Hi I have a 2003 Cadillac Deville Dts. and since Nov 2007 it has been stalling. It seems to happend 1 evey three-four weeks. Then if i leave it off for a while it will turn back on wiht no problem. Or if I turn it off open all doors and let itslef reset it will start. It is soooo weird. I have taken it to Cadillac and they don't know whats wrong. I have already changed out the Cam sensors and and the torque converter but it is still happening. The guys at the dealer our clueless and say the car is perfect. NO IT'S NOT if that was the case it wouldnt turn off .. Please someone HELP !!!! I have a baby and I am scared this might happen while i'm driving. Luckily so far its only when I get in my car and turn it on.
 
Oh yeah and now it's leaking oil ..AHHHHH !!
  I've only had the car 1 1/2 and it has 75000 FYI.

I have a deville, it wont start, i have checked into many possibilities, like checking for spark, (there is) New fuel pump, filter, and strainer, put new alternator in, new battary, so now i am looking into the fuel being the issue at hand. There is fuel going into the fuel rails, when they are compressed fuel is shooting out, so where it goes after there may be the problem? That i dont know. When there is fuel put directly into the throttle body, it will start up, then die when there is no more fuel in there, but when turning it over i get nothing along with that, we took the throttle body off, and under there are two pipe like things that go strait up under there, one of them are clean and have no grime or anything, the other however has sludge like stuff inside it,and when i attempt to start it that stuff sprays out, I dont know much about cars so im hoping someone will come across this and have an answer, I have ran outta things that people tell me it could be that its not...so im at a stand still and really would appreciate some advice...besides getting rid of it, ive put too much into it to want to do that. Please someone help!!!

I have a 1998 Cadillac Deville and for the last two months it has been stalling at stop signs whenever it is raining. Garage says its wiring but to hard to track. Any Ideas?

Crank Position Sensors. There are two of them, replace them both. If it truly is water related, the connectors for the sensors might have a problem.

98 Deville stalling by 98slab

Once the car is started, there is no problem with that. As I'm driving the car, every once in a while it would just stall out. I'll pull off the road and restart it with no problem. It wont really happen again until the next time I drive it. There is no check engine light or anything. I tried to get a diagnostics but couldn't because the check engine light wasn't on. Other than that, everything works as it should. Can anyone help me with this?

I didn't, but thank you for the advice. I'll look into the price. I'm not a mechanic so do you think it will be better to have dealer do the work or buy the parts and take to my mechanic?

I'm a cheep SOB, but that is something I've never had the guts to do - buy parts and ask a shop to put them on. You are basically asking him to reduce the price on the job by about 10% or more, which is his discount on the part when he buys it and charges you retail.
