My 09 MDX was sitting for a week while I was away for vacation. My friend needed to borrow the car, and he got spare keys from a family member while driving it he told me he heard a loud noise, but didn't know if it was terrible since he drives a Honda Clarity. I attempted to start it, and it barely ran, and I heard the noise myself, I turned the engine off and the key to the on position and heard it coming near the gas tank. I have no check engine lights and no codes But for sure, its the fuel pump. Does anyone know an estimate for part and labor and possibly if I can do a DIY on it to save some cash.
