Was the fuel filter replaced too?
Also check the air filter, if it is dirty replace it, To check the air take it out and if the problem goes away you know that was it. If that doesn't work let me know and we can go from there.

1997 cadillac sls stalls when driving. Have replaced fuel pump twice, and still have the same problem.

Obtain a listing of your current service trouble codes which may point to the trouble.
More than likely you might want to consider either or both of these possibilities.
1. Replace your fuel filter.
2. Replace your fuel pressure regulator.
You can replace the above yourself if you have basic mechanical automotive skills and simple tools.

3. Least likey is that your fuel pump is working intermittently.
The service trouble codes would likely tell you that.

You might also want to check any fuses or wiring connectors.
Cadillac has fuses under the hood and in the rear trunk area. The Trunk area fuses are behind the carpeted padding behind the rear seat on the drivers side.

Both can be done yourself if your the least bit talented with tools and getting a tiny amount of grease on your hands.

Important: Only Work on these with the ignition turned off and cold. Otherwise fuel might leak on a hot item and cause a fire or explosion from the gasoline vapors.

When replacing both remember to release the fuel pressure first. Their is usually a valve at the end of the fuel rail with a covered scharder valve to do this. Just remove the cover, save in a safe place for reuse. Then with a small nail or similar item press in on the small pin to releive the pressure. ( It's similar to letting air out of a tire ) Make sure to have a rag and small cup to catch any fuel that leaks out. Once the pressure has been released fully, you can put the cover cap back on the schradrer valve. Now you can work on replacing the parts. Fuel pressure is restored when your done by simply restarting the engine.

The fuel filter is located on the bottom of the car frame rail just under the rear driver side car door.

The fuel pressure regulator is connected to the fuel rail lines toward the rear side of the engine manifold cover . If you have nylon rail fuels use the Fuel Pressuer Regulator for Nylon Fuel Rails. If you have Stainless Steel Fuel Rails use the Fuel Pressure Regulator for Stainless Steel Fuel Rails.

See the attached pictures.

Again, wipe up any spilled fuel and let vapors dissipate before restarting the car.

97 sl1 started stalling when 1/4 tank of gas now stalls at 3/4 tank replaced fuel pump and filter/regulator twice runs great when full

It seems that cap of the tank is not letting in air to replace the volume consumed by the engine. Earlier, when it used to stall when1/4 full, there must been less blockage of air but now the air inlet must be really clogged-up,so much so that after being emptied 1/4 of fuel, the negative pressure built up inside the tank is enough to negate the fuel pumps capacity & without gas it will stall the engine which is being deprived of fuel.
One way to make sure that this IS the problem, fill the tank half, do not put the cap try a drive at least for 5 miles & if the engine does not stall, then one can be sure that he cap of the gas tank has to be replaced............sodeep

1995 Cadillac Seville SLS stalls out

It sounds like it may be time for a new fuel filter, try replacing the fuel filter first. The filter has a life of 30,000 miles or one year, if it has not been changed, good chance that it's the fuel filter. Take not that a dirty fuel filter will make your fuel pump run hotter and will shorten the life of the fuel pump which is the more costly repair of the two. Good luck and keep me posted, Be glad to help you get your car running 100% again.
