?need info i was driving my Buick the other day.when she just shut off on me.she wont fire up just spins over the only changes i made prior to that was my turbo, i installed a commander chip and changed the oil.now she spins over easy like there are no spark plugs in it,i did a compression check all cylinders read 120 i believe it would read higher but my batteries weak from sitting i was thinking it might have jumped timing if any body has some info i would appreciate it.
