So, i've been away for a month and a bit, i came back, and sure enough, my battery is dead.

I tried to jump it off a friend's car, but no luck, my interior and dash lights turn on, volt meter shows that good current is being passed to my battery, but when i try to start, she barely cranks.

could it be that the battery is just so dead that even when hooked up to another car, it doesn't have enough juice to start?

should i leave it connected to my friends car while its running for a few minutes to try to charge the battery, and then try to turn the key?

ps, the jumper cables i got from my friend were a little thin, any possibility that the cables are just not thick enough to enough amps to crank my engine?

any input would be appreciated, thanks

As the fellas above me have said ^^

Ps How much Volts are you getting across the battery ?? Also what car is it ? If its a 33GTST or 33/4 GTR try using the contacts on the fuse box instead to jump it worth a shot..

^^You will know this 'cos they'll be too hot to handle, maybe even smoke up. Trickle charge (30bux from Supercrap) or new battery (bat may be stuffed anyway), like wives & girlfriends they do not take kindly to being left sitting around & ignored.

If you go away again for any length of time, disconnect or remove battery & store somewhere safe, preferably off the concrete floor. Works for me. :thumbsup:

When we get REALLY dead cars at work we use a few methods-

Strap 2 heavy duty jump packs onto it + jumper cables to another car and have someone reving the other car at around 3-4000rpm to charge it a bit.

From memory, i think you need more than 12.4 volts to start a car.

trickle charger wont do as its not meant to be used on near dead batteries..

goto battery world and for $20 bucks they will recharge your battery with their chargers and after that request a free load test when starting the car

otherwise u may need to replace it if it does not hold charge anymore

Whether a trickle charger (4 ~ 6 amps continous) is meant to be used on near dead (flat) batteries or not is neither here nor there.

For around 30bux you can get a trickle charger & try it. Worst case scenario you have this handy piece of gear in your arsenal for future calamities.

The only time a trickle charger will not do the job over some period of time & usually 8 ~ 24 hours is if the battery is rooted in the first place.

With reference to multi-cell batteries of any type, "rooted" = shorted (or reversed charged) individual cells, individual plates consumed/completely sulphated, full of..........etc. Obviously if your battery is past it's "use-by" date/old in the first place you will be outta luck.

For the price of a carton of Crownies it's worth a try.

It has been my experience that the battery in the car being jumped needs to have at least some charge in it. A completely dead battery needs to be connected to the (running) jumper car for around 10 minutes to get some charge before you can even think about trying to start it.

And yes, HD cables are worth the investment. I've had lightweight cables become quite hot during even the simplest of jump starts. You can do an easy jump start with HD cables, but you can't do a difficult start with lightweight cables.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
