2002 Oldsmobile Alero - will not start
Have already changed fuel pump.
The car ran for appx. one day
Currently the fuel pump relay # 18 is turning on for 2 seconds when the key is turned to the ON position. This gives me 12 volts continuous back across the pump motor on the other side of the connector that goes up to the fuel pump. I have ohmed out the pump motor and it is the same resistance as the pump. The motor that I pulled which, if I feed 12 volts to, runs (old fuel pump motor). So, I do not believe that the old fuel pump motor was defective.
I hooked 12 volts directly across the fuel pump motor (new) and I cannot hear it running - black being the ground, gray being the 12 volt line
I have spark and no security light is on, no codes are displayed
Question - is there anything that might make the pump not to turn on when fed 12 volts --- (? Is there a pressure switch on the pump that it might pressure up when I turned on 12 volts, causing it to NOT turn on?).
I have also added a new fuel filter with the new pump (new, not rebuilt, pump)
I do not hear the new fuel pump coming on when I put 12 volts across it.
