Hey all,

I was hoping someone may know or can point me in the right direction i have done a search over the forums but didnt get much in return. I was drive the other day and this is the first time ever the car has missed a beat the engine light came on but after getting home any hooking the seach tool I have and error code 21 - No Ignition Signal (Ign Signal-Primary) and I have no idea what this really mean. The car runs normal before and after the light comes on and start first time every time till this day.

As I drove it the follow day and the warning didnt come back up so I was think maybe it have a hick up but than drove her the following day after and 10 minutes into the drive she displayed the engine light warning.(same error) did the same again to night

I don't know what other details to give you but if anyone has any idea would be great.

Well that's Just great....... I had been thinking about getting new one soon but not right now as trying to save for another house.

Thanks for this trip I'll let it run and see what other may say as well..

My C34 started doing that the day after got it. Very intermittently. But when the light came on it'd run like a pig. I checked the code with a paperclip and got 21. Did some research, replaced the coilpacks, and it's still going strong nearly 9 months later. I got Yellowjacket coilpacks delivered to my door for $420 and put them in myself. It's not that hard, just a little fiddly and I'm no mechanic. Took me 3 hours from start to finish. I checked the plugs while I had the coilpacks out too.

If there is no money in the budget for coilpacks just now you can do the quick fix - pull the coilpacks out and spray them with insulating material - there are a few threads with suggestions - and pull your plugs out and replace them if necessary but in any case gap them down to 0.8mm.

BTW I just bought a set of brand new OEM coilpacks for AU$400 off ebay - going fine in my car now - I think ke is an SAU members but doesn't currently have a lsiting.

Id suggest Selleys #401 hi-temp industrial strength silicone sealant (+ corking gun to apply) from your local hardware store for under $20.

Layer it around the coilpacks to stop breakdwon / wasted spark. Will get you by for a fair while :)

Snap,

I have just bought a set from Adam HERE for my S1 and it's all good.

self amalgamating tape is the go now apparently

kinda looks like tape, but its made of rubber

Hey thanks all I'll give that a go as I would like that car running to do a few runs down Eastern Creek strip in the next 2 week as we have booked the strip for the day to play around on it.

Sorry to dig this up! but did you have any luck from replacing the coils? having the exact same issue not missing etc have replaced 2 coils that were not genuine nissan parts and the engine light is still on :dry: don't really want to replace the other 4 if it was something else!

Thanks

Hey Hollypopx

Best thing to do is to reset the ECU to clear the fault codes and test.

I had this same fault code a while ago....it was easier for me to replace the all the coilpacks (and it would come out to be cheaper in the long run)

Now you can go for the quick fix and do what Tangles has suggested but after a while they will eventually break down...you have to remember they would have been in the car since day 1 and they don't last forever

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
