I have a Trailblazer 302 I l got new around 2008 or so. Low hours on it. Not getting any gas past the fuel pump. It will pull gas up to the filter (new) I checked the little electric gas shut off and it is working. The fuel pump is very new. I will get a new fuel pump tomorrow after work. Is there anything that could go wrong with the fuel pick up in the tank? I did have to let it set for about 4 months when broke my ankle.
