so for saftey purposes i have to recomend gloves and saftey glasses durring this operation,aproach the engine bay and locate the battery casing. many vehicles encase the battery with a "saftey"plastic sheild which is easily removed,along with the saftey bar that secures the battery to the frame. then disconect the negative, then positive termanals. remove the battery and make sure not to rub up against it or get the corrisive materials on your clothing or skin.

Aveo 80,000 miles 2009. Acts like it doesn't get fuel. Jerks, and dies. Keeps this up, and then maybe takes ooff real fast. Especially when it is warm out.


Well that's where doing some testing comes into play . Instead of asking on here an expecting a magical fix , learn how to test an lean about the different systems on your vehicle . Test the fuel system , fuel pump pressure an flow , testing electrical circuits with a DVOM - digital volt ohm meter . Eliminate thing's that are right . Find service information manual so you know what the fuel pressure is suppose to be , how much current the fuel pump is expected to draw . Also the electronic ignition system specification. I think it's cool you want to find out about you vehicle , but go to school an learn about it the right way . Because listening to someone guess will get you no where . Your vehicle is a rolling computer , has a lot of electronics . Electric Testing Techniques You Need to Know Motor Age TST New Battery Starting Charging System Testing Techniques
Fuel System Diagnosis Presented by Delphi

If you don't understand any of this , do yourself a favor an take it to a qualified repair shop . Repair modern automobiles isn't easy , even for seasoned Technicians .

Well, don't get nervous. Having to play with the switch and having eventually close the window is a good thing. Go to the aoto psrts store and pick up some silicone spray lubricant.Open the sunroof and spay everything you can see. AAny Tracks, guides. etc. close the window so its only about 3/4 shut and spray yje newly expose tracks and whatever else that has come into view. See how that does asyou run the window through several open and close cycles. Those sunroof motors sre not very powerful and the least bit of resistance works them hard. Good Luck -Ned_
