okay heres my problem. i got a great deal on a 1999 chevy 2500 6.0l gas, the fuel lines rusted out. so i replaced them, and now it cranks and i can here the fuel pump kick on. but it doesnt push fuel to the rails. i know im getting spark. can someone get me a diagram of all the fuel lines so i can double check that their all going to the right place. does any one know whats going on?
