Fuel Issue After ZZP BRFPS Install...

[edubs]

So, in an effort to just get one of the many things I intend to do mostly off my plate today, I decided to install the ZZP Boost Reference Fuel Pressure System on my car w/o a vacuum reference so it was bypassing that particular regulator, but ready to connect to vacuum once I got my hands on HPT.

Whelp, turn the key to accessory, and it sounds like the pump is working extra hard, but figured the extra noise was just the pump filling up empty space and paid no attention. Turned the key to ignition and it starts, maintains idle for a second and then starts bouncing 1K and 1,250 rpms. It'll do this for a while and then stall out.

So, needless to say, I reverse install. Note, when uninstalling, I start the car and pull fuse pump like I always do and attempt a start or two to try and flush the lines. Well, this time when I disconnect the lines, there is significant pressure and fuel still in the lines, basically, like there was a restriction in the system. I figure the FPR is set way off and that was what effected my idle. Reconnect stock setup, start it up and the freaking thing is still having the idle issue. I am by no means a fuel system expert, but I am guessing that either my stock regulator or pump are now messed.

Things to note:

I do not have HPT to log anything at the moment.
The car is still in SD mode cause that's where I left off w/ tuning.
Pump has louder wine than normal.

Any ideas or similar experiences. Battery has been disconnected to reset, even though I'm in SD...

had this same issue on an install. fuel pressure would skyrocket to 120psi. there was blockage in the fuel filter that went through the return fuel line and was causing the restriction. after a couple times of dropping the tank to diagnose we took an air hose to the return line. this little filter screen and a chunk of something came flying out. did you happen to reuse your fuel filter?

I have yet to see any of these deals work, the kennebell ones , you name it... so u r not alone...lol but I am not sure that running in SD is a good idea

What year is your car?

Did you remove the little screen that's inside the stock regulator area? What is more than likely happening, is you have a blockage and the fuel pressure is sky rocketing. Happened with Danew's... just needed to remove the screen. Joshua (Blazin) or Duncan (TTMR) can probably explain it more thoroughly that I.

The ZZP BRFPS works... you're just changing fuel regulators. They're no trick to it, in all reality.

Thanks guys. Fuel filter was changed at 30K and the car has 36K, so I didn't see a need to change the filter. Car is a 2006 and I did not remove the screen filter. Car has 3/4 tank, this is going to be a blast to drop the tank, lol...

Thanks a lot for the input!

no problem. we dropped the tank 6 times that day. the last time we dropped it in 6 minutes :guns: we even skipped on dinner trying to figure the sh!t out

[edubs]

Any hints or tips? I'm not retarded, but I have never dropped the tank, if ya know what I mean...

Helps to have a buddy... use a jack, multiple jack stands, and lots of patience if doing it alone.

undo the big nut from the fuel rail and stick it in a gas tank, use a jumper wire in the fuse box to turn the pump on. pump at least 5 gallons out of it. the weight will be manageable past that point. undo all the quick disconnects, fuel fill line with a flat head, and the brackets holding the tank up on the front side of the car and the tank comes down. be careful with the plastic fuel lines. they can be very easy to break

them chicken sandwiches were good

Yeah, they were.

hmm mine has been stalling on me on occasion but I think it's more the tune than the brfps. I was running the brfps on pump gas with no problems and then when I made the switch to E85 is when I started having trouble. I changed the fuel filter today and so far so good but i'm still scared to leave town with my car lol

[edubs]

Dropped the tank but I'm not quite sure what screen you guys are referring to. I'm also curious where you disconnected the return line to blow it out. I don't want to just start yanking on stuff and breaking something, ya know?

[ndbalt07]

the screens on the fuel pump i would assume. you have to take the fuel pump out and take the canister apart and they are at the bottom of the canister.
