Hi guys

A car noob here and i am having trouble trying to start my 370gt. Purchased one year ago and it had been a smooth sailing until now. This afternoon, I tried to start the car, the engine seemed trying to start but somehow it didn't hold. As you can see from this youtube video I uploaded 

https://youtu.be/wlh5r4GBoCg

As you can see, the dashboard and interior light were on and there wasn't "submachine gun" sound coming with dead battery as well. So far I changed the key fob battery, insert the key into the key slot, didn't work. 

It had been a long day so I ended up leaving the car in my office basement and will get back there tomorrow morning and try to sort something out. So any suggestion of the causes or solutions are greatly appreciated

Thank you all and have a good day.

They do super weird things when the car battery is even the slightest amount flatter than it likes, or is failing/has failed. Try jump starting it with a safe/electrically shielded jumper set, or a plug-in starter/charger pack.

I certainly hope that's the batter, then it would be an easy fix. Will give it a try tomorrow and see what happen. Thank you

Scan tool would be handy to get whatever DTCs are being flagged.

Otherwise, if it is actually trying to kick the starter briefly and then craps out, check battery voltage with a multimeter before and during that cranking. If the battery is in good shape, you should expect around 12.2-12.5V before cranking and no less than about 11V or so during cranking.

If the voltage remains at the non-cranking measurement you made, then you likely don't have power going to the starter. Next, check the relay coil input to see if it is receiving 12V across its coil. If it is, check if the relay itself is indeed clicking and check the power coming out of that relay going to the starter. If you see power leaving the relay, then it must be getting to the starter but perhaps the starter has gone bad. If you don't see power leaving the relay, then it's a bad relay.

We had another dude here have a problem with their starter relay, of which I believe there were two of them to contend with. From memory, they're like $45 a piece from the dealership or something but let's not get ahead of ourselves and just start with those basics.

In the video, it actually sounds that the car has started, but then quickly dies. I also note that it looks like your headlights are on. For battery issues, turn your headlights off. But, the fact that it actually does sound like it starts, I am going to guess its not a flat battery, but may be a failing battery IDK. On my previous car (350GT), I used a Bluetooth ODBII scanner connected to my phone to read the codes. It was cheap, but priceless. I just got the 370GT, so am scared to plug it in, at least till after I have sorted out my NSW registration transfer.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      Back in January, I noticed my car felt noticeably weak. I had the injectors cleaned, which seemed to solve the problem -- until now. Recently, the car suddenly lost power again while driving. Suspecting the injectors, I brought it to the mechanic. He recommended replacing them entirely, saying the current ones were getting unreliable and fiddly to work with. I could not find a direct replacement for my current injectors. The closest match I found were 440cc injectors. This led me to look into the possibility of upgrading -- and of course, that would mean remapping the ECU. From my research I found: The OEM Part numbers are 16600-72L20 and 16600-72L21 Both the RB20DE and RB20DET use the same 270cc injectors. There are much better options out there over the old OEM injectors. Nistune could be a viable tuning option. While the RB20DE isn’t explicitly listed on their site, the ECU is essentially the same as the GTS-T version - just with a different map. The ECU code on mine is listed as supported. One concern is finding a tuner who works with Nistune. Aftermarket ECU like Haltech and Link, but this would be the most expensive choice (and possibly overkill for a mostly stock RB20DE) I admit that I am very new to the tuning scene and would appreciate any insight or recommendations regarding this.   These are some SAU links where I got some of my information from for reference: https://www.sau.com.au/forums/topic/380324-rb20de-injectors/ https://www.sau.com.au/forums/topic/477396-factory-270cc-injectors/

      Anyone know this frontpipe?

      The inspectors are not forensic by any means but if you forge your documents and/or badgings on vehicle parts and are found out, the consequences are just far bigger than if you just run illegal parts. And their job quite literally is to cross reference what parts you got installed and what your papers say you got. Something as silly as your suspension being 1mm too low will fail you. Nonetheless I asked if someone knew the damn pipe and I certainly did not ask for smartassery or underhanded comments, no idea why you need to be told this. Great way to waste both our time.

      As useful as you explaining what forgery is... But then again, I wasn't aware your inspectors were also forensic experts and inspect nameplates on each component to confirm everything is original. They must inspect roughly 3 cars a year at that rate. You're right though, my comment doesn't help you in anyway, so I'll go talk to my wall now. Cheers.

      Say that to the guy that is going to fail your inspection or tow your car for illegal exhaust modifications. If you have anything else useful to say, please go tell your wall.
