Fuel pump help please.

dP3NGU1N

Fuel pump isn't activated on ACC, it will prime on ON position for a few seconds and then stop. I would check for power during that time.

Any other variables? I'm not familiar with a power booster but if the stock wiring was too small a gauge to run the pump before I don't see how keeping the stock line is going to allow it to run after. Also, check your grounds if you needed to add any for the booster - recently had a whole ordeal where a faulty ground was my culprit.

Ok from what you said:
-You have no power coming from the wires that are supposed to supply power.
-You made sure your multi-meter was on a good ground source to give you an accurate reading.
-Main fuel pump fuse is good.

Questions:
-Is there another fuse supplied by BP kit?

My next steps would be:
-Make sure fuel pump relay is good
-Make sure there's no opens (breaks) in the wiring that was installed there by doing a continuity test from source to fuel pump (make sure to isolate the wiring)
-Make sure the ground wire is good. No ground = not a complete circuit for amperage to travel.

Good luck! Definitely try and contact BP.

I asked this right!?

lol, Glad you found it. Now find a short to ground which increased the amount of amperage past what the fuse can handle.

Check that power wire through and through to any rough edges in your cars body.

Good Luck!
