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: Where is the fuel pressure regulator on a 2003 oldsmobile alero?

There are 2 fuel lines connecting to the fuel injector rail. The larger line is the pressure line and the smaller line is the return line. The smaller line attaches to the fuel pressure regulator. You will notice that the regulator also has a vacuum line attached to it. If you are planning on changing it your self, let me know. There is a specific way to change it for safety reasons.
Let me know.

SOURCE: need to change fuel filter on 1986 cutlass supreme

You'll find it in the carburator. Unhook the fuel feed line from the front of the carb and undo the large nut directly where the fuel line connects to. The filter is there.Pay attention to how the filter comes out and put the new one back in the same way. Hope this helps.

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.

1989, Cutlass Supreme, 3.1, what is the recomended fuel pressure? Is there a test for the fuel pressure regulator?

30-40psi. one thing to check first is the vaccumm hose at the fuel pressure regulator, take it off, if it leaks fuel, replace the regulator. when the engine is running you should have approx 30psi, with vaccumm hose off, approx 40psi.

Why is oil in the breather hose?

Thats not oil more than likely its fuel and that would mean that the diaphram in the fuel pressure regulator is leaking.Pull the vacuum hose off the regulator and look for fuel if any runs out of it then replace the fuel pressure regulator.If regulator is leaking it will usally cause the engine idle high.
