Is there a difference(between the two tip sensor and fuel cut offrelay)?How can you test a tip/angle sensor? Where and is there a fuel cut off sensor?I tried jumping the tip/angle sensor,I checked all my wires on the ECMor ECU they are tight,and my fuel pump still doesn`t come on when I turn the key.Do you think it`s my ECU or ECM(whatever you like to call it).I am at my wits end please help!!!!
