Here is a short history car has been sitting for 3 years with old gas and moisture in the interior after cleaning her up removing sending unit replacing fuel pump and in line filter fresh gas. when i try to start it turns over no problem but will not run . i hear nothing in the fuel tank that would tell me fuel pump is cycling i pinned the 4 prong plug and get no sign of power anywhere turning key on and off ,i am pretty sure i should be able to hear the pump run for a few seconds yes ?..i am trying to figure out why i have no power to fuel pump and wondering if security system or ecu maybe a fuel relay ( not sure where to find relay ) .i have read some threads talking about ohm testing and a few other checks i could use a little schooling on this any help would be appreciated a place to start would be good thanks :confused
