how do you replace the timing chain in a 1999 buick century with the 3100 motor? The diagnostic tester said the oxygen sensors were bad so i replaced them and the car still wont start up and its got spark and good fuel pressure.the car ran fine good than it just shut off while driving it cranks but wont run an i checked everything else so it must be the timing chain rite?

    Changing the timing chain can be done in an afternoon but it is a big job. You'll need to remove the alt. power sterring pump and anything else that would restrict the removal of the timing chain cover. the crankshft pulley most also be removed.

    Before getting into the timing chain it may be a crank angle sensor problem. I would start there first.
