hpfp

2008 speed 3. Bnr s3, jbr 3.5" intake, hks bov, front mount intercooler, auto tech hpfp internals, ngk 3787 plugs, brand new itfp. Hpfp pressure dropping at wot only 1 cell. Being tuned by Justin at freektune he suggested new plugs. Didn't help. I replaced itfp and filter, didn't help. Hpfp has...

Found some hpfp internals for 140$ wondering if I should pull the gun and buy but I’m having some doubts because I noticed some slight scratches on the shaft. Lmk

3/29/2023 Update: CorkSport internals were seizing. Installed AutoTech internals and the car runs normally again. 4/21/2023 Update: CorkSport confirmed the internals were bad after testing them at their lab, however were unable to warranty them since I had a shop purchase and install these on...

Hey guys, I have a question for you. I have a 2007 Mazdaspeed 3 that had a motor that pistons hit the valves. This is what I have done. First of all I purchased a motor from a salvage yard gen2, put it in and in less tha 300kms piston 1 suffered a cracked piston. So down 3k on a engine. Still...

I have an 08 Mazda S3 that was brought to me by a friend of a friend. The story is old engine went and they paid a shop to put a be one. Now it’s been running ruff ever since with a strong gas smell/rich smell. It was later taken to a reputable tuner who smoke tested it replaced a bov that was...

Ok guys. Odd thing, car runs and drive somewhat with hpfp unplugged and runs very rich with the black smoke and all that shat.. Plug it in and car wants to bog down and die and most of the time won't start. I have swapped the hpfp out twice. Same result out of both. Pulling a cel for intake...

This might help those who anyone who's experiencing fueling issues and reading 0psi of HPFP fuel pressure, or those who swapped in a JDM motor to replace their stock one like I did. TLDR: Bosch 0261545038 is the sensor you need, use a 27mm deep well socket to remove/install. The stock motor on...

Update 3/1/2022: This issue has been resolved. Spill valve was responsible for 60psi drops and PRV was responsible for for fuel pressure never exceeding ~1700psi. Year/Make/Model: 2008 Mazdaspeed3 Mileage: 160K chassis / <1K motor Location: AZ Concern: Fuel pressure drops to in-tank pump...

Hey everyone, I'm looking to get some help on identifying the HPFP internals that I currently have in the car, as the previous owner bought the car with them installed and the previous previous owner said he never had Autotech, only CorkSport. Since I know these are not the latest CorkSport...

Hello guys, this is my first post and also my first Mazdaspeed 3, I got a problem and i'm out of ideas; my HPFP is not running, I can't hear it, I checked the voltage from the connector to ECU and it reads 8 volts. My car is just running with the fuel pressure from the pump in tank. I connected...

Hey all, I'm new to the site so sorry if this has been asked before. ( i searched and couldn't find anything.) My 2009 Mazdaspeed 3 is having issues with randomly cutting or losing hpfp pressure, and crazy FT. I randomly get P2178/P2188 at least once a day. My fuel trims will go anywhere from...

Car: 2008 Speed3; 3.5" intake, CS turbo back, AT internals, Reyes Wiretuck, AP v3, (Same tune for years), Damond PCV plate with dual CCs. 180 compression all cylinders, last checked 07/10/2020. Issue: KOEO fuel pressure won't go above 36psi. HPFP pressure won't go above 1060psi after the car is...

Alright guys I'm super new here actually first time on posting in a forum lol. So I've been having an intermittent super rich condition usually when turning in 2nd gear my afrs are around 8.6 to 9.2 and my fuel pressure is around 1700 to 1800. I replace the wiring harness and that worked for 2...

A long time ago in a shop not to far away from CorkSport's current location (we moved, lol) we introduced our Mazdaspeed 3 and Mazdaspeed 6 high pressure fuel pump internals kit. We went with a 9.8mm piston size, included the OEM style of spring keeper, include an upgraded pump spring, and...

I've come here as a last resort. Heartbroken over months of trial and error. Recently had the engine replaced, and had put in an Autotech HPFP. She has an HPS CAI and a HKS BOV... I know, it's horrible for the engine, but it came with it when I bought it, and I spent all my resources in...

EDIT: Problem solved, both my HPFP housings were bad. New HPFP housing solved the problem. More detailed explanation in a response posted below. Hey everyone, been pulling my hair on this one. Here's the scenario. Car is running fine (2011 speed3), for 1.5 years. I buy brand new Corksport HPFP...

I recently rebuilt my HPFP and instead of putting it all in my engine thread I figured I would make a dedicated post. UPDATE: Corksport now sells a kit for this as well. They are pretty much the same thing so whatever you can get, get that one. and their GUIDE This is actually pretty simple...

I'm not going to be modding my speed3 until it is paid off (trying to pay off a 5 year loan in 2.5 years). I think my fuel pump is bad, as occasionally it'll take longer to start, and just sit there and crank and crank on until I start hitting the gas. Would you recommend going ahead with a HPFP...

Hello Everyone, ive done the research that i can to find a solution to my problem but the only two threads that had the same problem as me never updated with a solution. I was running a 3rd gear pull while data logging because of a fuel cut i was getting. As you can see my fuel pressure is now...
