98 Chevy Silverado

Asked by Mar 12, 2017 at 06:28 PM about the 1999 Chevrolet Silverado 1500

Question type: Maintenance & Repair

I have replaced the alternator twice,
battery, and fuel pump. If the fuel tank gets
below 1/3 of a tank it acts like it is out of
gas and continues to die. You can drive it
at a speady speed of 35 but if you go
under or over it will die. Also the battery is
not keeping charge again. We have to keep
jumping it

Sounds like you have multiple issues. The battery losing a charge means you have a parasitic draw on it. Something on your car is draining it. You need to test for what circuit is causing the issue. There are youtube videos on how to perform the tests or have your local mechanic help you out. The other issue is fuel. I would suspect the fuel pump, but you replaced that already. Check the fuel pressure when your at 1/3rd a tank. Did you change the fuel filter as well?
