Ok, we are on the right path. I'm going to make you test your fuel pump without expensive equipements.
(a little taste from my future book) title is :"MECHANIC EASY"
you are going to test your fuel pump using the headlights on your car, a long jumper lead and your battery.
1)test the ground of the pump.
Connect a side of the headlight the the jumper lead and the other side of the jumper lead to the battery.
The other side of the headlight connect to the fuel pump ground wire, this usually for a darker color.
* the headlight should light up brightly. This will demonstrate that the fuel pump ground circuit can at least deliver 4 to 6 amps of current.
If the headlight is not bright, you have a bad ground.
If the ground is good
check the power.
Connect the headlight to the negative side of the battery,
connect the other side of the headlight to the fuel pump positive wire( red).
Cranck the engine.
*the headlight should light up brightly.
If there is ground and power at the pump connector, replace the pump.
If the headlight is not bright, you have a disconnected power.
Let me know after you run the test.
Ask me if you need explanations.
