2003 Oldsmobile Alero 6 cyl Two Wheel Drive Automatic

It has spark, compression, Pull the injector rail to check if injectors spraying have power to every connector wires. All 6s injectors are not spraying, but fuel pressure regulator leaking when cranking engine to see if injectors are spraying or not do I have fuel pressure regulator problem. Or is their a problem that I have missed. Replaced fuel pump twice, fuel filter, fuses relay ok

Hi kamaka, Welcome to 2carpros and TY for the donation

If the fuel pressure regulator is leaking it will flood the engine, if you use a noid lite to check the injectors and its not flashing there's a problem in the computer injector driver circuit

Noid lite flashing the driver circuit is doing its job-if the injector is not spraying fuel in a cone shape pattern its defective-You can try cleaning it and see what happens.
