When my 2006 Pontiac Montana SV6's fuel gauge gets to about a quarter or a little less of a tank the van dies and will not start until 3 gallons of gas is put in the tank. Then it will start right up. It runs fine as long as you have more than a quarter of a tank. what could cause this. If you fill the tank up after this happens it will only let you put in about three quarters of a tank of gas. This lead me to believe that some trash, water, ect is in the tank. What else could cause this?

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

no that is only the older rear calipers on gm and others. the fronts do not have that style caliper and sound like the calipers are frozen and may be way your changing the pads. try opening the bleeder screw and then compressing them if they go then you need need brake hoses and if not you need calipers. god luck man
