R33 wouldn't start

[dairyboy]

Any pointers?

I've jump started it from all sorts of things from GTi-R to a tow truck with twin batteries it still wouldn't start. In fact I've melted 2 jump start cable..

It just crank slowly, crank again then crank again till the cable melts...but funny enough it did start last weekend. Any ideas? It seems like there's not enough power to the starter to crank it into life. Funny enough the power windows refused to work as well.

check your earth wire on the engine and near the battery in your boot. clean both of them and install new screws. this might fix your problem buddy.

Thanks Chucky...any other possibilities?

Will the lack of fuel do this as well?

[(B1) MR_fanny]

it might help if u have fuel in the car:D possibilities are starter motor?? did u play with the fuses?? i played with the fuses last time in my car and put one in the wrong place and it wouldnt jump start at all...it would crank over and then die. have u tried putting another battery in your car to see if its the battery at fault?

i dunno....good lucks with it

[dairyboy]

There's fuel but doesn't seem like a whole lot in there. Possibly drop another 5L in there and see how it goes...

Which fuse(s) should I check?

With batteries..haven't tried that but the battery shouldn't matter - at least with my other cars even if the battery's screwed, I can still jump start it just that it can't be charged.

off topic but who leaves their skyline for a week and leaves hardly any fuel in it ? do u care about your precious ?

[dairyboy]

Long story mate..long story

[DJ_L3ThAL]

k, was about to call the 'RSPCA' for skylines and dob in y0 ass, just treat it well

Check ya starter motor as well...

[dairyboy]

Do they have a solenoid for the starter?

[sewid]

if its cranking over then the starter motor must be ok.

[Bobjones]

If it is cranking "slowly" as stated...then it could be worn bushes in the starter motor...

coils not producing spark? spark plugs stuffed? I would say if you have cranked this car till the jumper cables have melted you would have done some serious damage to the starter, as it is only ment to run for 5 secs or so. Also, Im with Chucky, make sure your engine is properly earthed to the chassis, because a bad earth connection can make wires heat up and melt, especially when your using lots of amps when cranking.

[Sumo]

And if your +ve wire or -ve has melted that would explain the slow cranking short of a stuffed starter...

P.S. Sometimes its easier to just take it to a autoelec and they should if they are decent give you a heads up on what is going on, free of charge. I know at my work we do.

My experience has been that when the battery has totally died, and you need to jump start it, you need to have the 'jumper' connected to the 'jumpee' and engine idling for several minutes. The 'jumpee' battery needs at least some charge in it.

Also, the ECU needs something like 7V to activate itself. Cranking on a low battery will reduce the voltage available to the ECU to below the threshhold, and so the ECU will not activate, and if it isn't activated, it can't tell the coils to fire.

And don't forget, most cars have the battery up front, so there's not that much cable between the battery and the starter. The 33 has to get volts all the way up to the front from the boot.

If you can, connect the+ve jumper cable directly to the +ve of the starter motor, and the -ve directly to the engine block.

Alternatively, go and buy a new battery, and you'll avoid the "melted starter cables" syndrome.
