heya.

how is all just wondering i just finished doing a head on my r32skyline the head was serviced and had the 12 bent exhaust valves replaced done by fhyswick heads when i put it back together all wiring is on all vacuums are on all intercooler pipes are on and everything is tight when i tried starting it it pops and cranks but dsnt fire it has injector pulse, has fuel pressure has fuel flow, and has spark.

what im wondering if anybody has had this problem before and has any advice on what it can be any helpfull comments will be highly apprecieated it has been sitting for a couple of months now so do u think its worth while taking the plugs out and skirt some oil down the bores? also when i took the plugs out they didnt have any fuel on them? and it has pressure, flow and pulse.

thanks mark hope to hear back soon

oh i dunno never thought to plug the scan tool on lol when i was trying to crank it b4 it went KABANG straight out the exhaust so timing is out somehwere all coils are going to right place and i have all the wiring on the back of them right i drew a map b4 i took it all apart lol.

but would timing out cause the plugs to be dry when i take them out? it sounds like it has compression somewhere but dont have a compression tester to check. i also know there is one blue connecter under the collector assembly that i couldnt find to anything its right under the throttle body and just above the fuel rail.

also noticed the CAS has left to right adjust ment could that be cuase it if thats wrong?

CAS should have been marked when removed and put back exactly to same position (usually neutral position in dead center), in the wrong position can do nasty things like advancing the base timing (to the left) or retarding the base timing (to the right).. (if i remember left to right correctly). Timing will need to be checked each time the CAS is taken off.

You should be able to see where the tag broke off. Now all you need to do is visualise how the CAS would have aligned. The CAS also has a set of teeth to locate on the ex cam. By the sound of it, you are 1 tooth out on the CAS mounting position.

      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.

      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
