Also tested the 1 and 120 degree on the cas and I am getting 5.6v

Cas is tested and is working. Coil amp is tested and working. Injector dropping resistor tested and working. No spark from plugs and no injections clicking when cas is removed and turned anti clockwise. I've tested the power at the cas and I am getting 12v on turning the key on but once the fuel pump stops priming it drops to 8.7v and then when turning the engine over sm only getting 10.5v but after a few seconds it stops to 6.7v until I stop turning engine over. ECU pin 58 is 12v pin 59 is 12v pin 49 12v. On turning the key but once pump stops priming pin 58 stays at 12v pin 59 and pin 49 drop to 6.7v And when turning the engine over all 3 pin drop to 10.5v but after a few seconds of turning the engine over pins 59 and 49 drop to 5.4v and stay like that until I stop turning engine over and they go back to 8.7v. All loom earth points are good as have given then a good clean up to give a good contact to engine. What could be the problem.

What sort of voltage should I see at the cas when the engine is not turning over and when its turning over same thing for injectors and the injector dropping resistor.

Its a s1 Stagea rs4 auto. Rb25 and auto box removed. Rb25/auto Engine to ECU loom removed and replaced with a 260rs engine to ECU loom fitted. Coil amp tested and works fine and a second amp used as off a running 32gtr. 33gtr cas swapped for a 32gtr and a 33gtst. Injectors dropped resistor swapped off a working 32gtr. Gtr ECU I got with engine had also been swapped for a 33gtr ECU. Everything I can thing of had been swap force good working item but the engine will still not start/run the engine will turn over. Any help on this.

Not getting any spark or fuel I've been through ever plug. Fuel pump is primeing the fuel rail so fuel is getting to the engine but not into the engine so the CAS has been tested and a spear I have knowing that works still nothing. Tested the igniter that's fine. Tested the injector dropping resistor that's fine as well so now thinking that it could be the ECU that's f**ked.

I've done a search but cant seem to fine any thing about the coil amp. How do I test the coil amp as I dont seem to be getting any spark. If the coil amp is dead how do I convert to a non coil amp loom like the std stagea rb25 in the 2nd pic.

No it was from the stagea ECU pin out diagrams I got and the resistor is located on the side of the chassis leg nxt to the radiator on the drivers side Stagea std boost control solenoid is in the same place as a 33gtst but from what I can see by looking st 260rs pic via Google the boost solenoid is inbetween the brake master cylinder and the inner wing where the throttle cable goes through the bulkhead. Not bothered about boost control at the moment as I'll b just using waste gate pressure.

Dont have to worry about AC as I've removed it as the pump was not working and there was no gas in the system. ECU is not plug into the gtr/stagea loom I made up. 260rs loom is on the floor and engine bay loom is hanging out the front.

I have figured out what these 2 are. Pink wire is the line pressure solenoid valve (dropping resistor) And the blue with red trace and silver dot is the aac valve. So the question now is what is the line pressure solenoid control valve. Is it to do with the auto box of is it ti do with the 4wd pump that's on top of the rear diff for the centre diff.

I had the same problem looking through the stagea manual you sent. Pulling the engine bay loom out is not of the question for me.

Engine bay loom is still in the stagea What is pin 17 on auto trans in 32. The only wires that are the same colour on both plugs are the big yellow wire big white wire and the big black with white trace wire. If the 4 small wires wear the same colours ied just swap them around in the plug but no stagea std engine bay loom got to be different to stagea 260rs engine to ECU loom

Not the big wires there fine I know what they are its the 2 small wires the pink wire and the blue with red trace with 1 silver dot. There yhs 2 wires I need to know

Becos that ECU and gtr loom came from the same car and the 260rs loom is the very same. All the wires colours goin to the ECU plug in both loom are the same. But like I say in my last post if I can find out what the 2 untapped wires are in the 3rd pic I could work out what the are in the ecu.

If I could figure out what the 2 untapped wire are In the 3rd pick that are in the stagea engine bay loom i could prob figuer out what pin thay go to on the ECU. There are only a hand full of s1 or s2 stageas that have had a rb26 swap here in the uk but they are not using a std gtr ECU as they are using aftermarket ECUs.

