Question about 1989 Oldsmobile Cutlass Ciera
Since you have already replaced the most common components that can cause a no spark condition I suspect a cam sensor error or crank and cam sensor going out of range with eachother.
This may or may not cause a check engine light on this year vehicle. If the cam sensor is working but the timing chain is severly worn (which on an 1989 which could have high mileage is entirely possible) the crank and cam sensor will get out of wack. The ECM (computer) will shut down but will not throw a code in this condition. Later model years corrected this lack of error code. Chryslers of the same year had the same issue.
I have seen many mechanics throw a lot of parts at these trying to solve this issue. Many times the vehicle will start right back up other times you have to let it sit. Without a lot of testing I cannot be sure of this, but it's worth looking into before you spend a lot of money replacing good parts. I have also seen vehicles with this problem break the timing chain prior to getting properly diagnosed and then you will be out a lot more money.
