bschelle Posted April 10, 2007 Report Share Posted April 10, 2007 Going down the road my 91 Eldo still dies. Just like I turned off the ignition! It hasn't done it all winter. I am begining to think it's temperature related. I have a fuel pressure gauge taped to the windshield and the pressure is steady before it dies and does'nt drop when it dies or when I try to start it.I drive about 6-7 miles before it does it.No codes show up. I let it sit for a couple of minutes and it usually starts. Today it did it and it took a while to start. It would catch and die a few times. When it did start it ran like it was flooded only hitting on a few cylinders then clearing up. I didn't see any black smoke from the exhaust. Again no codes. I have replaced the injectors, FPR, ignition control module, coil, wires and a complete tune up. What could be causing it to do this? What part is affected by temperature changes? I poked arround the wires from the distributor but it didn't do anything. Link to comment Share on other sites More sharing options...
kev2 Posted April 10, 2007 Report Share Posted April 10, 2007 I will do some checking....First thought waas ICM but you mentioned you changed it.... I know you did use AC Delco, and the Dilectric grease a question is there a remote starter? no security lights (VATS) comming on? Any thing about the dash lights during event.....such as all warning lights come on: as during start? an ign switch would act this way BUT the failure to restart for a while is not typical for that failure, Anither thought would be ECM shuting down I will see if the driver circuits are seperate and protected.

It was a NAPA Echlin cap, rotor, coil and module and I used the grease. No remote starter and when it dies nothing changes on the dash. All of the dash functions as if it is still running.

blue_eldo Posted April 10, 2007 Report Share Posted April 10, 2007 I had a similar problem with my 94 deville 4.9. It ended up being the cam position sensor. It was a real pain to diagnose and a pain to replace and gap without removing the distributor. It did throw a code once in a while for this problem. I was on a trip so it was dificult interpreting the code. Link to comment Share on other sites More sharing options...
Caddynut Posted April 10, 2007 Report Share Posted April 10, 2007 sounds more electrical than fuel. Check Coil connections and make sure they are tight. I would be checking to make sure all of your electrical connector plugs are tight. Sounds like something is loose. 2008 BMW 328xi 2007 Chrysler Aspen 2001 Cadillac Seville STS 2000 Ford Ranger XLT1998 Mitsubishi Spyder Convertible 1996 Saturn SC-11991 Ford F-1501979 Chevrolet Caprice1968 Ford LTD1965 VW Beetle "Herbie The Love Bug Replica** 1961 VW Beetle Link to comment Share on other sites More sharing options...
adallak Posted April 11, 2007 Report Share Posted April 11, 2007 I would replace whole distributor. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
bschelle Posted April 12, 2007 Author Report Share Posted April 12, 2007 I replaced the distributor last night. I let it warm up this morning and then took it for a 25 mile test ride and it didn't miss a beat. Time will tell if that is the final fix. I am having a problem with timing it. The manual says to jump pin A & B on the ALDL and that it is located on the drivers side by the parking brake pedal. I have a connector there but the first 3 slots on the top row of the connector are empty. Logan said the ALDL is behind a panel near the center of the dash but I don't see it. I timed it by aligning the ditributor 45 degrees off of the center line of the engine. It seems to run great but I don't want to have problems by not timing it with a light. P.S. Kev2, did you get a chance to check your ECM info? Link to comment Share on other sites More sharing options...
BodybyFisher Posted April 12, 2007 Report Share Posted April 12, 2007 See this for photo of ALDL, the ALDL is under the dash by your knees when you drive, there is a cover on it, if you get on your knees I think its in line with the steering wheel under the dash, take the cover off. http://caddyinfo.ipbhost.com/index.php?sho...c=5875&st=0 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...

This picture shows A & B are on the top right. I could have sworn my manual showed them on the top left! I will check it when I get home tonight. If the link picture is correct then the connector I am looking at is the one because there are terminals in the top right side> Thanks a million for the heads up!
