R33 Spin but no fire issue


Recommended Posts

Hello, today I replaced the spark plugs, coil packs and a fuel filter on my 95 GTST, and now, I’m getting a spin but no fire. The plugs were pregapped out of the box at a 0.835 so I just went with that number, I’m not sure what is actually the right number since my car is 100% stock, and after googling it, I get conflicting gap numbers people recommend. When I replaced the coil packs with brand new ones, the coil pack harness clips were pretty much disintegrating when I trying to plug them back in. (Pain the the ass to get them back in too) So I just ordered a new harness today, assuming that could be somewhere to start. Anyone have an idea on where to start? Is the gap set correctly? Thanks in advance.

So I just took everything apart and inspected the coil pack harness, everything was plugged in but I didn’t see a ground/earth attached to the harness? Just plugs into the coil pack and a plug to the loom. So I took the plugs out of the packs and #3 plug crumbled into my hand, to the point where it was just 3 prongs haha I ordered another harness lastnight though. So I guess I’m gonna have to wait till the new harness is in.

That will definitely be part of your problem. Did you pull any plugs after cranking to see if they were wet?

Presumably car was running before attempting to do any of this? It's the loom by the sound of things, given new spark plugs, new coilpacks and new loom... that's some decent troubleshooting. Yes there could easily be fuel on them depending how much cranking you attempted to do to get it to start again which can mess things up.

That said, by the time the loom arrives probably will have evaporated away 😛

    • The stock one will outperform any aftermarket standard position exhaust manifold. If you don't believe me, do a back to back test (same turbo, same boost, same timing) and you'll be super surprised.
    • Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it. 
    • So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up. 
    • This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O
    • A31 is pretty much the same thing without HiAIDS I mean CAS, no improvement lol. Not to late to send it.
