Rb26 Wiring Issue - Ign Coil Relay And Eccs Relay

[want_33]

basically my standard green relays for ECCS and IGN COIL are about a week from my house via post and i want to start my car after finishing a conversion of rb26 into my silvia,

I have tried some standard 4 pin relays and pinning them out correctly into the ECCS relay plug and IGN coil rely plug and they didnt work, only other thing i could get my hands on are rb25 ones (these are blue not green), ive been told they are the same relay as the green one just pins are in different spots. SO again using the r32 rb26 wiring diagram i ave pinned these relays out correctly into the loom and it still doesnt start.

Either my battery is too flat to start the car now, about 11.2 volts after trying to start it for 2 days

or i pinned them out incorrectly or the relays arnt suitable. Can anyone shed some light on the subject?

of course its easy enough to wait a week for the correct relays to turn up so no smart ass comments please, ive poured thousands and many hours doing this conversion myself and just want to see it start for the first time.

thankyou

From installing 26's into 31's You need to supply 12v pos directly from the battery to the 2 relays each in question. Pins 5 and 1. The wiring for this if your loom is untouched start at the passenger side inside the engine bay near washer bottle of a GTR. It should be a large 8 or 10 pin connector. The ECU also requires a battery supply at pin 58 on the ECU main blue connector.

As i said this is installing 26's into 31's and this is required to start the engines when all other loom connection's are made.

If this does not work you may have other problems.

Cheers.

i have power at those pins no problem, just hoping that its the relays... i tried to hard wire some r33 relays in place but still same result, no fire

I played around with this too with a 26 loom into a gtr with no loom whatsoever, It took a bit of mucking around.

from memory I made a direct feed to the injector pack and one to the ecu. I did not have relays for my loom, however i used to take the relay pair out of my 33 to drive the race car so i assume most are interchangeable. I ended up using a couple from supercheap permanently. It took a fair bit of work and diagram searching to get the loom to work again after i stupidly removed the green holders for the relays without marking anything, as 3 are the same black and white. I think black and white was from the battery x2, the orange was the trigger and one black and white was for the load side of the relay and the purple and black was also load side.

There are a few other things you need to start the car with a factory ecu, however you can check if the ecu is even running by taking off the cas. If you have it right, you should be able to spin it with your fingers and hear the injectors tick away and sparks too, if one works and not the other that tells you something too

Seriously took me a few days to nut it out, noone seems to want to give away the secrets, while i had the manual, its not always as clear as it could be.

well i have the proper relays now, ill try the cas trick tho. so turn to ignition and spin the cam side of the cas? and i should get injector tick? im pretty sure i have no power to my coilpacks tho

[want_33]

ok, so when i spin the cas by hand with ignition on i get ticking from coilpacks but no ticking from injectors... any ideas?

coilpacks dont tick.. the tick u heard would have been the injectors.. take out the spark plug, attach it to the coilpack and ground it on metal, spin cas again and u should see spark if its hooked up right

definently coilpacks making a sound, as ive tested the injectors and there is no voltage there. discovered my loom is missing the gtr resister pack for the injectors
