We own a 1992 Cadillac DeVille, and love it. It currently has 280,000kms on it, and we've done the gas tank baffle repair, and replaced the rad hose. We had the air conditioner retrofitted, and new, sensor free shocks installed, removing the bulb from the dash warning light. Car is beautiful to drive and we love. It does, however, have another problem which gives it a personality. We have taken to calling it 'Cruella' (as in DeVil) because sometimes it starts and sometimes it doesn't. If we wait 3 minutes, it will usually start, and we've been told this is a security system problem, a key chip problem, or a ignition cylinder problem. Since these repairs are more than we can afford at this moment, we build "wait" time into our outings so we can wait for our recalcitrant witch to reset. Hopefully, the problem remains intermittent. Does anyone know about replacing the keys for a Cadillac?

I just purchased a 1992 Sedan De Ville, and the truck pull-down was unhooked because the old lady that had it didn't like it. I don't know where it is or how to hook it back up, could you help me out. My email is bigmann_tkl7755@yahoo.com.

PS: I LOVE MY CADDY! Definitely the way to go, but you're right about the parts being so expensive, but I think it is worth it.

Hey I love my caddy. I've got a 1992 Cadillac Sedan Deville. It is my life. I have put over 4 grand into her. She runs great!

I have the same gas tank problem that everybody else has. But I put performance parts on mine, and they're way more pricey than the dealer.

I use mine to drag race the streets with, and now I'm having tranny problems. Well if anybody knows where to get performance parts, hit me back?

The only reason your having tranny problems is because drag racing puts a lot of stress on a tranny, especially an automatic one that was build for a smooth ride, not harsh quick gear changes. Anyway if you disconnect the TPI unit you will free up some more horsepower and torque, I haven't done that to my Caddi considering I don’t drag race. It has more than enough stock power. But I’m all for street drag racing in a American car just keep crushing those cheap plastic econo Honda's.

I bought a 1992 Cadillac DeVille recently with 55,000 miles on it. Yes, the repairs are expensive! The digital dash literally crashed and burned ($800 at the Cadillac dealer, my mechanic wouldn't touch it!). The brakes failed ($800 - new master cylinder, and many other brake related parts). New transmission (got this under warranty thank God) and finally a new water pump ($500).

I bought the car for my 17 year old son... he loves it and thinks its really cool... we especially like the gimmicky light monitors and opera lamps. It's in beautiful cosmetic condition including the leather interior which is pretty much flawless including the driver's seat.

The stalling problem mentioned is interesting and it has stalled on us twice for no apparent reason in the three months we have had it... now I know to keep the gas tank relatively full (not easily done... she's a thirsty beast averaging 15 mpg.)

I bought a 1992 Sedan De Ville. It had some front end damage. I fixed it and had it parked for a month or so. It ran great before I parked it, and then when I went back to start it up, it started fine. But while I was driving it, you could not give it much fuel at all, it would not take it, it would just cut the power out. I had the fuel tank cleaned, new fuel filter, cleaned the lines out, injectors cleaned and also had someone change the fuel pump. Don't know for sure if they did or not, because it is doing the same thing, but after cleaning the things up, it runs a little better for a couple days, and then back to the same way... IF ANY ONE COULD HELP ME?

Get your ECM or ESC module check out. One or the other could burn out and confuse the engine.

My 92' DeVille would not start. I left it sit over night, pumped the gas pedal and it fired right up. I know this is not how you typically start an injected motor.

Later, I drove it eight miles, shut it off with no problems, ate dinner, then started it without having to pump it, and drove for two miles; it stalled and will not restart. It says there are six gallons of fuel. Having read some of the symptoms, I think if I top off the tank, this pile might make it home?

I have a 1992 Cadillac Deville. Beautiful in my eyes. Great interior, exterior and rather low mileage, 128,000.

I am having a similar problem with the fuel pump as I suspect. The car starts and I will let it run for about 20 minutes, and then it just stalls. I speculate it being the fuel pump going out because I think it overheats and then shuts off, causing the car to die. Now if I shut it off before it dies and try to start it up again, it will not start back up until around 30 minutes later. Thus my speculation of the fuel pump because it has cooled off, so it will start up again. This is critical for me to find out as this is my only car and I NEED to get her fixed. I'm scared to drive anywhere, because I don't want the engine to just stall and not start, because I have two children and it scares me.

I have run the code test, but I misplaced what codes were given, and I'll need to run it again. I'm not sure if it is the low gas in it. I know I don't have more than 6 gallons in her, but my car never acted up before. ANY help you may have would be greatly appreciated! You can contact me at hotchic1011@yahoo.com. Thanks for reading, and I hope to figure this car out.

I have a 92 Cadillac. It has a 4.9. The car is in great condition. I love it.

When you start it up, it runs rough and has no power, so I thought it was a tune up, so I did the plugs, wires, cap, rotor, fuel filter, and the catalytic converter, and still it's the same. All the fuel system has been cleaned, and it's no better. I can't figure out what codes are coming up.

Please help me, I love this car and I don't have a lot of money, but I will do anything to fix it. It's my only car, and I got it from my Grandma.

Y 92' DeVille runs rough on hot days, and after 20 minutes or so of running rough, she begins stalling at stops, eventually leading to total engine shutdown. Believing it's the fuel pump, I began searching for mechanics... Never got a straight answer from them; now I believe I can just clean the fuel system, then replace the tank, and it should be fixed. If not, then it could be under the hood. EMS, TPS, MPR and so on. Regardless, when you look hard enough, you can fix these cars pretty cheap.
