with factory fuel injection.. and electronic timing control... you have to disconnect the bypass wire or jump the A B terminals on the aldl connector under the dash.. this locks the timing so you can use a timing light to set it..
setting the timing is described usually on the little white emissions sticker on the fan shroud... what you have to disconnect or jump to set it that is..
pull the cap and rotor if you are still having problems.. take a bright flashlight.. look straight down the shaft.. see if the tiny bit of exposed ring shaped magnet is cracked.. it will be the second layer in the reluctor..... when it cracks.. it makes for all kind of weird problems...
