Hellow everyone,

I hope am posting in the right section of the forum.

I have R33 Series II GTST that has a Front Mount intercooler , Boost controller , Pod filter intake , Bov, Haltech Pro Plus ECU, 3" exhaust , upgraded turbo etc etc.

Now am having trouble with the car during startup. The car takes about 5-10 seconds of ignition.

I have already cleaned intake and throttle body and AAC valve as well.

My R33 has very different throttle body and half of the wires / plugs are not connected.

AAC valve is also different on this car and the wires having no plugs attached to it.

Please see this pictures attached.

Any help will be highly appreciated

thanks

Has it always had this issue or just started? Is there plenty of fuel getting to the fuel rail?

Does it start with some throttle applied?

Few possibilities is the fuel pump, fuel pressure regulator. With the reg u could try crimping the return line as u are attempting to start it

Thanks for the reply

its just the ignition Issue

Nah it doesnt get started by applying throttle its just long long startup!!

Its tuned @14 psi , it was perfectly fine till last week! , I don't know whats wrong I just cleaned intake and sensor thought it could be that.

Should I try replacing a fuel pump ?

BTW it has Cusco Fuel Catch can too (this thing is too complicated compared to one nice stock skyline I imported last year) :rolleyes:

Ok that tells me it is a fuel supply issue. Try crimping the retun line before starting.

Also take fuel line off before the rail and the amount of flow when priming.

If u are near me i could check it out with my pressure and flow gauge

I guess that could have been the problem

Okay let me explain

2 weeks ago I added Nulon Fuel Injector cleaner , Drove car back and then parked ( sunday)

Monday morning 7.20 am I started the car 1 failed attempt

2nd attempt it took about 5 second of starter motor's effort to give me a hope that this thing is going to turn on

3rd attemp was successful

So now after I wrote the reply went to Caltex and got about 20 litres of Vortex ( last time i used BP ultimate)

Car was warm and it started smoothly

so it can be a fuel issue too I suppose

I've got it service like a 1000kms ago and had changed oil filter , fuel filter , pod filter , engine oil (10w50) and other necessary things.

I shall see tomorow morning if it work properly

thanks again for the help mate. appreciate it

am in melbourne and you seem to be pretty far :(

Fuel cleaner could have dislodged some crap and its stuck somewhere else now.

Hope its not blocking an injector. that would be bad.

I had issues with my cold start circuit, so i stuffed half a Nerf dart in the pipe. Much better but not fixed.

If you wait for the fuel pump to prime the rail, does it start easier?

thanks mate

Yes I know now what the problem was!

It was that crappy Nulon Fuel injector cleaner

I used it 2 weeks ago and since then I had that problem

Yesterday I even cleaned intake of my car and then went for a drive , filled 20 litres of vortex ( last time I used bp ultimate)

and this morning car started normally!

Thanks guys for your help really appreciate it :)

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
