Hi everyone,

I have been member of this forum for a while now, but have only recently (6 months) had a R33 Skyline. I had a lot of issues with spark after I got it, so I went down the path of putting 6 Bosch Coils on a mounting plate, and ran 6 high quality bosch spark plug leads to each spark plug. I made up the loom and checked it time and time again. When I stated the car for the first time after this mod, it ran and idled fine, I didn't rev it because it was late at night. The next morning I started it up and it was running with a slight miss. Then I drove it about 1km and it stopped, and won't start again.

When I try and start it winds over three or four times then it gives a kinda kick, like it is firing out of order.

I have checked the loom I made it is wires into the module plug in the order of 1 5 3 6 2 4 now this is the same as the firing order so I am assume I have this correct. All of the coils are putting out spark, all the leads are on the right way. I have checked everything and double checked and can't find anything wrong. I even moved the crank angle sensor back and forwards to see if it would make a difference.

What I am considering is that I am thinking it is something I have done wrong, but it might not be. Possibly an Air Flow Meter has died or a fuel pump.

I am booked into to do a track day in the Skyline on March 28th at Eastern Creek, so I am desperate to sort it out before then. If it was my good old Falcon race car I would fix it in a flash, but the Skyline is a whole new world to me at the moment.

Any suggestions would be greatly appreciated.

Cheers

Adam

Have you checked to see if your getting fuel? (just pull a hose off, into a bucket and turn the key).

Easy way to test the fuel pump is at least working for a start

AFM, could be. Hard to tell from that. It should at least crank over with a dead AFM, mine was.

Why you'd change the coil/coil setu[ though is :)

This may sound silly, but check your intercooler piping, my hose came off once, and it puzzled me for days... The car was still a little drivable, only because the hose was still partly connected to the pipe.

Worth while checking.

I have checked all the hoses, and checked the fuel as well. One of the members PM'd me with a suggestion it could be that the stock ECU can not handle the coils. I have a mate who does a lot of dyno tuning investigating an ECU. Any suggestions? Haltech, Wolf?

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
