Help, fuel to, not out of injection pump.

[Nessmuk]

Tons of fuel supply going to the injection pump. Only a trickle out at the injectors.
Got power to the fuel solenoid.
Tried tapping on the pump just in case.
Crack the injection line on the driver's front line, only a trickle of fuel.
Fuel is returning to the tank.
Something wrong between my spin on filter and the injection pump, or in the pump. It's a new last year pump.

A little info about year make and model and any mods done might help scare up some help.

Add to that....

Are you having a problem? If so, what?

The fuel events you describe sound normal. Fuel flow at the injectors is only a "trickle", at best. If they weep any fuel while cranking, the pump is sending fuel. If all is as it should be and it doesn't fire or run well, confirm you are actually sending the correct fuel to the cylinders (as in, not gasoline).
