This might help some of you guys, especially those doing swaps. Thanks @gloverman

Hey Guys, I'm Making some Fuel Pump ECU replacements. It works with the standard Engine ECU and should be a direct replacement for the factory FPC. I have tested it with a UZZ31 ECU. It has the OEM connector, and is rated for at 20A. Version 1.0 is just On or Off, no two speed pump control...

Hi everyone, I have an enquiry that I hope you can help me with. Basically, do I need an AFPR or will the stock one be more than sufficient? I have an early 1UZ-FE and I am in the middle of fitting a Ford M112, along with 300cc injectors (up from 250cc), a water/methanol system and a Walbro...

Hi again guys, I have another problem with my UZZ31 if you could lend some advice. Here's the issue: (Updated). One day the car refused to fire. Cranks but won't fire. No fuel delivery. Swapping the main relay with the dimmer relay does nothing. Other fuses seem good in engine bay... Applying...

Hi ya'll, I've got a '97 sc400 that I swapped the engine from a 94 LS400. I swapped the engine to OBDII with the sensors/wire harness/cams etc. from the newer engine. After getting it together I could not start it. Upon closer examination, I found no spark, check engine light on the on position...

HI! I have a Japanese Toyota Soarer UZZ31 V8. I'm thinking a relay or fuse is out but have no idea where to start. If someone can provide a pic of the fuses/relays I should be concerned with I'd appreciate it. My car will not start. It turns over, and won't start. No power to fuel pump. It...

What the title says. I'm about to install the third fuel pump in this thing. I took out the one that came with it (Toyota branded) because it felt a bit weak, but otherwise had no real issues. The replacement, a Spectra fuel pump with kit and strainer, lasted about three months before finally...

Having a fuel pressure problem on my 1UZ swap. Engine is 94 1UZFE from LS400. I put on a new external Walbro 255 pump. Just recently put on an aeromotive adjustable fuel pressure regulator, -6AN lines and russell fuel filter. Set the pressure to 40 psi at idle with the vacuum line disconnected...

Hi guys I have transplanted a 1993 LS400 1uzfe engine and trans into a 1960 F100 American truck... I came to start it for the first time and it seemed to fire up straight away but only ran for a second or two and I had a massive fuel leak from the pulsating damper, I had the wrong seal fitted...

Hello everyone, I have a 92 ls400 1UZ in my 89 240sx. Im having trouble figuring out why its not getting power to the injectors or fuel pump. It has run great for the most part last drift season (i believe it might have had this same issue twice before but kinda went away on its own). The...

A very big Hi to all on this forum. :) I do have a question for all you knowledgable people out there ! I do need some help here please!!! I am currently putting a 1uzfe into my Mercedes 190e 2.5-16 bodyshell. What i would like to know is can i use the existing fuel pressure reg that is...

Does anyone get overfuelling issues on idle by running 12V to the pump all he time? As I understand it, the ECU should drop the pump rate on idle by running it through a resistor. Or does it not matter because it's running in closed loop and so the ECU will trim fuel?

Does anyone know what the DI signal on the fuel pump ECU does. Is it the strobe for the FPC. thanks al

HI all, I have an LS400 and my fuel pump ecu has packed up. I'm wondering if a soarer unit will replace the item I have. Does anyone know if an 89570-24010 is compatible with an 89570-50010 unit. thanks al

After almost 4 years, two house moves, one house and garden rebuild, a change of job and multitudes of lifes hiccups I finally have my part built Lexus powered Cobra back in my garage, in my house, next to my beer fridge, and I can work on it again. The donor of the engine was a June 1990...

I am in the process of putting a 1uz into a ln106 hilux which will all sit onto of a nissan gq patrol chassis and suspension. All of the metal work and paint etc I have covered but the only auto electrics I have done before is wiring up some speakers. The engine is out of a toyota soarer with...

Im not sure what is going on but I have tired the folowing -Fuel ECU Bypass = nothing -diagnostic port bypass = nothing -efi relay replaced = nothing -direct 12v = turns on I am now tempted to just wire in a 87a relay and be done with it all but would...

I have been told that changing from the standard toyota 2 speed fuel pump system to a single speed causes problems , so I am wondering whether this set up would work . fuel tank -------single speed pump mounted close and below the fuel tank--------fuel regulator--------fuel filter------fuel...

hi guys, i have hooked up my fuel pump using a relay driven by the fpc wire from the ecu Its a solid state relay that will activate with an input of 3-32V. the engine will start and idle for a few seconds, then start to die, then pickup, then die... Anyone have any ideas what the DI and...
