Hey guys.

So my car is not running at the moment, it's at my mate's Ultratune. It won't start/turn over. My mate believes the car has immobilised itself but it doesn't respond to my key. Any ideas on what could be the issue? We're thinking a new key with transponder might need to be made up?

Cheers

so it will not physically turn over or it spins over but does not start?

one is a battery issue the other is transponder.

anything else done the car?

If it doesn't even turn over, it could be a transmission N/P switch if it is an auto, or a clutch switch if it is a 6MT. Assuming it isn't a battery of course..

Hey chris

It physically will not turn over. At first, we thought it was a battery issue but when we put in a new battery, still nothing. All the electrics work though, lights on the dashboard come on, headlights still work.

This is probably a dumb question.. but you are pressing the clutch when you try to start?

I'm not in brisbane, so I can't make any recommendations for auto electricians. Maybe Chris can.

Immobiliser wont turn on anything except for say radio. Hence when immob, the you can't hear the fuel pump priming as its been cut until immobiliser releases it.

I had the same problem this morning but that is because my key fob battery was dying. My FOB wirelessly disarms when the immob is armed eg; disarming and not starting the car which cause the immob to rearm. Rather than having to press the FOB, it wirelessy disarms while cranking over.

If the fuel pump and speedo etc isnt lighting up than immob/transponder issue.

Yes we depressed th clutch. On Saturday when it first started playing up. I had to open my car manually because the alarm and central locking didnt respond to my key fob. When I opened the door manually, the alarm went off but I couldnt switch it off, because it still wasnt responding to the key fob. I put the key into the ignition and tried to start it. None of the lights on the dash came on and it wouldn't turn over or anything. The only things working were the headlights and the headunit. I tried jump starting OT, still nothing so we don't believe its battery related.

Well its exactly what i said, you have not disabled your immoblizer so car will not start, its the first thing you should have tried, new battery for your key., did u tell ur mechanic the above? if so not a very good mechanic if he didnt immanently think the immoblizer and flat key ...

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
