2006 Chevrolet TrailBlazer LT 4dr SUV 4WD (4.2L 6cyl 4A)
i bought this truck after i totaled my ford escape..i love it at first..8 months later...well car just shuts off for no reason,thought it was the battery but it's not.we got stranded at a mall had someone try to give us a jump and nothing,so called roadside asst and then the truck just turns on before tow arrived.and now the ac is not working at all.not to mention the inside it CHEAP CHEAO CHEAP oh did i mention, CHEAP! no one know whats wrong with it
so it's just sitting in my driveway.after looking up the issue i found hundreds of complaints with the same issues..please stay away..
my girlfriend has one and i've been repairing it for the 2 years that we've been together.
i had the same problem you described took me a while to figure it out.
it ended up being the brain box it wasnt sending a signal to the fuel pump and only the fuel pump since it was working for every thing else i just jumped a hot wire from the ignition to the pump so it would turn on and off with the vehicle and works fine for that problem anyway. cant say much for the rest of the vehicle
