connorjon Posted September 17, 2009 Report Share Posted September 17, 2009 Hi, I just decided to post this to see if anyone had any idea what could be going on with my car. I own a '99 seville SLS and it seems that about 20 minutes after I've driven it and the engine is still warm it takes about a half minute to start. It will just keep cranking and cranking. If the engine is cool, the car always starts right away. Also, sometimes once the car has started, my rpms will go really low and then shoot back up and sometimes the car even dies (only right after ignition.) Everything seems to be working perfectly when I'm driving and I've never had any problems other than during startup. This problem has been going on for about 6 months and I was wondering if it sounds like my FPR? Any help is appreciated! Link to comment Share on other sites More sharing options...
BodybyFisher Posted September 17, 2009 Report Share Posted September 17, 2009 Yes it sounds like a FPR Pull the vacuum hose off of it and look for fuel spitting from it both with the engine stopped and with it running any fuel at all replace it. Also, check for codes, go to the top of this page, click HOW TO, then DTC CODES, look for your year and follow the directions and post the codes here 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...

That's another problem that I cant seem to figure out.. It limits my car to 90 mph and I get the Speed Limited to 90 message in the dic everytime I start the car Link to comment Share on other sites More sharing options...
BodybyFisher Posted September 17, 2009 Report Share Posted September 17, 2009 Check your FPR first, we will try to figure out what that code is. Hard starting warm/hot is usually an indication of a bad FPR 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...
BodybyFisher Posted September 17, 2009 Report Share Posted September 17, 2009 Here is some info on the P1652, this is definately your reduced speed problem. http://www.gearchatter.com/viewtopic10122.php 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...

I'm going to try and get that FPR taken care of and then I'll look into the PCM Link to comment Share on other sites More sharing options...
BodybyFisher Posted September 17, 2009 Report Share Posted September 17, 2009 That code has to do with the PITCH UP/DOWN of the car. It detects when the brakes are mashed hard, the nose dive, and it FIRMS up the suspection, it also does the same on hard acceleration, when the nose comes up hard, it FIRMS the suspension. Something is wrong with that system 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...
JimD Posted September 17, 2009 Report Share Posted September 17, 2009 I've checked the codes before and only had the following: ABS C1252 ABS C1253 ABS U1255 PCM 1652 None of these trouble codes are related to your starting issue. Your P1652 and the two C codes relate to a data link between the suspension control module (CVRSS) and the powertrain control module (PCM). And these three codes are behind the "SPEED LIMITED" message. I would try clearing all the codes and see which codes, if any, show up after a test drive (or several test drives). It would also be a good idea to separate the starting issue from the "SPEED LIMITED" by starting another thread. Jim Drive your car. Use your cell phone. CHOOSE ONE !
