Car cuts off while i am driving

You have one of the two issues. One being the battery connection is bad or your car is draining power from somewhere called a parasite draw. It stays running long enough till it sucks your power away all the way. This sucks power while car is off. Second is somewhere you have a fuel blockage which isn't allowing car to breath. Is your carb clean?

the best way to diagnose this is with a live data scan. an engine analyzer is hooked up to the obd port and the car is driven. everything the computer is doing is measured, spark, fuel trim etc. you have to find out if you are losing spark or fuel.

I think it is My Alter I put fuel injectors in it and is still Cuttin off now it’s a 2003

cam shaft sensor faulty, intermittent

My car stopped driving sounded like it was on nuetral didn’t want to run anymore and looks like a lot of oil was spilled from somewhere what does that mean it turns on but doesn’t move

Did you find what the problem was? My 2003 Deville has started shutting off while I'm driving

I am having the same problem with my 2003 deville. I think its a fuel blockage problem. My "check gas cap" was on so i put a new one on. It helped for a day. Now the same thing is happening. It dies when come to a stop EVERY time I stop. Any suggestions?

My 2002 Cadillac DeVille has cut off while driving down the street and will not make a sound no start no crank what could be the problem used to cut off by itself while driving
