If I have CEL fuel/air Code 25 and 26 and my car wont stay running does this mean the fuel pump is faulty? I cant hear the pump because I dont know where to find it on the gas tank inside the trunk. There is very minimal pressure through the gas lines and the fuel filter itself. I double checked bypassing my Fuel Pump ecu crossing Fp and B+ and there was no difference in trying to start. At first my engine had an erratic idle and would not accelerate then immediately would not start and run at all. I have about 9 volts running to the gas tank when the ignition switch is "on". Out of commission!

It turns out that I had a faulty 02 sensor that needed replaced- this problem actually cut off my fuel supply. I found that the fuel pump is directly in the middle of the fuel tank visible only when you remove the back seat.
