I've never had problems with the freeze plugs but I have had to put 3 water pumps on my 91. That has always caused a, "bad water leak." Sometimes comes out from under the pulley and sometimes comes out from under the pump gasket. The pump/gasket is about 12 inches across and 6 inches tall.

I had the same problem with my 94 deville except it was just one of the fuses under the hood but i alos know that sometimes when this happens your ground wire (which should be under the car on the gas tank has came loose. I would check these things first. As for your fuel door i have the same problem so i dunno The gas sensor is located on the fuel pump inside the gas tank. One day my deville ran out of gas when it showed 4 gallons. A week or two later the fuel pump failed. The shop said I needed a new fuel pump. 700 Bucks. ouch

How can I make sure it really is my fuel pump that is bad in my 96 Cadillac Deville?

If it is the fuel pump, you can take the fuel line off, place a cup or jar at the end of the line. Turn the ignition switch to the ON position and turn off. if there is no fuel at all, there is a big possibility that it is the fuel pump. But it could be a fuse, fuseable link, or broken wire... If there is fuel in the cup or jar you will need a fuel pressure check. At this point if you dont have the tool, You more than likely will wont to have a Mechanic that knows how finish checking. If the pressure is not strong enough, it is the fuel pump.

***The problem you're experiencing is a malfunctioning ECM. It's the "body computer" for your vehicle and I've been through the same experiences, not to mention erratic inflation of the load leveling rear suspension. It can be attributed to the ECM going bad but there could be worse underlying causes such as a bad ground on the vehicle or moisture reaching the computer..both of which would continually cause ECM failure...i.e. you'll end up replacing it more than a few times and it will keep occurring with time. Chasing down a bad ground (the car has SEVERAL) can be costly or nearly impossible. It might just be time to part ways with it. I did with mine and it was rust free and otherwise perfect.

94cadilac deville the engine misfires when you first start it up when it is cold runs better warm will miss or drop a cyl. when I use the blinker or use the power windows ect. bad ground HELP PLEASE?

On the 4.9L Cadillacs & 1990 4.5L's, you need to follow the negative battery cable where it mounts to the side on the engine block (next to the starter). You need to take off the negative cable & clean not only the terminal lug, but the stud that bolts into the engine block. Remove any star washers you find on the lug, they are part of the problem.

The cause of the misfire is that a loose or dirty connection at the ground wire will cause a voltage drop on the distributor circuits. As little as 1/2 volt drop at the distributor, will cause the computer to lose the distributor signal & cause the engine to misfire... any electrical load (power windows, blinkers, etc) will increase the voltage drop at the distributor circuits & cause the computer to lose it's sync with the distributor. An easy test to start the engine cold, then rise & lower ALL your windows at the same time. If the running of the engine is affected, clean he main ground on the engine block. We call it a "Cadillac ground service"

Most flashers and or fuses are located on or near the fuse panel under the dash on the drivers side. , EzForJesus

PS the flasher itself may act as a fuse or the fuse may be intergrated to interact with other components as well. If your fuse panel is not marked take them out and check them one at a time and put them back making sure not to put the wrong fuse in another plug or socket.

How do you replace the power antenna on a 2002 Mitsubishi Montero Ltd?

I am also trying to change my antenna on a Montero Limited 02 and found a antenna on EBAY but you have to replace everything. BUT a Better Idea is the one I found on WWW.CARSTEREOHELP.COM On this site, they say it is possible to change out the antenna whip only. This is the weekend, but I plan to pursue this option on Monday. I'll use my $30.00 antenna on some other car!
