Car wont start

Ok - earlier thread, needed to supply a cable through my bulkhead for my horn. Took dash apart and managed to get one through.

 

Put dash back together, put connectors on. All ok apart from the last connector which is an extra switch which 3 cables go onto the back. It was going dark and I thought I had the cables on right, except when I put the last one on I had a little blue spark - then I realised that a) I hadnt removed the negative on the battery, and b) the keys were in the ignition and it was on (I know, plank - but I had been checking each connection as it had gone back on to make sure it was working) I straight away thought blown fuse, but checked everything and it seemed to be working. Up until I came to start the engine.

 

Key in - one turn, everything fires up, on dash, lights, stereo, fuel pumps etc. Second turn - everything goes off.

 

What have I done - any ideas?

what was the plug you came to reinstall?

 

have you checked all the engine bay fuses as well as the ones which are, i think in the drivers footwell kick panel (may be wrong?)

 

 

It was an after market switch for my Nos. It has three pins on the back which said ac, live, ground I think and I had two red wires and a black one, so I put the black on the ground :(

 

 

Havent checked the engine bay fuses as it was by then dark. But if I'd blown a fuse, surely nothing would happen on first turn of key?

Was it when you plugged the hazzards it? This screwed up my car, there is something random that fit in the hazards that wrong!

 

 

Hazzards are working, but dont know if the car was after as I put all the plugs back in before trying to start her. How did you solve yours then after that?

I was hoping it could just be a flat battery - the car hasnt moved for over three weeks :( But usually you get a clicking sound when its trying to turn over. Wished I'd had a couple of more hours of light!!

I bet its a low battery Jo

 

My original J spec one did that - lights on, turn key, nothing - do you have a binging sound when you put the keys in?

 

Id check all the fuses tomorrow, and also check the main ones. its possible that the dogy NOS switch could be wired badly

hope ya get it sorted dude:cool: i wouldnt sleep as ib be trying to figure it out lol:d

 

 

Tell me - stuck at work today so I'm going to be a little distracted from my work. Tried to turn her over this morning and was having exactly the same problem as last night so guess I'm going to have to try a quick charge tonight and hope.

 

At a show on Sunday so you bet this wont be an easy one, and I'll find out i need a part 5 mins after everywhere closes.

I hate to pour cold water on this one, but what about the spark, with the ignition turned on many important circuits will be closed allowing what ever surge that was caused to go through the system.

 

Trying pulling you EFI fuses and reset the ECU, fingers crossed. If its auto I have a working spare, wont need it now as going AEM.

 

EDIT

Just checked your garage, I guess you are aftermarket ECU now anyway.

Jo. Is it ok if you turn the key to position 1 (accessories) but everything dies if you turn it to position 2 (Ignition on)??

 

If it is I'd think it is something to do with a fuse protecting the ignition circuit prior to the ignition relay. The NOs switch probably pulled too much current when connected & blew a small protection fuse.

Great in position one - dead in position two. Any idea which fuse might have blew, or at least where to start looking - engine bay or drivers footwell :(

 

 

I'm also running AEM Terminator, but thanks anyway.

 

Cant believe how stupid I was . . rushing to get the job done!!!

 

Oh - btw, Nos shouldt have been drawing any current me thinks as it was at the time disconnected at the other end??

There's a 30A fuse from the battery feeding the ignition switch. Its labelled AM2 and should be in the fuse box behind the battery.

 

This goes to 'Relay block 2' on the 'left side of engine compartment'. In this block is the EFI1 and EFI2 fuses. I'd put my money on these two, although they are both 30A also.

 

Check all fuses in this block as there may be something not obvious controlled by one of the accessory fuses that could knock out the ignition, especially with an aftermarket ECU.

 

Also check your ECU for additional protection fuses etc.

 

Good luck!
