Well today I went to the car and the car wont start. When you flick it to start you can hear the fuel pump pumping but no starter motor. Everything else seems to be working as per usual.

I checked the fuses on the drivers side kick panel and all was in order.

I checked the battery as that seemed fine, The radio / windows and everything work fine.

I disconnected the battery for 1h to see if that had anything to do with it.

Its got me stumped. I thought it could be the imobiliser but that seems to be ok too. I couldnt check the integrity of the immobiliser connections into the cars harness as I had no idea what I was looking at.

The only thing that seems different to usual is that when you move the shifter to reverse there is no revers sound on no revers lights. ( I noticed this when I tried to start it N)

Any idea why there would be no reverse lights or signal ?. Is there a fuse for the Lights that I cant find but surely this wouldnt stop the car from starting ??

Please help me as I am stranded.

I do Ill will check that ? Thanks.

When the ignition is on and where the normal gear indication is there is nothing to say what gear it is in.

Does anyone with M35 have the sear selection when the ignition is on "ON" mine saays nothing.

Hi Dan

Yes my M35 does have an indicator at the bottom of the speedo. It comes on when the ignition is on and show P, R, N etc. Have you had any work done on the car lately? New sound system etc. There is a thread on removing the centre console around the gear selector. It may show you a plug that has not been put together correctly.

Good luck

Sounds like the right idea. Sounds like the computer is not picking up the gear selector and will not let the car start unless it is in D.

Thanks Murray, I have had the contre console out in the past and it is possible that there is something wrong there, I will check the connections tomorrow and try to determine if there is something not right.

It seems weard to me that there is an issue now when it had beed working fine for some time.

yeah, no gear signal getting through to ECU, like Murray said, check harnesses. Bad connection or something left off. Also check connections at Auto ECU, drivers kick panel on C34s.

On the drivers kick panel on the M35 there is the fuses as well as some control unit and alot of harness. Whats on the C34s ? Should I unplug the plus and just make sure everything is connected secure ?

I think it would be more like the centre console as I have had this out in the past.

I appreciate your assistance.

like the others, im betting that it is the switch from our shifter not telling the ECU what gear the car is in, thus not letting it start, as a safety measure. In which case im pretty sure that that would not be fused due to it wold only send a really low amperage/low voltage signal.

sounds same as C34, Auto ecu with a large harness, probably start unplugging and replugging all the plugs on centre console first though. just test as you go.

Well everything looks in order in the centre console, The only plugs that get disturbed when removing the console are the heated seats, 4WD syncro, hazards and shifter light. The shifter mechanism has only 1 main plug and this seems good.

The AUTO ecu on the other side kick panel has a hundreds of wires going to it and about 6 connectors. Seems like a lot of wires how would you know where to start.

Did you drive it after you had centre console out ? or something that has happened well after you did any mods ?

The Auto ECU should have fused power, check for power there, the 12V wire or wires should stand out from the rest.

I had been driving I for a while, But hopefull I may have found the problem as I have located another set of fuses and relays that I will have to check tonight. Im keeping my fingers cross as this problem is driving me insane.

Well I finally solved the problem , I was reading through some V35 documentation when it referenced another set of fuses and relays that are not that obvious on initial inspection. The fuse box is located on the passenger side firewall right in the corner. To see the Fuse box you need to remove the battery cover & surround as well as the black plastic window trim.

A simple fuse was all the problem see picture of fuse location.

good to hear, big relief Im sure, any idea what caused it though ?

Yea I know exactly what caused it, When they did the compliance and installed the rear child restraints. (Mine are in the top of rear or the cabin where the tailgate is mounted) and one of the bolts had damaged the rear tailgate harness. It wasnt until I went looking for a reverse light signal for my camera and the tuner that it failed and rendered the car useless.

Basicall if you short the reverse signal to earth you blow the fuse and the car wont start.

Im glad this didnt happen somewhere else away from home or else I would have been stranded with no clue and to make things worse its hard to get the towed with the body kit as there are no accessible tow points.

Now I am trying to work out how to route the video signal through the tailgate to finish the camera install.

Cheers for you help and support.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
