Hi everyone, I need help. I recently had to replace my fuel injectors on my 1998 Chevy Astro. I replaced all six. When I start my van up it ran for a few seconds and it stopped. Upon much time investigating, I noticed that cylinders 5 and 6 kepted flooding with fuel. When I shut the key ignition off the fuel pump will pump fuel to those to cylinders. Enough that it would run out the side of the engine when I took the spark plugs off. Any one have any ideas?

:confused:
