Default 07 500 EFI wont start

Does anyone know how much pressure the fuel system should have? I pulled the fuel line off right under the tank and turned the key on, it just kind of trickled a few ounces (if that) didn't seem to have much pressure. Also, the spark plug doesn't seem to be wet at all. It is getting spark.

Fuel pump pressure 39psi+_3

80% of all EFI problems are caused by wiring harness connections . Follow a common sense approach when disgnosing a potential EFI issue .

I know I am replying to an old thread. I have no fuel pump noises on prime. it sat for 3.5 years. on low fuel. can it be the pump?
