Cadillac Repair: stops while driving, gm vats, intermittent problems

Question
I have 1999 cadiliac deville i changed the fuel pump because it died ( wasn't coming on), changed spark plugs and wires. I had no problems before this fuel pump incident. Now while driving it will shut off and not start i will wait for a day and it will run fine and do it all over again. This has been going on for about a week.

Answer
Hello,

As much as I would like to help you, I can't anymore than you have done by changing parts on a guess. Intermittent problems are horrible to diagnose because they are difficult to recreate at your convenience.

I can tell you with cerainty, this is not a GM VATS anti-theft problem, because if so, the engine would not start in the first place.

Possibly, there may be trouble codes stored in the computer. You can take the car to a service center and possibly, they may find a diagnoses for you.

Anything without physically being at the car on my part when you are having the problem would only be a guess on my part which could be expensive to repair and you still don't know if the problem is fixed until you find the engine stalls again.

To save you money though, don't go to a dealer. I have found from experience, they too just guess at the consumer's expense.

Good Luck!!
