2000 malibu 3.1 wont crank...no fuel getting to motor, changed pump, ign switch,filter,crank sensor & fuel regulator.... the pump is prming i have spark & when sprayin fuel into throttle iit runs until it burns the fuel....please help

check if you have vapor lock in your fuel lines or a broken line if fuel leaves the pump but does not reach the motor it could be in the lines or fuel injectors. get a fuel pressure tester and check the readings

You can check for voltage and ground at the pump connector, engine cranking. Gray wire is voltage, black is ground. Check for an injector pulse, use a noid lite. If computer doesn't see an rpm signal, no injector pulse.
