Hi guys!

Sorry i'm a bit strange and this is also my first post. Hopefully i will get some serious helps from you guys!

I currently own a R33 GTST and it was running like a dream! About 2 days ago i tried put a bigger battery on. Then i realised that i put the wrong way around positive and negative terminals. However it didn't affect to the car as all the electricals are still working, no fuse blew off. Straight away i started up the car and it only cranks... won't start at all.

I checked the fuel system and it's fine, injectors click click.

We tried to push the car straight down from the top of the hill, then put on first gear and rev it up a bit then it suddently start up and idle fine! But if i turn off the key there is no way to start it back on even it cranks.

From what i've tried i can feel the fuel pump working once i turn the key on, haven't check out the spark yet BUT if i roll it, it will start up so i guess there is nothing wrong with spark.

There are some lights on the speedo indicate fuel and water!

I will reset the ECU tonight and see what will happen tomorrow.

Please suggest me what to do! I really stuck...

Thanks guys!

I'd be 99% sure it'd be a fuse, as it's the "first defence" from the terminals.

Did you check all three fue boxes?

-Under the driver side dash

-Next to the battery

-The big black box in the engine bay

It will def be a fuse. You cant put the battery terminals on backwards without blowing something lol. Did the bit spark not give it away? :P

My guess will be one of the "Engine Control" 10A ones under the dash.

Its a long shot but it could possibly be the ignition/ecu relay next to the ecu (big blue ones)

When i soldered a couple of wires without disconnecting the battery i stuffed one of them, i swapped them over and all was good.

when you turn the key to ign you should hear two clicks from the passenger side.

just a possibility ?

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      They're all horrible. X-Trails have had a nasty sounding 4cyl since forever, no matter what engine family it came from. The CVTs only made that worse. Then the whole Renault thing only made every Nissan that was contaminated by them even worse again. The only fun I've had in a X-Trail was having it blown sideways across a frozen Minnesota highway at 90 mph trying to make it to the airport to get out of the frozen hellhole of Hoth. Nearly died. Was great fun.

      Alrighty, I'll have to grab a couple pics and type out something soon in another post. I haven't driven a modern X no, this would be the first one really. Yeah the rental boxes are always cheap as chips right? So I'd doubt that anyone was handing out GTs to go and abuse. But I s'pose I could be wrong for sure. New cars these days though? Pretty unimpressed with what I see now; 20 years and all that, like you said. It just kind of worked out to have these two cars now. I'm pretty pleased with that, don't need much else. I'm sure you lads are right about the temps and for sure, you wouldn't have much time to drive 'em down there if you all were like me. I do hate sweating all over the seats though😆

      remote oil cooler hose size, 8,10 or an12?

      Let large companies that are making money off selling kits do the preliminary engineering for you. If they all do -10, then that is all you'll ever need.

      Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.

      Are RBs worth building reliability wise

      By Hendasto · Posted

      At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!
