R33 Battery Terminal Put On The Wrong Way, Car Only Crank No Start

[r33 rb30dett]

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?

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

mate i checked all the fuses and they are fine!

anyways i will be getting a consult cable from a friend, then do some testing with the computer and hopefully it will tell

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 ?
