-5.0- Posted January 20, 2010 Report Share Posted January 20, 2010 so i bought this 97 sts and its a really nice car, first it had a overheating problem and charging, i figured that out replaced the battery and alternator, and waterpump and now car was running good i did a tune up changed plugs and it was great, drove it for an hour then out of no where cause it wanted to on the highway normal speed it just lost power. it died. after further inspection under the hood the small fuse box i pulled the fuel pump relay one (small grey box fuse USA 965041A) it smelt a little burnt. inside the car i could smell some burning also. just a funny smell not really burning. i got it towed home cause i couldnt hear the the pump purging or coming on when i turned the key. i pulled the codes on the dash 165 695 KM on the car if it matters.

Bruce Nunnally Posted January 20, 2010 Report Share Posted January 20, 2010 Generally PCM codes have to do with the engine computer. TCS are traction control codes. ACM is Air conditioning. RSS is ride control PZM and OZM look llike light / lamp issues. Your codes will be similar to the 1998 codes shown here: http://www.caddyinfo.com/1998eldoradodtccodes.htm B1348 Very Low A/C Refrigerant Pressure B1161: Loss of Serial Data?

BodybyFisher Posted January 20, 2010 Report Share Posted January 20, 2010 Was the battery new? Are you sure that the battery connections are good? As Bruce noted that short to ground is the first one that I would look at. Are there any aftermarket accessories?

-5.0- Posted January 20, 2010 Author Report Share Posted January 20, 2010 No the car is stock not even an alarm that I know of it has power options though. I'm just wondering if there's another relay somewhere in the car like my 90 gt mustang has the one under the seat also and an auto gas shut off/ reset in the rear of the car. The battery was well is new and yes the ground is good I'm thinking somehow the system got over loaded by something like fans turning on or something (car was at operating temp when it died) Link to comment Share on other sites More sharing options...
BodybyFisher Posted January 20, 2010 Report Share Posted January 20, 2010 Fans cant overload the electrical system Check the positive battery cable, it is two wires sandwiched with a lead spacer between them. Make sure that entire joint is clean, take it apart by taking the red insulator off of it. clean it well Check that when the cable to battery bolts are tight, make sure that the cables are tight, sometimes the bolt can bottom out and the cables are not tight. These cars need GOOD current and steady non intermittant power, You need to seriously eliminate that possiblity at the outset of this diagnosis a bad or intemittant connection can cause problems like DTC codes all over the board. What kind of work has been done on this car? Check your under hood relay center, pull each relay and fuse and look for GREEN/WHITE corrosion, that can cause fits, and make sure that the 12V battery cable is tight at the relay center Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

Did you make sure that the socket and the relay were clean?, that could have been your problem, buy some electrical contact cleaner. If you have corrosion in one socket you must pull all the others and check Check the Fuel Pump fuse also You are looking for this type of corrosion, notice how it eats the contacts Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
CarlaValentine Posted January 20, 2010 Report Share Posted January 20, 2010 I don't know for sure whether there are other relays/fuses for the fuel system in your car, but I know there are in mine. There should be a diagram that lists all the fuses/relays, their location, and what they do in your owner's manual. If you don't have one, you can download one here. It's GM's website. You have to sign up, but all that requires is putting in your e-mail address and your car's VIN number. It's the only place I have found that lets you download them for free. http://www.gm.com/gmownercenter/gm/?campaignId=&vin= Link to comment Share on other sites More sharing options...
-5.0- Posted January 20, 2010 Author Report Share Posted January 20, 2010 Yes it seemed clean but I'll for sure get some cleaner and pull all the fuses and clean the up. Thank you I'm on my iPhone right now at work but as soon as I get up I'll forsure download the diagram You guys are really helpfull Friday my buddy is going to come over and work on it with me and were replacing a wack of fuses to be safe Link to comment Share on other sites More sharing options...
Ranger Posted January 20, 2010 Report Share Posted January 20, 2010 I'm just wondering if there's another relay somewhere in the car like my 90 gt mustang has the one under the seat also and an auto gas shut off/ reset in the rear of the car. I think you are talking about an inertia switch. GM doesn't use them. Your pump may be on the way out and overloading the circuit. Link to comment Share on other sites More sharing options...
-5.0- Posted January 30, 2010 Author Report Share Posted January 30, 2010 so it turns out it was the relay and some fuses but now iv got another problem there is a draw somewhere and it kills the battery and im really not sure where to even begin. this is a beautiful car but the problems just never end, its a money pit. any suggestions or should i just burn it and rid of my worries.

CarlaValentine Posted January 30, 2010 Report Share Posted January 30, 2010 I'm sure you have probably already checked the basics.....but just in case. Make sure ALL of your lights turn off after you get out of the car, including any interior lights. Also, be sure the stereo shuts off. Most Caddys have RAP (retained accessory power) where the power windows and stereo will stay on even after the car is off, until you open a door, so be sure that the RAP is shutting off as it should. Also, be sure there isn't anything plugged into the cigarette lighter adapter. Even something as simple as a cell phone charger or a power cord for a CD player can still draw power when the car is off. Also, did you make sure you replaced the relays/fuses with the proper types?

Put a 12v test light in line between the negative battery cable and the battery "post". If you have a draw, the light will illuminate. Start pulling fuses til it goes out. That is the circuit with the draw. Link to comment Share on other sites More sharing options...

CarlaValentine Posted February 8, 2010 Report Share Posted February 8, 2010 I'm sorry for your loss of the car. I was re-reading through this topic and can't help but to think back to my old Chevy Corsica. It had a problem with stalling but I couldn't figure out why. One day while I was driving the dashboard caught on fire. As it turns out, one of the wires to the fuel pump under the car had become bare, and was shorting out under the car. I guess this day it shorted out and caught the fuse box on fire under the dash. I managed to get the fire out (my father raised me to keep an extinguisher in my car) and had it sent to a garage. Upon further investigation, the fire started at the fuse for the fuel pump. I realize a Corsica isn't a Cadillac, but I'm wondering if you could have had a similar problem.

BodybyFisher Posted February 10, 2010 Report Share Posted February 10, 2010 Keep in mind that you were driving a 97 that is 13 years old. I am not sure how many miles on it but at this age, it it going to need replacements and maintenance, try not to let this vehicle sour you, with your nothing but money and headaches statement. If no work or substandard work was done on this car, you WILL have problems as with any mechanical device. If the fuel rail caused the fire, whoever owned this car, should have received a recall notice from GM, as many of us did, if the rail was not replaced, someone dropped the ball. Where is this car located, and where was the prior owner located?

CarlaValentine Posted February 10, 2010 Report Share Posted February 10, 2010 For future reference, whenever you get a car, be it new or used, you should look up any recalls that may have been made on it and be sure to get them taken care of if they haven't been already.
