Question about 1998 Chevrolet Malibu

1 Answer

98 malibu possibly altinator problems?

I have a 98 Malibu and when I start it, after about 10-20 seconds, something kicks in under the hood and all the lights in the dash get brighter. I am not sure that this is a problem, but also sometimes when I pull up to a stop sign my car sputters like it's about to die and when the thing under the hood kicks in when I had my Fosgate 1200 watt amp in the trunk, it would cause the amp to stop working and start smoking. My check engine has also been on for a wile too. The power surge happens regardless if the amp is plugged in or not, if I have been driving all day or not in a month, or if it is hot or cold outside. Any suggestions or ideas?

It sounds like you have a Bad Belt Tensioner. If the Belt Tensioner is not Holding the Belt Tight Enough, it will not allow the Alternator to Charge the Battery Completely and will cause the Problems Listed Above.You will need to Locate the Belt Tensioner. It has a Large Pulley on a Bracket that Has a Bolt in the Middle and a Smaller Pulley that Goes Under the Belt and Holds Tension on it. You will need to get a Wratchet, Socket, and Cheater Bar. Turn the Bolt On the Top Large Pulley with the Wratchet and Cheater Bar. This will Lower the Smaller Pulley So that you will be Able to Remove the Belt. Then Remove the Tensioner and the Bracket if Required and Replace. Please Rate My Response! Thanks!

3.5l V6 Auto. Why is there no power at the fuel pump?


Just answered a similar question. Does it turn over? Either way, I would look for blown fuse and then check (usually) under the hood for a relay. You can some times test by taking another relay for lights or something not needed to run and switch them IF THEY ARE EXACTLY the same. If the pu,p works you will know.

Does a 2000 chevy malibu have a fuel reset button and where? it just died while at a stop sign, so we thought it was out of gas. we put gas in and it still will not start.


Hello mellissa, the 2000 malibu does not have a fuel reset switch. Check the fuel pump relay in the fuse box under the hood. Check for fuel pressure. You should be able to hear the fuel pump come on for a few seconds when you turn the key to the run position....Your fuel pump might have failed.
I hope this helps.

My 98 Chevy Malibu v6 3.1 liter engine high idling


You probably have a large vacuum leak. With the engine running, listen under the hood for a hissing sound. Check all of the rubber lines running from the intake.

Cheak your fuse under the drivers side under the hood. Look in your manuel for fuel fuse. It looks like a little black box.

1997 chevy malibu stopped while driving on highway, no sounds, no warnings, just quit. Anyone has a similar problem. Car will not start anymore, attemps to, but just sputters.


I had the same problem with my 2002 Cheavy Malibu. First check the fuses under the drivers side under the hood. Look in your manuel to find the location for the fuel fuse location. If that doesnt work then look at your fuel filter.

Where is fuse in fuse box on chevy malibu 2004


There are 2 fuse panels in car, 1 under hood and the second under drivers side of dash, above hood release area. Radio fuse should be under dash, most likely a blue(15amp) fuse. The fuse panel glossery should be on inside cover of fuse panel or in owners manual under fuses in glossery.
