My 2002 s-10 zr2 4.3L has had alot of fuel pump issues, I recently installed a new pump, fuel filter and fuel pressure regulator and the truck still wont start, however it does chug and backfire, witch makes me think it might be an ignition or timing problem, but the only code I have is an evap emission control malfunction. I know quite a bit about vehicals but im stumped on this one. Any ideas?
