Use the in tank electric fuel pump to pump it out by jumpering the fuel pump relay socket with the key on. The relay is located under the hood in the fuse and relay center. Unless this is a very high mist of oi to gas you need not do this, just top it off as soon as its low and continue to dilute the gas.

SOURCE: 1999 Cadillac Deville- Won't start!

Check your fuel pump fuse these will blow when the pump is ran with the tank empty. If this does not work you probably burned up the pump. check to see if you can hear the pump run when you turn the key on. Please rate.

SOURCE: 1999 cadillac deville air wont work

There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

How hard is it to install oil pan on my 2000 deville, northstar engine

I worked on a 1999 Deville and to remove the oil pan wasn't to bad to change. All I had to do was Jack up the car and support it.Also remove the negative battery terminal.Drain the oil then remove the torque converter cover bolts and then the oil pan bolts and remove the oil pan.On some model Cadillacs there is also an exhaust cross under pipe that also has to be removed.Be sure not to over tighten the oil pan bolts there real hard to get out if you break one.Your going to have to find out how tight they should be because they all very depending on the vehicle.Most all of your auto parts stores have this information.
