Bad starter or bad battery for Buick lacrosse?

Asked by Jan 16, 2017 at 01:28 PM about the 2007 Buick LaCrosse CXS FWD

Question type: Maintenance & Repair

My car won't start and I'm not sure if it's the battery
or starter. When I pumped gas the past couple of
times it wouldn't start right away it would make a
humming noise for a while then start up. This
would only happen when I would pump gas. I tried
turning my car on and now it won't start but when I
turned the key everything in the car would turn on
on its own(whipers, radio, heater/AC and then the
car alarm sound would go off too). I tried jump
starting it too and it wouldn't work. Also when this
happened the ABS, traction light and engine light
turned on. Any help would be great.

pumping the gas on fuel injectected cars does nothing. I would guess fuel pump.....you need about 40 psi or more for fuel injection, if the pump is weak you are not getting enough gas to start the car. You can borrow a fuel pressure tester from AutoZone and other auto parts stores
