Stagea Startup Dramas

[Stick180]

Hey all,

This is kinda a last resort sort of thing.

Background info on the car: C34 S2 Stagea, RWD Auto, Front mount, Pod, Nistune, 550cc Injectors, Walbro 255L, Kinugawa upgraded standard turbo.

My stagea has had startup issues for sometime now, originally it was the cold start which i had the tuner sort out (would take 2,3,4 goes at cranking to get it to start). Now, im having issues with the warm/hot start. Sometimes it kicks over after a second or 2, other times it will take a few goes and by then the battery runs out of juice and needs the aid of a jump start to crank over. Thinking about it as i have over the last few months, i assumed it was a battery/voltage issue as when the car wont crank and the battery depletes, if i use the jump starter, it kicks over first go. I had the mechanic check the battery and he seems to think its ok. Could it be a case of this? something sucking the juice during startup? How would i compare if i measure voltage at startup with a multimeter to make a comparison?

Or could it be something to do with the tune again?

Any help would be greatly appreciated

Battery sounds like it is stuffed but I have had some minor hot start issues with the Stagea for years.

Presumably it is the AAC but it seems to be clean and I cbf trying any harder to really sort it out since it always starts even if it takes a longer crank.

New battery time I reckon.

A battery shop should be able to test your alternator output and if that is ok get a new battery. Actually ideally they can test your starter draw as well and if that is excessive your starter motor is on the way out.

Often battery tests only show if your cells are dead (voltage drop) you need to check cca cold cranking Amps of the battery with a digital test .

If comes up good like the wolverine says look at ya acc ,

Might add, starter has only been rebuilt less than 3 months ago, im assuming it met an early death because it was cranking heaps.

So points to check:

Battery CCA

Alternator - Output

ACC Valve

The missus is on my case as its her daily, and more often than not its her that gets stuck. When its warm/hot, you can litterly crank it for only about 7-8 secs collectively before the battery flattens

Just swap the battery, if you jump it and it fires, it's pretty obvious the battery capacity is ruined. (happens regularly if you let them go dead flat, even once.)

Why are you cranking for 7 seconds though? Perhaps the voltage is so low the coils won't fire properly?

[Stick180]

7-8 secs in total. Crank it for 2-3 secs, stop, wait, another 2-3 secs of cranking, stop, wait, go again...

Might have a go with a new battery then.

Thanks for the help chums

Was it the battery?

[Tangles]

It's a dead one

Been there, put up with that.

Should run like a dream once replaced.

[Stick180]

Definitely the battery.

Replaced it with a Century NS70, starts up almost perfectly now, hot or cold. Chuffed

[coparts41]

high resistance joint in the battery , put a volt meter on it when your cranking and see what you get.
