My fuel pump in my 1990 Olds cutlass Cierra S does not pump any fuel. There is no power to the relay when the ignition key is on. What do I check next? Mike

then check this wire from the relay to the pcm to see if there is a break in the wire or bad connection. if not then the pcm needs replacing. also check grounds for this circuit.
You'll have to figure out if it is a fuel or ignition problem. Is the check engine light on ? Have you checked for trouble codes ? It could be a relay, the ignition module, coil, fuel pump, or a list of other things.
their is no reset button for the fuel pump on a 1990 olds. their is a relay located under the hood though but these rarely go bad.. might be worth a shot though
the most common problem next is the crank sensor. use a heat light to warm up the sensor to see if it is that. by using a heat light you can narrow down what part has the temperature glitch. Don't forget to try the engine computer.
i was just dealing with the same problem check out your fuel injectors , fuel pump, ingnition module with coil overs and possible fuel filter mine was the pump injectors and module its also a 93 cutlass ciera 3.3 fuel inj. hope this helps
