Hey, got some dramas with the cefiro, hoping someone can point me in the right direction.

Basically when trying to start it when cold, it takes a few turns over, before it will fire one cyl, then 2, 3. Will sit there running on 4, or less cylinders, untill you touch the accelerator, then runs on all cylinders, smooth as.

Did have leaky injectors, which have since been replaced, still the same. Ive checked all vaccume lines, all seem sweet.

If it helps, it was auto, now 5 speed, although i didn't do the convo.

Also the car has been out of rego for a while (18 months) and hasn't been driven in that time. Maybe just needs a good run??

regards

Alot of RB20s struggle starting on cold, low charge or if they havent been driven in a while. Give it a good run and charge her back up, or try replacing the battery.

Mine did the same thing, struggle to start, then start on one or two cylinders and instantly fire up the remaining cylinders off momentum. To get it started I had to help it with the throttle like a good old carby. Thats Datsun I guess. Replaced the battery and leads, now it fires like new every time :P

Yeah, come to think of it, i had to jump start it last time, and it seemed to start better.

Once it gets rego i'll take it for a decent drive, see what happens

Cheers

Have a look at what its idling at.

With the old ground lead, mine idled at 9, 11 when revved. Since the new lead, it idles 14 volt.

Other pro's; starts almost instantly, somehow more power on acceleration (maybe wasnt getting enough spark with old lead?)

Temporary movement permit > cruise through some country roads

If police pull you up and ask, say its for rego purposes. Gotta charge up the battery, right? :D

My car does the EXACT same thing. I think it might be a bad cold start valve on mine.

Post up if you get it fixed (and I'll do the same).

Well i'll let ya know how it goes, still trying to track down a speedo cable, then sould be right for a blueslip, will take the scenic route to the workshop, try and get some kays under it.

Saying that, when I let it warm right up in the driveway, (bit of charge in the battery) it starts fine.

Will check out the earth lead too.

Hey.

So yeah, took the car for a bit of a drive, seems to be much better.

Starting first kick, smooth straight away. Guess the battery just needed a decent charge.

Was a eye opener to say the least, being completely stock its rather breathless :) , but nice and smooth, perfect for a daily. :)

Cool :)

Yeah, make it un-stock, then drive it and tell us what you think :P

Dunno why they sold poorely in Japan, as stock, theyre great for daily use.

Nah been there done that, last cefiro was modded.

Plus I cant justify having a track car, and a daily slider. :(

Just glad its running smooth, air con works too, score.

G'day Glen, been ages!

Still got a Ceffie I see!

I've still got mine and it does the same, I just have to give it a little touch on the gas, and I see the volts Jump up and she's off - I don't know whether it's a bad alternator or bad battery, packs... but it'll happen every time I cold start - warm start is no issue.

I'm gonna try new coils, as the battery seems okay it's just the initial sparks don't seem to by flyin in the engine ;)

It's been a loong time since I've hit the track - mines more of a daily although Im trying to avoid driving while it's falling apart - I bought a house so the ceffie comes second now in the money pit scheme, Hope your well mate!

Yeah mate been a while!!

Picked this one up as a daily, will remain fair stock, its nice and smooth, i've got a s14 for track duties now, plus I don't need the attention from the fuzz, im too old for that shizzle.

Yeah, car is starting no probs now.

    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • 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)?
