Car used to not start randomly after I bought it but would start eventually...., owner said coilpacks were getting hot.. So about a month ago on this hot day, the car would hardley idle, no power sputtering ect after driving for a while. it was absolute balls unless I let it sit for about 5 mins OFF. Then would start but problem would rrepeat every few kms. Coil packs were black as ash burnt out it seemed, so I put new yellow jackets and and new fuel pump and the coilpack loom from my gtr since the rb20 one was falling apart. And then the new fuel pump wass poping off the fuel filter..... Hose was shit around the edges. So after all this car is sweet started every time no stalls nothing drove nice skidded nice ect

Last week or so coming up to lights the revs will drop to about 500 and run stay there but not stall, when a/c is on its normal 850 ish,

Yesterday car died randomly at about 80km but it turned back on once I pulled overy and cranked it.

Drove to home and now won't start,

I have power

I dont have fuel getting pumped

It cranks but no combustion

I put the older pump in which works( connected it to power) but still nothin

I'm about to change o2 sensor

I'm also sus about the fuel pressure regs one has been changed its a nismo one with the bolt on the end.

I'm stuck Im usually fairly good with cars but this has got me f**ked, I've read some earths ect may be cause but all mine seem fine.

Any help would be much appreciated

O2 sensor has nothing to do with starting. Take off cas and turn by hand, with ignition on. check If coils are sparking, inectors clicking. fuel pump on etc

fixed.. after new pump, new relay, checking fuses ect. i found out it was a burnt out pin/wire in the boot. the plug looked perfectly fine but when i opened it up properly it had burnt it self apart from the pin or whateva so one wire wasnt sending a signal or power. this would explain sometimes starting sometime not.


such a fluke to find aswell. fml cars allright now. thanks for all your help and info guys. much appreciated.

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
