Do you mean you pulled out coil from cyl 1 and put a old plug in it, and earthed the plug somewhere on the car and cranked it, and the coil is firing the spark plug okay?

If thats the case, then maybe its your injectors? check all your injectors are getting power to each plug. If its got spark and its not firing, then it probably doesnt have fuel. Maybe your injectors are completely buggered, or maybe they are dirty.

Did it just "happen" one day, or have you done something to your car and now its not working?

means its sparking but not firering the spark plugs are fine
All it tells you is that #1 coil is working.

Have you checked the spark plugs in 1,3,5 cylinders? Have you checked that the injectors are working - maybe they need a good clean?

what happened was i spun out round a corner when i started it again it was running on 3 cyclinders and wouldbt boost was blowing heaps of white smoke it all so burnt my boost line from my waste gate to the turbo where u put ur boost controller so it was ventin to the air thought it was a blowen head gaskit but since then have conpressen tested the motor seems to be fine hasnt used any coolant at all and the oil is fine looks brand new still

yeah i pulled out the coil pack from cyclinder 1 put a old plug in it to see if it was sparking its sparking fine so its not a sparking issue im yet to get a led test light to check the injector pulse. all so have swapped my inighter pack over and swaped my ecu with another car that was working fine did nothing different so cant be that

Doesnt mean they arent fouled.

You can check everything else on the car but with out pulling the plugs there isnt much point.

But If you dont think its your plugs, Id start checking the Diff and the handbrake cable, cause that will fix the problem.

      Slight brake pedal stutter after new pads

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

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

      By silviaz · Posted

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
