You are not looking for "current". You are looking for "voltage
". I'm assuming you are asking about the "connector" for the fuel pump at the rear of the car. You need to determine if you have 12 VOLTS on the pin for the gray wire in the portion of the connector attached to the body. Do not probe the harness side of the connector if it is disconnected from the body side connector.
You will only get 12 VOLTS on that pin under three conditions:
1 - the engine is running, OR
2 - you have 12 VOLTS connected to the fuel pump prime connectors, OR
3 - without anything connected to the prime connector, you measure the voltage within two seconds of turning the key to "run".
When you turn the key to run, the PCM turns on the pump, but if the engine does not start, it turns the pump off after two seconds, and waits until the engine starts to crank before it restarts the pump.
Next, you want to verify that you have a good ground to the part of the connector that is attached to the body. Set your meter to OHMS. Touch the black lead to a good chassis ground, and probe the pin in the body side of the connector for the black wire. Should measure close to 0 OHMS. If it reads "out of range" or a very large number of OHMS, the ground is faulty.
