We installed main relay, fuel pump, pressure regulator, fuel filter. However, when the igniton key is in the on position, usually, it pressurizes the fuel pump.But even with the key on, sometimes the main relay doesn't send power to the fuel pump. I checked the fuel pump wires.... no power. Even while driving, the power cuts out and the main relay does not make contact to the fuel pump. Sometimes it makes connection, sometimes it doesn't. Do you have any ideas? Anybody? I spent the last 3 days working on it and haven't made any progress. This is my daughter's car and she really need it. It really sucks!
