Basic wiring for s1 r33 rb25det engine

[Jackjc]

So guys I need some help, I've just put a series 1 rb25det from a running r33 into my s14 drift car. I've used the engine loom and dash loom (so I can use the cluster) sent power to the appropriate wires on the engine loom/ECU but I'm not getting any spark or ignition. 

The car is bare bones and has ignition, fuel pumps and starter on a switch panel, does anyone have any info on how to get it up and running.

 

Cheers

I am currrently scanning a complete guide ATM.
Here you go a few pages are missing like factory diagram but the rest will get you sorted

Cheers robbo, just had a quick browse through it, hopefully there is something in it that will help. From what I can tell I've done pretty much what it says, only difference is that I'm not using any of the old 200sx looms. 

It's basically a full track car so I just need the engine to run

make sure to have good earth point from engine to chassis and battery to chassis.
Check voltage at the CAS, coils and injectors too

Are you sure the ECU is powered up correctly? Can you attach a consult of some sort to the port to monitor?

ECU power needs the ECCS relay all hooked up correctly, that would be the place to start if the whole ECU is dead.

I'm getting a relay clicking on when I switch the ignition, it stays on for a couple of seconds then goes off again. 

I've used this pinout for wiring up my lives

that would be the fuel pump relay priming.
so ecu has power to trigger it, sure no ignition? Pull a plug and test spark, a common issue is fuel lines around the wrong way 😅

[Jackjc]

Isn't the fuel pump relay in the boot originally? Both my fuel pumps, starter and ignition switch are independently wired, basically ran switched 12v to the wires on that pinout that require 12v

Plugs have been pulled and checked for spark but I have nothing.

The second relay near the ecu isn't coming on, I'm sure one is eccs and the other ignition? I did find a pin on the white connector in the drivers footwell that powered up this relay but when checking for 12v output from it there was nothing. 

 

[Duncan]

Yeah there are variations in the looms from different years, but if you have 2 relays on is ECCS and the other ignition.

Per your diagram pin 16 should earth the ECCS relay when the ECU gets IGN on signal, so check out that part first. 

[Jackjc]

I'm guessing the one that's clicking when ignition is switched is the eccs relay.

It seems the ignition relay is the one that isn't clicking which would explain the lack of spark. Even when I put power to the pin I mentioned on the I believe f3 plug in the drivers footwell there is no 12v out of the ignition relay
