#4 of 52 Malibu Fuel Sensor and Fuel Pump
Mar 18, 2008 (6:47 am)
I have a 2003 Chevy Malibu with 76,000 miles. The fuel sensor needs to be replaced (as verified by a dealership test). The dealership cost is $540. (The high price is due to the labor involved in dropping the tank.) A local garage will replace the entire fuel pump for $500. They say GM pumps have a "gold" metal that gets eaten away by gasoline. They say a Carter pump is better, cheaper, and will last longer. My questions: Should I just replace the fuel sensor, since that's the only problem right now? Or should I replace the fuel pump while the tank is dropped, with the assumption that the pump is nearing the end of its life?

As a DIY I would just replace the sender. You are not doing the job so I would go with replace the pump. If it was my car I would put in another Delco pump. I can buy one for my truck for $228 and $12 for shipping.
I once had a sender replaced under warranty on a Chevy Cavalier, the wait was less than 1 hour.

Only 50000 miles, 2003. From what I have read in these forums and else where this is a common problem with this pump. Cost me $400 bucks to have a new pump put in. Of course they had to drop the tank, etc. Pump cost just under $300.
#7 of 52 multiple fuel pump replacements & manifold gaskets

2003 Malibu. Had to replace the fuel pump at 61,830 miles. Changed fuel filter 30,000 miles later. Car now has 110,000 miles and am told the fuel pump has failed again. Shouldn't fuel pumps last longer than this?
Also was told that the intake manifold gasket was leaking coolant on the front and back (external leak). After searching this forum, it looks like this might be a common problem. Is there more to come on the top & bottom?

After market pumps can be a problem, go with Delco.
Not sure your gasket question, but get them replaced.

A class action lawsuit is nearing settlement in CA for the intake problem. I believe that it covers 2003 models as well. I had mine done three times.
Look up Gibbs LLP in San Francisco.
Malibus are junk. GM does not stand behind their product and that is a shame. I have always bought GM and this was my last one.

Be sure you don't run the car with very little gasoline in the tank.

i'm a mechanic,and i found that IT IS A REPEAT PROBLEM w/ the intake gaskets. they are made of plastic. i just purchased a '99 malibu (3.1) for wife. the 2nd day i had it, it started leaking coolant from back of int/gasket. before i got it home,it started leaking INTO the engine.now i found that "fel-pro"makes a replacement kit,that is better(and more exp.too!) ,than factory. i put a set on mine, so far so-good. car only has 157xxxmls on it. you really must fix leak asap, or you will KILL the engine. good-luck; rick.
