If fuel program strain fulfills specs at idle, lots of techs will think every thing is Alright and appear no additional.

As observed earlier, superior resistance within an electrical circuit minimizes the quantity of voltage downstream of the point of large resistance.

Using the voltmeter’s good probe connected to the battery by way of a lengthy jumper wire, use the damaging probe to again-probe the fuel pump connector even though the pump is functioning. If there is totally no resistance into the movement of current between the battery and that connector, there will be no change in electrical strain, no lack of voltage in that circuit, and the voltmeter will exhibit zero volts.
