I need help I have an 87 with the in tank fuel pump. I reciently dropped the gas tank to add the ORD 1" body lift. My problem is now the truck wont start. it ran great when i parked it. it starts when i pour fuel into the intake but it seem no fuel is gettin up to the injectors. Several years ago CHevy installed a new fuel pump and cut the wires to the pump, stupid me, when i dropped the tank i didn't mark whick ones go to whick. and now i think that is my problem. any ideas. their seems to be a pink and grey wire coming from the truck and a red and whit comming from the tank. i figured the red go together and the whites/grey goes together but no. i also tried it the other way with no luck. the pump usedto run whenever i turn the key but now nothing DOES ANYBODY HAVE ANY IDEAS ON HOW TO TEST THE PUMP AND OR REWIRE IT TO WORK? Whats wrong with big and wide?
