I just wanted to know if my 2000 crown vic is jumping time and what that really is. When I put my key in my car and turn the key in the car starts and sometimes it doesnt but when it does start it just kills out, my engine is turning over, ive already had someone drop the tank empty it clean it out clean all injectors change the fuel pump all because it sounded like it wasnt geting gas to the engine all that didnt do anything, they said my car is running on 4 cylinders instead of eight though, I really dont know what to do ohh and I aslso bought the coumpter piece to see if that was the problem that was 250 dollers wasted, please help! And its not getting commpression

What are the compression readings, do them wet and dry, a wet test is with about a couple of tea spoons of oil in the cylinder, what this does is it will seal up the rings for the test, if any comp was low on the dry test and it comes up wet, there will be a valve problem to look at.

If the Crown Vic had jumped timing, you would m=know it because a valve would be through a piston.
