So cynical. Was just working on the honesty system. I can be a bit old fashioned like that. If you or any of the mods want to pm your email address i'll add you to the GFM team.

Hey guys, It seems that whenever someone has a question there is a couple of people that always turn up with an answer. Sideshow and Gloverman are the first to spring to mind. These guys do this stuff for work and they drop in here to help us out with our hobby. If they have helped you with a...

Hi guys, Couple of questions about ecu wiring for a manual conversion. Its a 92 SC400 motor in a LH torana. 1. Is the Neutral start switch needed? Will the engine start ok with it removed? 2. Does the ecu need a gear signal (L or D) to drive properly. 3. Is STP required? Does it do anything for...

Try turning the car on then taping the EFI relay. I've had this issue with my car. Efi relay not closing or getting stuck on.

Manual gearbox conversion

Thanks Guys. i got one off the fuel rail on my spare engine. Have to have a clean up in the shed.

Anyone know what the thread is for the vacuum banjo bolt? I put mine somewhere "safe" and cant find it. Going to get a new one.

is it a relay/resistor version or fuel pump computer?

The hose is for the charcoal canister.

Hi, I'm after a w58 shifter housing and shaft. the 20.5" one Anyone got a spare in a blown box? Cheers

HI Guys, Found this https://cardiagn.com/lexus-sc300-sc400-1991-1992-1993-1994-1995-1996-1997-1998-1999-2000-service-repair-manual-pdf/ Might be helpful.

I have just found that a 5PK735 fits perfectly for just running the alt

I know your just trying to flog your tacho relays : p the ecu has an output for running fuel pumps, what i need is a relay that will trigger at 2v. ive got one that will trigger from 3v, so it only picks up the high speed signal. I know it can be worked out with a transistor to bump up the...

but i like complicated. yeah, i was thinking about ditching the 2-speed pump idea. dont know how the pumps will respond to lower voltage. efi relay is trigered directly from the ecu.

I did the wiring. striped out the harness from the donor car. fuel pump is triggered by FP pin on the ecu for high speed and oil preasure for low. The engine stops ok. fuel pump runs for 5-6 secs after engine stops, till oil press drops probably. i noticed that when i run the engine for a...

swaped all three relays in the box around. same result. just noticed there 22A relays. and im running 2 fuel pumps through them. might be welding the contacts togeather. i'll try running the pumps from a different source.

One tube goes to the vac solenoid on the lhs of the inlet manifold, its connected to the throttle body via a pipe that runs around the frount of the plenum.

i tried changing the ecu to a crown one i have, relay turned on and off but engine wouldn't start. changed back to uzz31 ecu, and had relay prob again. ran the engine for a few minutes, turned it off, relay turned off. it fixed its self

The efi relay is staying on after i turn the engine off. im sure the ign switches are turning off properly. can anyone help?