1st pic is the white plug with the 4 wires labelled to where they go according to ECU pin out diagrams. 2nd pic is of the wires in pins 35 36 and 37. The 2 wires taped together are the front AFM in pins 36 and 37 the single wire is in pin 35 but evu pin out diagrams say that the afm but as you can see it is not. 3rd pin is the 2 plugs on the stagea engine bay loom. The black plug in at the bk is all auto wires but the 2 wires in the white plug that are not got tape on are the ones I don't no where they end up on the stagea. 4th pic is as you can see the ECU

The white plug is the plug that the engine bay loom plugs into the engine to ECU loom by the passenger headlight on the stagea. The engine bay loom had a black plug and white plug but the black plug is not used as it holds the automatic transmission wires to the engine to ECU loom. Yes I will get pics of the white plug on the stagea and of the 26rs loom as well as the ECU plug where the 2 wires go to pins 35 and 55 as well as afm wires to pins 36 and 37 plus ecu number.

Ok but the front afm wires in the 260rs loom plug gose to pins 36 and 37 and the throttle valve switch wire hose from the the throttle switch to the pin 54 in the 260rs loom plug so the 2 wires in the white plug tracing them vis the wire colours and via a multimeter go to pins 35 and 54. Must say the ECU and the 33gtr ecu to engine loom came from the same car and the 260rs loom is identical the gtr loom with the only difference being the injector resistor plug is by the white plug that's nxt yo the headlight.

I am goin to be using the 260rs loom as the first loom of a 33gtr/stagea did not work. The 260rs loom is untouched and no damage at all to any wires or ECU plug so it's a std 260rs loom. 2 wires from the small white plug I've traced to pins 9 and 19 there fine its just the 2 wires ive traced to pins 35 and 54 that's the problem and where they go in the engine bay that.

The pin out diagrams I have are 2 that are 32/33gtr and 1 33gtr and 1 that just say gtr and they are all the same. That will be grate.

As the title says Ive put a 33gtr engine and gearbox I my s1 stagea. The 260rs and GTR pinouts are not the same as all of the pin out diagrams I've found and I've even got the r33 workshop manual with wireing diagrams. On all diagrams pins 26 and 27 are rear AFM. Pins 34 and 35 are front AFM and pin 54 is throttle valve switch I have got a 260rs a r32gtr and a r33gtr ECU to engine loom and all 3 ecu ends are the same for the pinouts. Pins 26 and 27 are the same as the ECU diagrams but pins 34 and 35 are not the front AFM as they are at pins 36 and 37 and that pin and pin 54 is not the throttle valve switch. Dose anyone know what pins 34 and 35 and 54 are I need to know this as the first 33gtr/stagea ECU to engine loom I made up is no good as soon as the battery is connected with out the ECU plugged in and with the key out of the ignition the dash is all lite up like if the key was in. When I pull the 2 plug apart I the engine bay that connects the engine loom to engine bay loom the dash lights up with key in ignition. So I got a proper 260rs ECU to engine loom. When I came to plug the small plug of the engine loom to engine bay loom that's when I noticed that the 260rs loom only uses 1 of the plugs and where the old rb25/auto useds both plugs. I figured out that most of the wires in the black plugs is auto wires to old ECU as that 4 of the wires In the white plug goes to pins 9 19 35 and 54. Pone wire goes to pin 9 that is A/C relay one wire hose to pin 19 that is power steering switch and the other 2 wires to to pins 35 and pin 54. A/C wire and power steering wire in the white plug in the engine bay loom I found but the other 2 wires in that plug I dont no where they go. So all I all what I need to know is what is pin 35 and pin 54 on the ecu and where does the 2 unknown wire in engine bay loom go to. Any help on this will be much appreciated as I've been scratching ma head for the last 2 days (well 24hrs) to try and figger this out.

So of I put the stageas loom bk in but connect gtr loom to the rb26 will it start and run

Its awd

PM sent regarding 34gtt stagea worshop manual.

Hi all. I am doin a complete 33gtr engine n gearbox swap into s1 stagea (will keeping it standard) and I've come across a big problem. I've got all engine to ECU wiring looms for the rb26. When I took out the stagea engine to ECU loom out I did not release that the 2 small plugs are completely different to the rb26 engine to ECU loom. The big plug I know goes to the ECU it's the 2 smaller plugs I dont no what they do. Has anyone on here done this complete swap n if so how did you get around the loom plugs and how did you find out what plug dose wst and what wire is wat even tho the wire colours are different between the 2 looms. This is the only thing yhsy is holding me back from completing the swap over. Thanks.
