What's the cost of changing the fuel pump on a 2005 Chevy Trailblazer?

My fuel gauge doesn%26#039;t work and my car is making a humming noise. The check engine light came on today and everyone is telling me it is the fuel pump. I live in Chicago. Any good and cheap mechanics in the area/?|||Before you do anything, take your TrailBlazer to a reputable mom-and-pop mechanic in the local area. Avoid the dealer unless the vehicle is still under warranty -- dealerships charge top dollar and do crappy work. You want to be 100% sure it%26#039;s the fuel pump before you invest any money in it, and it may be a number of other things (sounds like an electrical problem to me). If it is the fuel pump, you%26#039;re looking at around $400.00 for the fuel pump plus the labor to replace it. The TrailBlazer has an in-tank fuel pump, so be prepared to pay $600.00 to $800.00 for labor.|||You%26#039;re looking about 800-850 dollars.|||Your probably looking at about 2500 dollars.|||From what you said, most likely, it%26#039;s the fuel pump. Don%26#039;t replace any part unless it%26#039;s broken or wornout. You can test the fuel pump%26#039;s flow %26amp; psi at the fuel rail.Shops charge to empty %26amp; remove the gas to replace the pump.BUT There%26#039;s a really cool short cut that even the dealerships do. Cut a 3 sided, 6%26quot;x6%26quot; flap in the floor %26amp; peel the sheetmetal back.Change the pump, push the floor back %26amp; seal it. =^ )|||ITS 2 YEARS OLD . IF YOU HAVEN%26#039;T GONE OVER THE MILEAGE BRING IT BACK TO THE DEALER TO FIX IT. IT WOULD BE UNDER WARRANTY
