Vortech Boost A Pump Priming problem
- Thread starter Jukens

He shouldnt need to replace the fuel pump fuse under the hood if hes using the vortech bap. it has its own dedicated power feed from what i gather in the instructions.
in theory this is true but I have seen cars pop the 20amp and when swapped to the 30amp, they are good.
it's showing correct voltage correct? 12volts in, 17volts out? The picture you have posted is the correct wire too and i'm sure the ground is good. You didn't do anything with the small wire right?
Yes correct volts just like the last bap. The programmable one only has 1 small wire which is the signal source to turn on (red wire in above picture) other than that I have the output(orange wire in above pic), main power from battery fuse box, and a ground. Picking up a new fpcm from ford tomorrow to rule that out.
Where did you hook the main power line too in the engine bay?
You don't need the small one for anything. Just the in and out with ground. Can you take a picture of everything? thanks
This is how I have it wired, it requires you to use the small gauge wire to the stock harness, its the trigger wire.

oh, okay. I see now. This isn't the universal BAP. I was explaining most towards that. What we use and have had no issues. Now it makes sense why your using that
Is there a chance that the vacuum line running from under the hood to the boost a pump in the back of the car, is pinched somewhere? Would that even effect it? Has vortech been able to offer any assistance? This sounds like a problem with the boost a pump or it's install and not the car. I would think vortech could walk you through troubleshooting this thing.

Tried vortech only response was they never had this problem and their bap shouldn't affect prime. They sent me a new one and its doing the same thing. The boost reference does nothing until it starts seeing boost. I replaced the fuel pump control module and it made no difference. Starting to feel like there is an issue with my car.
If your car doesnt have a problem when you remove the boost a pump, than its not your car. It has to have something to do with the install or possibly a complete bad run of boost a pumps from vortech.
Maybe my PCM or pump is acting up on the initial prime since its seeing 13.5+ volts with the bap which is more than the stock harness sends (12.5v) before starting the car. Anyone had a stock pump take a shit on them yet?
The increased voltage shouldn't effect priming. I have the universal pump that produces a constant 18v. When I prime my car, you can hear the fuel pump significantly louder then when it was stock.
No, your pump is fine. I installed a KB BAP on mine today, very easy on that model. Cut a wire, splice two BAP wires in, ground the BAP. Primes every time.
I wonder if the unit you're using has a delayed powerup? The PCM fires the pump up for two seconds when the key turns, as I explained to you in another forum. I would pull the FPDM connector off, put a voltmeter to the main FPDM power circuit and have someone turn the key. If power doesn't come on instantly, there's your problem.
