This usually occurs with more mature/fewer-common motor vehicles or In the event the manufacturer no more can make autos. And particular repairs don’t implement to each make & product.
As mentioned earlier, higher resistance within an electrical circuit reduces the amount of voltage downstream of The purpose of high resistance. Considerably less voltage towards the motor usually means the motor would make significantly less electric power. Merely examining for voltage Together with the fuel pump disconnected doesn't inform you if there is any resistance within the circuit since the resistance only will cause the voltage drop although the circuit is working.
This ordinarily transpires with more mature/much less-frequent automobiles or Should the maker no longer tends to make automobiles. And specified repairs don’t implement to every make & product.
