basically im running a R32 with a RB25det (see my garage) it is being a bit of a b*tch to cold start the engine... i have a few posibilities from other peeps and just want a few opinions

1. Ignighter problem ($1200 for a replacement from nissan even with staff discount :ermm: )

2. Sparks(i may have got a bit enthusiastic tapping them to .8mm... will test this tomorrow :P )

3. Fuel pump (unlikely as it runs fine and is aftermarket :D )

4. Starter motor (as far as i can tell its working fine :) )

5. timing/air-fuel mix

any help on this matter would be much apprecaited and maybe rewarded with beer (not through post though)

Assuming you are running a stock rb25 with stock ecu.

Have you done a compression check on the engine?

When i lost partial compression in one cylinder, my car was a farker to cold start. At the time, i thought it ran fine, came on boost fine and still made the ass-end loose at the top of 2nd. But the moment my mechanic heard it, he knew i hurt the engine.

ok when i say a bitch to cold start i mean not runnning temp (weather doesnt affect it)[it fires but then dies or is really sluggish until it gets going, it also stalls if i igve it too much gas before it warms to running temp]...

i had a compression check done and its fine...

Stock 25 ECU...

ill look for the cold start valve in the morning as i gotta take off the body kit to get under...

as for pin 43 i dont mess with the pins ect so have no idea about that...

anyone know where i can get a diagramm for the engine as i lost mine from my computer (damn missus)

Thanks for the massive amount of response, now who wants to help me do a cut and polish :)

What spark plugs? And try opening the gaps back out to 1mm, seeing as you are running everything stock. Try starting with the ECU temp sender (2-pin connector) disconnected.

Don't understand how a body kit can get in the way of the inlet plenum.

How old is your battery?

Perhaps giving the battery a full charge or replacing it with a new or different one laying around.

Im recharging my battery at the moment as it gives my car a sluggish start.

I might be silly thinking about the battery but anything is worth a try if you can be bothered. :wub:

    • I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car
    • Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.
    • I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it
    • If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣
    • I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
