Wht92STS Posted June 30, 2011 Report Share Posted June 30, 2011 92 STS 4.9 V8 new battery, went to start it the other day, turns strong but won't start, had been starting right up, not out of gas but low fuel light on. It could be a fuel filter or pump. Don't want to pay big $$ to get it towed neither. Trying to find out what it could be to fix my self. Not familiar with Cadillacs, bought this car at a auction. It has almost 200K on it. Not trying to drop loads of $$ in it. Thx for the replies. Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted June 30, 2011 Report Share Posted June 30, 2011 I would still put some gas in it first; sometimes the fuel senders were maintenance items and may be out of fuel before the gauge showed empty if so Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
rockfangd Posted June 30, 2011 Report Share Posted June 30, 2011 have someone turn key on while you have your head at te filler neck. Listen for pump. if pump works listen for tone GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
BodybyFisher Posted June 30, 2011 Report Share Posted June 30, 2011 Buy a fuel pressure gage at Sears and connect it to your fuel rail schrader port to see if you are getting pressure. I realize that you are trying to do this on the cheap, but keep in mind that doing it yourself will always be cheaper. Is the check engine light on?, are you getting any messages?, and check for DTC codes that have been set, you dont need a scanner, go to www.caddyinfo.com, go to HOW TO, go to DTC CODES and follow the directions for your year, and post 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...
KHE Posted June 30, 2011 Report Share Posted June 30, 2011 Put a few gallons of gas in it and see if it starts. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
relaxitsonlyagame Posted June 30, 2011 Report Share Posted June 30, 2011 Check for spark too. From what I remember, the ignition module in the distributor would bite the dust every now and again on those motors. PITA Link to comment Share on other sites More sharing options...

relaxitsonlyagame Posted July 3, 2011 Report Share Posted July 3, 2011 I remember that on my 85. In the center of the distributor cap Yup. Easy to replace, but expensive part for what it is. Went twice on me in the 100,000 miles I had it. The part always picked the worst times to not work and after the second one I kept a spare in the trunk.

eddiehill Posted July 11, 2011 Report Share Posted July 11, 2011 I would hook the scanner up and check for rpm, if no rpm the computer will not do anything, no rpm no spark no injector paulse = cam or crank sensor. you need special equipment to check a no start problem. unless u just start changing parts. no offence, check fuel pressure as well. good luck.

lyev Posted July 25, 2011 Report Share Posted July 25, 2011 Didnt they only start making STSs in 2005? Dont think they came with a 4.9L either. Actually, I think it must be an SLS. Link to comment Share on other sites More sharing options...

Actually this car is a Seville with the STS trim level (SLS was also a trim level with this model); you are correct that the model STS began in 2005, but his description is also accurate. And back to the original poster: all good advice, make sure you've got gas (and you might even open the throttle body and add a cap full of gas and see if you get an engine firing condition).
