R33 Won't Run, Stopped Whilst Driving

[BigDaddy]

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

[paulr33]

well its obvious the last change you made broke it, so undo that, and youll fix your problem

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?

[R31Nismoid]

Lot of effort just because you changed coils

FYI you can get a new coil loom for like $120 from Nissan...

Sounds like the signal vlotage used to collapse the coils isn't right. You have a mismatch.

So.....regretting not just putting a set of replacement Splitfires in?

That would depend on how much it cost to do the current, seemingly failed setup.

No I am not actually, becuse I had to go down the path of an ECU at some stage anyway, it just means i have to do it now. I have decided on a Wolf V5, should arrive next week. My mate is going to tune it and should be no more problems.
