disciple3rd Posted August 6, 2006 Report Share Posted August 6, 2006 I have a 1992 Cadillac Deville I have had the engine rebuilt and runs good, but after the fuel level gets to 3 gallanos it will cut off and i have to restart the car. What do I need to do to fix the problems. Also I forgot how to check for codes on my Caddy. I forgot which buttons I need to push prior to start.

PAUL T Posted August 7, 2006 Report Share Posted August 7, 2006 I do not let my 92 Deville get below 4 gallons. I would just keep more gas in it. When your gas gets that low it could slosh around the tank and possibly move away from the pump and just suck air causing the engine to shut off or stumble. I would just keep it above 5 gallons. Check codes by pressing and holding the "OFF" and "WARMER" buttons on the climate contril panel. Link to comment Share on other sites More sharing options...
Ranger Posted August 7, 2006 Report Share Posted August 7, 2006 Common problem with '92's as Paul said. I had a '92 but never expirienced that. Guess it's because I never let it get below 1/4 tank. Link to comment Share on other sites More sharing options...

How can I make my car run smoother, also if I buy new struts for my car would that help with my suspension. Oh one more thing should I get my transmission looked at. My car sounds real powerful, a little rock at times. I drove my car from Texas to Spokane Washington, runs great on the freeway but on the regular streets i Can hear some knockoing any suggestions.

thu Posted August 7, 2006 Report Share Posted August 7, 2006 I had a similar problem in my 93 Deville, which is pretty much the same as a 92. The problem was either a weak pump or busted baffles inside the tank. My solution was to replace the whole thing as an assembly. Found a replacement gas tank off a 1992 Deville for $75 complete with fuel pump. The problem disappeared forever. I can run it down to less than two gallons with the replacement tank/pump and make high speed turns - the engine keeps running without interruption. With the tank dropped and the pump pulled, you can look inside the tank. There's a reservoir where fuel will collect. Looks like you can run with less than a quart of fuel and make hard stops and high-speed turns and keep the fuel pickup tube completely immersed in fuel, no sucking of air. My experience bears this out. Before the tank swap, the car would quit with less than six gallons in the tank. High speed turns and sudden stops would make the engine quit. When I replaced the tank, the replacement tank was completely empty (I know, I checked thoroughly), put something less than two gallons in it, and took it for a test drive. She ran like she was designed to. High speed corners, sudden stops. and hard acceleration - nothing would make the symptoms come back. After about 50,000 miles of driving, then problem has not returned. I also have let the tank run almost dry since tank and pump replacement. If your car quits with more than one or two quarts in the tank, I'd say something is wrong with the tank or the pump. When I replaced the tank/pump assembly, I planned to keep the car until the wheels fell off. So, it was worth the trouble to replace the whole kitten kaboodle. The problem could have been the tank or it could have been the pump. It could have been both. In any case, replacing both covered a myriad of possible problems. I'm glad I did that. 2003 Seville STS 43k miles with the Bose Sound, Navigation System, HID Headlamps, and MagneRide 1993 DeVille. Looks great inside and out! 298k miles!

WarrenJ Posted August 7, 2006 Report Share Posted August 7, 2006 I think thu's suggesstion is tops. It covers most of your bases (inexpensively). There isn't a Yugo on the planet, much less a Cadillac, that shouldn't run properly with a quarter tank of fuel. Regards, Warren There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises Link to comment Share on other sites More sharing options...

thu Posted August 8, 2006 Report Share Posted August 8, 2006 Don't forget to do the simple diagnostics first to be sure it's not something simple. Check fuel pressure. When ignition 'on' (engine stopped), you should read about 40 PSI. It should hold this pressure for quite some time. Needle should be rock steady. Fuel pressure should be similar with engine running. Pressures substatially less indicates bad pump, restricted fuel lines, clogged filter, or bad FPR. Check/replace fuel filter.
