No crank...nothing!

Hey everyone...i think i have the similar problem that Carla has! This morning when i was going to work i turned the key and the "Monotoring system ok" message appeared....but when i tried to start nothing happend!

Ran a check for troublecodes through the climate control panel....no codes whats so ever!

The battery are only 1,5 years old and the terminals are greased in and tightened!

Had a friend to drive me home tonight and we tried to jumpstart it but there are no response!

The voltage are good and all cables including groundcables are recently cleaned and greased in!

The car have shown no signs of a bad starter or a week battery ever, it ran just fine until i got out this morning and it was dead!

I have tried to move the gearshifter and turn the key but it didnt help att all...its just dead!

The only thing i can think of right now are the gear shifter mecanism that have been a bit tricky sometimes...one time it wouldnt go from P to D but after a couple of minutes it finally came loose!

Another thing that came in mind today are that i put in a resistor between the two thin cable that goes to the VATS system computer...maybe it have fallen off? But in that case it would appear "Theft deterrent" Message in the display...right? Itss no messages whats so ever!

Im thinking either the starter or the gear shift mecanism..but woouldnt that set a code?

Thanks

no codes correct?

The starter would not set a code

And yes, if the resister came loose, you would get that message and a code may set

When you turn the key to start, do the lights dim at all?

Never assume that the battery is good at any age, I would load test it

The positive cable is a sandwidge of two cables one of which goes directly to the starter, and one that goes to the relay center. I would take the positive cable apart and clean it good. The red insulator must come off to clean it good, and make sure its tight

That is where I would start, to eliminate those items, no click at the solenoid is telling

No codes att all...that is correct! When we tried to jumpstart it we also tried with a powerful battery booster but absolutly nothing happened! The starter have always done its job so its strange if its bad!

Only problem that i have had are the gear shifter that refused to shift!

But i will get it towed to the car shop next week and let them check it!

The gear shift refusing to shift out of P could be related to the brake interlock, going from P to D

Take apart the positive cable, after removing the negative cable.

We need to eliminate the easy things first

The cables are the easiest thing to look at, we need to make sure that the inside of the positive cable is not corroded, it could look great on the outside but the inside could be corroded

Now, if that is good, you can check the starter relay. I believe that the security system enables the starter relay, the starter relay causes the key to engage the starter solenoid, if the starter relay is bad, you won't get anything not even a click, even though the security system is saying all is OK.

You might have a look at the starter relay and reset its connections also

If you heard a click, we would know that the solenoid is engaging, but that is not happening

UPDATE!

Problem solved!

I cleaned the terminals once again today and used original battery grease...not cobber paste! Tightened and remowed all fuses,cleaned them and sprayed with contact spray!

Also checked all fuses in the trunk!

Checked under the dash if the VATS cable had fallen off....it hadnt!

Sat my self behind the steering wheel and tried....and it fired up:)

Waited until the ngine was warm and shut it off!

Tried to start again and it did!

Shut off and started 10 times more...no problem!

So it was just an connection problem...its strange... last summer i cleaned and greased up all ground wires with cobber paste including the battery terminals!

But now i remowed the cobber paste from the battery terminals and used original battery terminal grease...that must have been the problem!

Thank you guys for the quick help!

Texas Jim: Cobber paste is probably supposed to be copper paste. Copper paste is grease with small copper flakes in it. Commonly use here in Sweden to prevent screws from sticking in high-temp places, as for example exhaust manifolds. Also sometimes to prevent wheels from sticking (happens over here with all the annoying salt they put on the roads in the winter), although aluminum paste should really be used for that if you have aluminum rims. Not sure if those kind of pastes are common in the US or not.

Roger: I really hope that you did solve the problem. However, when my starter relay was acting up (see my post in Carla's thread: http://caddyinfo.ipbhost.com/index.php?showtopic=34957&pid=181433&st=45entry181433 ) it was either perfectly fine, not working at all or working after some tries. Sometimes holding the key in the start position for a few seconds helped. I would hold the key, and suddenly the car just started normally.

I am just adding this in case you are unlucky and it stops working again, but once again: I hope it is solved already!

Thank you hjb981!

Its probably best to replace this relay just in case!

Do you have a part-number and where are this relay located in the car? Its a STS 95!

I checked Rock-Auto but i couldnt find the "starter relay"

Thank you!

Texas Jim: Sorry for the spelling...its copper not cobber:)

I think the relay was far to the left or right under the hood, and a bit down.

Check this:

http://wiki.answers.com/Q/How_do_you_change_starter_relay_on_1996_Cadillac_Eldorado

and this:

http://forums.automotive.com/70/1002112/engine/94-cadillac-seville-starter-relay-location-startin/index.html

The first one is similar to how I remember it on my '97 DeVille. I don't know how often these things fail. Anyway, I got mine from a dealer (in California) and unfortunately I have no idea what part number it has.

Ordered AC Delco 158719 starter relay today from Rock-auto...fits Cadillac 1993-2011 according to info! Also ordered 2 hood lift support for the hood...mine are getting tired!

According to Haynes the starter relay are located in the fusebox next to engine but i saw on a eldorado 1992 that its located in the wall in front of the drivers door...is it same on seville 1995?

My 1995 Eldorado/Seville manual describes the Starter Enable Relay as "Taped to the body main harness, 9 inches rearward of front edge of LH rocker panel." I never had to dig the thing out, so I can't help with any specifics. See drawing.

  • 2 weeks later...

Update!

Today i replaced the starter relay and i hope that was the problem! The car has started every day for nearly 2 weeks but yesterday when it was -12 degrees celsius outside the same thing happend! No crank...

But today saturday it was +2 degrees celsius outside and it fired right up!

For those who dont know where the relay are located its under the plastic rocker channel on the left drivers side..remowe the plastic cover and under there you have a bunch of electric cables that goes from the backseat to the front! The relay are under these cables towards the front!

Partno: 12193601 ac delco

The old relay was a bit wet and i think that moisture had made it non functional when it was cold outside! But now its a new relay there and i taped it good so it stayes tight!

Thank you hjb981 for the tip!

Glad to see you took advantage of the warm weather to get the job done. :P :P :P

I hope that was the fix.
