hi everyone. started a thread in the transmission section but i've moved it onto here as its not really transmission related
i've just done the 100,000k service on my car (timing belt, thermostat, fluids, plugs etc) its a 92 TT auto
when i started it, let it warm up a bit, i reved it out but at 5000rpm it started to vibrate/make noise all the way through to 6000rpm then instantly the noise/vibration would disapear.
this would happen not matter what gear i was in (neutral, park, drive) and what ever speed, my boost gauge was showing i was making 9 - 9 1/2 PSI when i took it for a drive
i doubled checked my timing to find i was out about 5 - 10 degrees, so today i pulled it apart and reset the timing to where it should be at TDC
so i started it up again, let it warm up a bit, slowly reved it out to 5000 the vibration was still there reved it to 6000 and the engine stutterd and died,
and now the bastard wont start again.
the EFI fuse is still all ok. and i did the fuel pump ECU bypass and i could hear a swashing sound coming from the engine, but it still wouldn't start

to me, it sounds like your harmonic ballancer is slightly out, maybe not on 100% straight, and is only causing the vibration in that particular revs. from memory, the harmonic ballancer is keyed, so it should go on only 1 way. give that a go. it is definately a mechanical related issue, misfires don't cause a vibration of sorts, more like a caughing and spluttering if it is air / fuel related

i used to crank pulley to get the balancer off, but i had to give it a few taps to get it back on. but its not like i flogged the crap out of it.
anyone want to suggest where i should start to actually try and get the engine running again. as i can't even start it now. it just keeps turning over and over.
i actually have ANOTHER problem now as well. the clip that goes to the FIRST coil pack has snapped and now all i have is just the 2 wire connectors, one is green the other is orange and black. i can still put them on the coil pack but i dont know which way they go?
could these 2 wires have touched and shorted something out (fuse somewhere) causing no spark, meaning my engine wont fire?

it may have gone on crooked when you put it back on, but as for not starting, it is a minor possibility, so the best thing to do is start by resetting the ECU (just unplug the battery (negative only) and turn your headlights on or hold your foot on the brake to totally discharge all power from the system. then re plug the battery on and try to start your car. otherwise what may have happened is it has shored out your igniter. as for any other ideas. i don't have any. probably ring your closest import specialist and query them

hmmmmm usually the ignitor is fine unless you disconnected the battery and connected it up again many times. this has been known to kill the ignitor.
When I did the 100k on my JZZ30. it didnt start either. same problem you had.
What happened was when I bolted the alternator back in I squeezed the crank angle sensor cable between the bracket and the alternator It was night time and with my spotlights I couldnt quite see down in there properly.. anyway..
Unbolt your alternator and check to see if the crank angle sensor cable has not been crushed by the alternator. because the resistance changes the ECU will not let the ignitor work.

something i just rememberd thouhg, when i was removing this cog to replace the main seal. i forgot to remove the little sensor thing on the right (blue) and i bent the star shapped wheel thing (green) as i was pulling the cog out.
i kind of bent it back into shape to get it back on. as i thought it was just a washer style thing
i only noticed then that it goes up against the crank angle sensor. could this be causing me my troubles?

yeah i put everything back, the way it SHOULD be. and i got spark and the car actually started.
kind of embarrassing when i think about it. but i guess this is how i learn.
just waiting for the battery to charge again, and my oil level to settle, my full sump has gone down to just over L from having having up on the stands me thinks.

is there anyway to test the igniter?
