i installed a walbro pump in my 08 hhr i just plug it up. i can hear it but no gas to the fuel rail.any idea

 

Is it hooked up backwords?

 

not sure we just pluged it in . im thinking the wires need to be change around .is that what you are asking me ?

 

Yeah, if the leads are backwards you'll hear it run but get no pressure, also possible that a hose in the tank came loose, I've had that happen, installed a fuel pump assembly and the feed line in the tank came off the pump in the tank after I sealed it all up.
