same exact problem with my car today! what was the problem with your car? im going to take my car into a shop today, but if you could tell me what happened to your Chevy that would be great. i don't want to get ripped off.
your quote: "I have a 05 Malibu LS 3.5L V6. I have been having a issue with my fuel guage. If i fill up my car the gauge will drop to empty. Once i drive and burn some of the gas out it will read full until i get below half a tank. If i sit idle more than a few seconds it will drop to empty. i have only noticed it sputtering one time while idle. any suggestions other than a new fuel pump?"
#49 of 52 2005 Malibu problem, suspect fuel pump?
Jul 06, 2012 (6:34 am)
I have 240,000 miles on my Malibu, and up to now, have had great luck with it. Last summer, on a 100+ temp summer day, I was driving interstate and got to a traffic jam, everyone stopped. As I was sitting there for about 5 minutes, my engine started sputtering, the tach dropped and the engine died. I restarted it without much problem, but got scared and turned around and drove another route home without problem.
Hadn't had this problem again until now. Now, it is doing it after the car warms up, and when I pull up to a stop light, or even while I am driving down the road around 35 mph. It sputters, power drops, and then dies. I can get it started after a few sputters, and then drive it short distance, and then it does it again.
Anyone experience similar problems? My mechanic checked the engine but it hadn't thrown any codes and the engine light hadn't come on when it was doing this!

Did you ever get an asnwer on this issue? I am having the same problem. Mine only shuts off when I turn on the air conditioner and slow down. If I am on the freeway and going at a good speed I can have the a/c on but if I slow down the car with start to sputter and then die if I don't shut off the a/c quickly.

2005 malibu maxx 3.5. stalls when it warms up. changed EGR and cleaned the throttle body. i am trying to locate the fuel pressure regulator, but it doesn't seem to have one. there is nothing near the fuel rail and no vacuum coming off the intake. anybody have any ideas??????

The fuel pressure regulator is contained in the fuel pump module near the fuel pump outlet. The fuel pressure regulator is a diaphragm relief valve. The diaphragm has fuel pressure on one side and regulator spring pressure on the other side. The fuel pressure regulator is not vacuum biased. Fuel pressure is controlled by a pressure balance across the regulator. The fuel system pressure is constant.
