Well the fuel pump in the gas tank provides fuel pressure.
Have you checked it with a gauge at the fuel injector rail ?

Check for fuses/power/ground to the engine computer (or injector drive computer) whatever the case is.

Spark, fuel pump, and starter all are independant of the fuel injection computer.

Either the computer itself has gone bad, or it is not receiving power or ground, or wiring to the injectors might be bad...

SOURCE: 1996 Oldsmobile Cutlass will not stay running

Your fuel pressure should be at least 40psi at all times. The most common problem is the diaphram inside the "fuel pressure regulator" fails. This in turn sends excess fuel into the vacuum line and intake. I would replace the fuel pressure regulator.

I hope this information helps you, and I wish you luck with your repair.

Why do my 95 oldsmobile cutlass supreme dies when hit gas


Did you replace the fuel filter as well as the oil filter ?. If there is a good spark at the plugs it has to be a fuel problem . Check the fuel pressure and flow the flow is most important. if the pressure is high the regulator on the fuel rail may be stuck shut . and there will be no flow on the return line.

Is there a fuel reset switch in a 1990 Oldsmobile cutlass supreme


No GM doesn't use a reset switch (really called a "Inertia fuel pump cutoff switch"). The fuel pump is cut off by an oil pressure sensor. If this car has the original pump you likely just need to drop the fuel tank and replace the fuel pump. Does it start if you spray starting fluid into the engine air intake?
