Why wont it stay running when I press on the gas pedal?

Asked by Cheryl Mar 01, 2020 at 09:10 PM about the 2003 Chevrolet Blazer LS 4-Door RWD

Question type: Maintenance & Repair

Someone put muddy water into my gas
tank, I have replaced the fuel pump,
fuel filter, spark plugs and wires. It still
wasn't starting. So I pulled off the
mass air flow sensor, and oxygen
sensor. And it will sit and idle. But
when I press the gas, it shuts off.

When the mass air flow sensor is out and the oxygen sensor is out (disconnected) it will idle

No I didn't. However I did find out that I burnt the inside of the fuel pump again. So now another fuel pump will be going in today.
