Nm35 - Problems With Engine Starting

My missus drove home today telling me that the stag had an issue with turning on when she was coming home from the shops and there is an engine light.

So I went out and got the fault code, which made no sense, it had 10 slow flashes, then 340, then back to 10 slow flashes, weird....as normally it is 4 lots of quick flashes with a decent pause between the sets.

http://youtu.be/HuO487GeEbQ - Here is a video of the fault code and the starting issues. It just turns over and over until it starts, when it starts it runs fine. Feel no loss in power. However just then i took it for a bit of a burn into the city and it cut out once while slowing down for traffic lights. Started straight back up with no issue.

Any thoughts?

I am thinking either bad fuel causing a sensor to report errors or maybe AFM? Only reason why I mention fuel is because I recently put United Premium 98 (with 10% ethanol) as I was trying it out because BP Ultimate has hit 203.9 p/ltr up here. United up here have a rep of sometimes having "watered" down fuel.

Sounds like the cam sensors, I've not had the problem but few other guys here have and should be able to help you out, normally when it takes ages to start its the cam sensors or maybe crank sensor.

Could also be AFM or even fuel pump dying. You'd need a proper scan to see what the fault says

I am soo hoping it is nothing major. In 1 week we have our wedding an the stag is required.

Might clean the AFM and connectors to the cam sensors. Might ask around and see if anyone up here has a consult to suit that I can borrow.

Well I cleaned the connector on passenger side (bank 1 yeah?)

And since then I have started about 6-8 times with no issue.

*fingers crossed*

Might see is Nissan in Perth (family flying up for wedding) have any and get them as spares. The Nissan dealer up here is fckn useless at the best of times.

So after starting and running like a dream all of yesterday. The damn thing started playing up again.

It seems to fault only after the engine is at operating temps.

Hopefully going to get it on a scanner today to confirm.

Got a price on both cam sensors and crank sensor (figured handy to have on hand) - $580 + $25 if i want the parts this week.

Dont pay that FFS.

Get them from the US, it'll be a heap cheaper. Check out the Z parts onlines sites, http://www.conceptzperformance.com/

There are others, so I don't know if thats the cheapest.

I am not planning to...unless I have no other option.

Just rang 2 dealers in Perth and one wanted $625 for all 3 (talk about butt hurt), the other $550.

+1

I think these are the current part number you're after if you want to search around (correct me if I'm wrong guys).

Drivers side Cam : 23731-6J90B

Passenger side Cam: 23731-AL61A

Crank Sensor: 23731-AL60C

~$80 (US) each plus shipping etc from conceptz and similar prince from amayama. Not sure how easy they are to DIY.

I was only going to replace faulty sensor but keep spares (always handy).

I am going to get the intermittently faulty sensor from Nissan dealer, and order the rest from CZP so I have em on hand.

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
