- 1997 Buick Skylark Custom
P1629 code Theft Deterrent crank signal malfunction is the code that comes up on my 1997 Skylark Buick custom twin cam 2.4 L 4 door sadan. The car starts then the injectors shut off right after it starts and it stalls. Question if I change the crank sensor will that fix it?
