark it should be backfiring/missing, right? I ran 3/8" hose from PCV fresh air inlet to driver window & hosed starting fluid @ stall...guess what!!! (ran out of starting fluid). stopped to get more fluid & fuel, opened gas cap..WHOOOSH. Suction when cap opened, hmmm. LEFT FUEL CAP LOOSE. Haven't had a problem since. (200+miles).

    My 2000 DHS with just 40,000 miles on it was occasionally stalling out at stop signs and rarely when driving at moderate speeds.

    I had the dealership replace both crankshaft position sensors and the tech also suggested replacing the fuel filter. I did both.

    1100 miles later, the car is running perfectly and hopefully it will continue to do so.

    It was missing and if you babied the gas you could keep it running bout 45-50 mph. I had a friend look at it. They said dist cap had a hole in it. So I changed the dist cap,coil,rotor button,plugs and wires. It started up ran bout 5-6sec and died. Now it will turn over but will not start. I took fuel filter off its fine. I replaced it anyways. Any thoughts,help ideas would be great!
  • I got in and drove to a store, when I came out the car wouldn't start. After waiting a while, I was able to start the car and drive home. I let the engine cool down for a couple of hours went back out to start it and it did the same thing. I sat there for a while turning the key into the on position for a few seconds and then trying to crank it again. After about 3 minutes, the engine turned over and started just fine. I took it for a drive, came home, shut the engine off, and tried to crank it over again. It worked just fine, I couldn't repeat the problem. I replaced the battery a few months ago and just checked it again and all of the connections. Everything there seems to be okay. Does anyone have any ideas as to what this might be?
