Ok. So I was driving on Saturday, and when I gave it a bit (under full boost = 10psi) it would hit a wall kind of like boost cut at 4500rpm for 5 secs then kick into boost again.

Checked over a few things that I thought could be the problem.

1: cleaned afm and plug.

2: tightened intercooler piping and checked for boost leaks.

Nothing worked

Was running and driving fine apart from when I put my foot down.

Then this morning I went to start it up and it wouldn't kick over. So I got a new battery since the one I had was a lil old, put it in and still no dice

All the belts are moving and its just on the point where it wants to kick over, which makes me think it could be the starter motor??

Car was also recently tuned.

Car: Silvia

Engine: Rb25det

Mods include, splitfire coilpacks, turbo back zorst, Apexi avcr, apexi safc, platinum plugs, intercooler, brass button clutch, nothing major.

Any suggestions would be great.

cheers, Ben

So it's cranking, just not starting? If that's the case, it wouldn't be starter motor. To eliminate that, try jump starting it. If it starts, that'll be the problem. It still would explain the problems under boost.

I would have said coil packs, but you've said their spitfires so that wouldn't be it. Have you had any work done to the car recently?

Check the ignotion system. Is the car getting spark? Is it getting fuel? Are there any plugs that have fallen off? All the vacuum lines attached? I'd check all these first, and then take it to a mechanic.

You need air, fuel and spark to start an engine. Seeming as though you havent listed an aftermarket fuel pump (possibly meaning your still running the 15 year old standard one) under mods that would be the first thing I'll be checking.

try checking the coilpack wiring loom as this can deteriorate overtime which will also cause the car to not start apparently some people who replaced the coilpacks didnt realise that while doing it they might have damaged the wiring as overtime heat caused the wiring to be crispy and would crack easily

Changed the ECU and ignitor module yesterday, neither worked, there was no spark at all. So the problem lies between the module and ECU (as said above, in the harness somewhere).

My thoughts, it could be the resistor?

IS anyone an auto electrician on here or know someone that can come to me as the car doesn't go. For cash :P

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day  
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
    • Are you 100% sure this isn't tune related?
    • 140-150 across the board. At this point hoping the grounding harness fixes it. My grounds are all tied to the chassis and none to the battery. For SR and KA that’s never been a problem for me but had a few other guys here and Reddit who told me RB really like a very solid ground setup tied to the battery so going to try that next, I’m stumped if that doesn’t do it. Never had a car have spark and fuel and not fire off before. Only thing I can think is the spark is intermittent/weak because of grounds nothing else really makes sense at this point 
    • I am having close to the same issue. Can you help me with what wire you grounded to get your pump to trigger?
