hey all, my r32 with rb20DET is getting harder to start, i have to pump the accelerator to get it to start, when its warm its fine, any ideas? btw plugs have been regapped to 0.8, ive got a fmic, HKS evc, apart from that its stock as a rock.

theres a cold start valve on the r33. i think the 32 has one, and its easier to access. that could be your problem. it opens up to allow more air to the intake until it gets warm, then shuts.

if your idle is steady once started, i would assume your aac valve is working ok.

well thats what i thought lol, guess it just needs more air??, had a knock sensor trouble code and it just sounds normal when starting, cant really describe any odd sounds, just my fuel pump turning on and it cranking lol

really???? most cold start setups are richer.

check that the TPS is setup correctly

hold on. do you mean pump your accelerator before cranking it? or when you start it, it needs gas to bring the revs up or it stalls?

hey mate my car has being doing this. If i don't pick the revs up to about 1500rpm as soon as I start it it will stall any ideas what is causeing this only happens when the car is cold.

Just a thought, but could it be over fuelling? maybe almost flooding of sorts. I know whenever I rejetted a carby & went too far I would have to hold throttle open-not an efi I know but you have changed the amount of fuel going in it may be messing with cold start map

Ive had this problem with my 32 and my main factor was the afm ( air flow metre ). Its running good now besides from the pumping of the gas when car is on, try the AAC valve, give it a clean, its located at the back of the plenum near the firewall kinda, cant miss it.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
