Re: vibration only at 5000rpm
EFI fuse fine, not blown
i tried a "fuel ECU" bypass and i could hear a swashing/pumping sound coming from the engine so i assume that the fuel pump is working. and i undid the "out" side of the fuel filter and there's petrol coming out of it.
whats the easiest way to check for spark?
As they say in the book, assembly is the reverse of dismantling, but slower cos you forgot where all the bits are

Re: vibration only at 5000rpm
So you would be blaming the vibration on missfire?
Did you say that your fuel pump used to start when you turned the key to ON (not starting the car just turning on ignition) and now it doesn't? If that's the case i don't see how the igniter would have an effect on that??
Re: vibration only at 5000rpm
i think i may have been wrong with the fuel pump noise. as it returned today when i tried to start the car. but it still just turns over but wont start.

Re: vibration only at 5000rpm + other issues
after working out the diagnostics. i'm getting the error 12 which is:
no NW or G1 and G2 signal to ECM for 2 sec or more after cranking
which i assume is RPM or ignition signal. probably the reason i'm not getting any spark? what do i need to check for the RPM signal. as i assume the ignition one comes from the igniter?

Re: vibration only at 5000rpm + other issues
Yes if the code is the same as 1G... Dont look too long at the electrics yet tho... Check your timing belt again first coz its what youve been playing with. Just say you snapped it, you may not be getting CAS and the ECU wont fire the igniter and you'll get a code 12...
I would be looking closely in the front there for your prob. Most likely place to start as its less coincidental for there to be an issue there than for another problem to randomly have popped up just when you finished servicing it.
meh...
Re: vibration only at 5000rpm + other issues
timing belt is still fine. i have the top (cam wheel cover) timing cover off and can see the belt spinning fine.
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?

Re: vibration only at 5000rpm + other issues
definitely - that "green toothed thingy" is not a pirate, its the trigger wheel for your CAS.
that'd explain the spark issue - but i wonder if that could also be the vibration you're hearing at 5000rpm - i reckon it might be due to it being imbalanced after it was bent. But it could still be the harmonic balancer or anything related to the timing case (ie all pulleys, cam wheels etc)
Good luck

Re: vibration only at 5000rpm + other issues
yeah i pulled it all back out... bent that trigger wheel back out a bit more. and put it back on the cog good and proper. and yes it fixed my issues
even the vibration has gone? so i dont know what was causing that.
thanks for all the help though fella's. guess the only way to learn is from our mistakes

Re: vibration only at 5000rpm + other issues
I'm guessing that if it was bent out of shape, everything in front of it would have been slightly out of place as well. This may have been enough to cause the vibrations at higher revs.
Glad to hear you got it fixed!

Re: vibration only at 5000rpm + other issues
I thought it might be an ignition prob (as suggested early in the thread). I doubt it was a balance prob, rather it may have caused an issue with the hall effect at a certain revs.
Main thing is that you've fixed it. Happy days!
Re: vibration only at 5000rpm + other issues
Allmost deff ignition , it would be confusing the hell out of the ecu .
