Question about 1989 Oldsmobile Ninety Eight
Probably timing. Aim a timing light at your crankshaft, and see if the mark is jumping back and forth irradically. It should be staying in one spot. If it's jumping around, your timing chain has jumped a cog.
If not the timing, then it's probably bad wires or improper firing order .

If you suspect its a fuel problem best to do a fuel pressure test, you can rent a tester at auto zone and do it yourself. They also can show you how to use it and what pressure it should be. Also if you turn the key to on position you should hear a hum from the gas tank and then a click that is the pump running and the click is the relay, if you don't then the pump isent running, also chk. the fuse and relay, it could be as simple as a blowen fuse or a bad relay.
