Stagea Startup Dramas

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

Josh

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.

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?

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
