Replacing your Cadillac DeVille DTS electronic shocks with these reliable non-electronic shocks is a simple installation procedure. Cadillac air suspension fails because of rubber dry rotting, and then leaking. Your air suspension compressor will eventually fail because of this. Cadillac shocks in the front fail because of the seals in the Cadillac shock wearing down over time. They eventually leak, losing its dampening ability needed for a safe and smooth ride. Try cadillac dealership for a little more info.

How to install a fuel pump


REMOVAL & INSTALLATION


CAUTION
Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
  1. If equipped with air suspension, the air suspension switch, located on the right-hand side of the luggage compartment, must be turned to the OFF position before raising the vehicle.
  2. Disconnect the negative battery cable.
  3. Relieve fuel system pressure using the recommended procedure.
  4. Raise and safely support the vehicle.
  5. Remove the fuel tank from the vehicle and place on a suitable work bench.
  6. Remove any dirt that has accumulated around the fuel pump retaining flange so it will not enter the tank during pump removal and installation.
  7. On 1989-94 models, turn the fuel pump locking ring counterclockwise and remove the locking ring.
  8. On 1995-98 models, remove 6 retaining bolts around the perimeter of the fuel pump module.

To install:
  1. Clean the fuel pump mounting flange, fuel tank mounting surface and seal ring groove.
  2. Apply a light coating of grease on a new seal ring to hold it in place during assembly and install in the seal ring groove.
  3. Install the fuel pump/sending unit assembly carefully to ensure the filter is not damaged. Make sure the locating keys are in the keyways and the seal ring remains in the groove.
  4. Hold the pump assembly in place and install the locking ring finger-tight. Make sure all the locking tabs are under the tank lock ring tabs.
  5. Rotate the locking ring clockwise until the ring is against the stops.
  6. Install the fuel tank into the vehicle.
  7. Lower the vehicle.
  8. If equipped with air suspension, turn the air suspension switch to the ON position.
  9. Add a minimum of 10 gallons of fuel to the tank and check for leaks.

The air suspention pump is not working


Use a test light to the air suspension pump to see if it is getting current. I assume that the rear end is sagging a bit as far as ride height, due to the pump not working. Also, may try to remove and replace pump, assuming that's the problem, and then when the rear air shocks pump up, make sure there are no leaks after shutting down the vehicle.

Also, make sure that the shut off switch for the suspension isn't flipped to 'off.'

My air suspension will not air up


your air pump has gone out. replace it and make sure none of your air springs are leaking since that could have been the cause for your pump to have gone out. constant running of the pump will over heat it and burn it out.

Air suspension is not working


It just happened to me. I took it to a spring shop and had the air bags replaced with coil springs. It is an identical fit from a Crown Vic and only cost $200.00 total! Too much can go wrong with other parts of the air suspension. The ride is the same.

I want to replace my airbag compressor


I Would go with springs. I understand people enjoying the air ride but I promise it is more trouble than it is worth. Compressors have a 100% failure rate. What will happen is the airbag will end up getting a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag kills the compressor and you have to parts you have to constantly keep buying. With air suspension there is never a permanent fix. I would recommend going to strutmasters.com and taking a look at the conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. And for a very affordable cost. I added the link below so you can check it out. http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm I hope I was of some help Good Luck!!!
