Trying to figure out why engine wont start after replacing fuel tank, pump and filter. Have disassembled TBI and determined injectors are clicking using a 9 volt battery. Have fuel pressure to TBI. Will start when I pour gasoline into venturi. I know the truck well as I bought it new in 1988. Was running fine until it decided to not run anymore. After setting for a while (months) I decided to do repairs, i.e., replace items mentioned above. Engine turns over normal. Looking for help in getting Ole Blue running again.
