How much should I expect to pay a repair shop to replace a fuel pump sensor in 2004 Cadillac in Charles City, Iowa

What is your question?

Our shop diagnosed or problem as a fuel pump sensor, but $300+ seems awful high to replace it when google said it was a pretty cheap fix.

What makes this problem better or worse?

nothing makes a difference, whether it sat awhile or has been driven

How long has your 2004 Cadillac DeVille had this problem?
