hi... im in the middle of wiring up my car and i screwed up... its a rb25det neo... i went to start the car... fuel pump charged up, starter motor cranked... and cranking and cranking... but no start... ive checked my spark and my injector wiring and its all correct... i then went to the computer and it smelt like the smell you dont like to smell near electrics... i opened it up and i found a diode or resistor to be had it... ive got another computer on the way but i want to know what caused it to let go... the number of the diode/resistor on the computer chip is D620... could anybody tell me what that diode is... or where can i get an electric diagram of the actual computer... if i worked out what pin fed this diode i could work out where i went wrong by using the ecu pinout... i cannot follow it back on the card because the card is multi layered or something like that....

thanks for your help

oh well ive found another computer... ill make sure that i put a relay through for sure now... what size relay do i ask for when i get it??? 10 amp???

Providing your loom came with the eccs and ign relays which is should have, then you should have a spare green relay left over near the kick panel.

Use that, if its still there.

Otherwise go the wreckers and grab another one off a r31.

    • So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...  
    • the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
    • If there's oil in with the clutch, I hope it finds its way out even if that hole has a cover/grommet 😛 I don't want oil near my cars clutch! 😛 Interested to hear the answer about covering it, I'm assuming a bung for a gearbox from another car that has a grommet to suit.
