Problem: R32 Rb25det Neo Conversion Won't Crank

Hey guys looking for a bit of help or suggestions here,

I have recently put a rb25det neo into my r32 sedan, wired it all up turned the key, the fuel pump primes but the starter motor does not turn over, click or do anything at all.

There is no 12v going through the starter signal wire when I turn the key to start, I have checked the voltage at the starter motor signal wire connector and the signal wire pin behind the battery and these are both 0v when the key is turned to start. There is 12v going through the starter signal wire where it comes out of the ignition barrel and at the starter fuse when I turn the key to start, so I guess somewhere between the starter signal fuse and the engine bay there is something stopping the signal.

The r32 was originally auto and converted to manual so the inhibitor plug behind the battery is bridged, the neo and loom was from an auto r34, simon-s14 spliced the loom for me, it is running a manual r34 gtt ECU and the car has a mongoose m60 alarm/immobiliser which seems to be functioning correctly.

I'm not really sure what to check next to try and sort this out. If anyone has any ideas where to start that would be greatly appreciated.

Cheers,

Try disconnecting the immobilizer - how do you know it is functioning correctly if your car won't turn over?

So I bridged both immobilisers to take them out of the equation and now the car cranks over but it doesn't start.

I have confirmed the fuel lines are the correct way around, I have taken the cas out and turned manually and can hear the injectors click I also pulled out a coil pack with spark plug and can see a spark plug spark also when I turn the cas.

Any ideas what the problem could be?

      A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway.

      Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).

      I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too
