hi all,

on the weekends, which most of you may know living in NSW it was very very windy and rainy. what made things worse is that after work at about 11pm my car wouldnt start up. things which i had already checked is the battery, air lines, afm and fuses. wouldnt think it is the spark plugs as they were only changed not long ago.

basically the car keeps on kicking over. also checked sensor and was connected. anyone has any other suggestions??

things i think are maybe the fuel pump or fuel relay but not too sure...

Hey,

Check all you fuses, under the dash and in the engine bay, replace all that are blown.

Check for fuel, pressure and injector pulse, should smell fuelly after cranking for a little while.

Check battery voltage is high enough, should be if it is cranking fastly, if slowly, charge your battery.

Check for spark at all of the spark plugs.

Make sure any immobilisers are disarming.

Further than this you will really need a workshop.

Did you check if you had petrol..lol.

Could be your pump...is there any noise coming from it when you switch the ignition to before crank?

good luck...

yea when its switched to on it makes like a bit of a whirling noise. there is a full tank

sometimes the noise disappears but when i put throttle down to like 20% it comes back on but only when it is at 20% and nothing else...if that made any sense lol

When you checked your AFM... how did you check it?

Quick test is to unplug it, then try to start it with about 50% throttle. If it catches but barely runs then you have the old "dead AFM for no apparent reason" problem.

A mate had this, but when I hooked up Consult to it, it said that the AFM was reading voltage. No errors or anything. Weird!

      Did tie rods. Steering now not "springing" back.

      No. GKTech arms have spherical bearings in them. No bushes. You will not need bushes for those arms. The sphericals are a bit of a maintenance nightmare. I have replaced all of mine several times in the 5 or so years I've had them, and I have the arms out regularly to clean and lube the balls. Worth the pain on an R32, because the standard arm design is trash. If you need the camber adjustment, there are other options (than the GKTech ones), although I would still lean towards and prefer the GKTech ones, even with the maintenance load of the sphericals. The caster adjustment is also highly valuable, allowing for setting the car up to drive straight. There are a million options for these, including the GKTech ones. I've had Tein rods on mine for 20 years and the balls are much less trouble in that location. Never given me a moment's pain. All positives, no negatives. I consider them compulsory.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Thanks for all that information I appreciate it. To answer your questions: - Yep that's what I mean. These guys are professional painters to so I must be missing something. It's a bit hard to explain. - With the primer landing on clearcoat, I make sure that the surrounding clearcoat is scuffed to 240 grit as my epoxy primer says that I only need to sand the area to 240 grit. - Yeah so similar to the first question, assuming that the paint landed on the unscuffed clearcoat because I've seen that happen. - Yep I want to prep the surface in that order. Only reason because epoxy primer will protect it from rust and I need that atm with this crappy Sydney weather. I think I was worried about time, if I try to put the filler down but screw it up somehow and I don't have time to sand it off and reapply it then need to put primer later that it might start to rust again so I wanted to apply the primer as quick as possible to not deal with rust.  - I just deleted some answers, I just realised after watching a video and what you said about looking at the data sheet, that I need to read the data sheet on the specific filler I'm using. It's possible now that I put epoxy primer first was a waste of time and need to go to bare metal lol

      I did. I went to a suspension guy and he told me because I don't have adjustable camber arms it's the reason why my car veers towards the left if I take my hands off the wheel but if I drive my other every day car and take my hands off the steering wheel it goes completely straight. I think it's common with Skyline's. In order to fix the problem, I likely need gktech camber arms then nismo bushes since I have poly bushes atm, then a wheel alignment after that. With my car if I take my hands off the steering wheel on a really bumpy road before stopping at a light I have to hold my steering wheel somewhat tight otherwise my car will legit just go completely in the other direction quite quickly and I'll slam into something lol instead of stopping straight. I Believe this YouTuber had the same issue and fixed it with gktech arms. At timestmap 6:05 he talks about how the car doesn't veer anymore after installing these arms.
