2004 2004 Oldsmobile Alero won't start has fuel pressure and Spark

SOURCE: our oldsmobile alero wont start seems like not getting fuel

If the security light is flashing when the key is on then it is the passport 2 anti-theft system. You need to turn the key to the on position (one away from cranking it over) and leave it until the light goes out. Then turn the key off, remove it, then try to restart it.

check the fuel pump fuse, and if ok look foe fuel pump relay and replace it

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.
