Too much timing (cant back off any more) 5s-fe

[Cuts]

Hey, ive been working a bit on my mates 184 this is the story.

He called me about his car, it car stopped on whilst he was driving around a round about. he got help and the car was pushed out of harms way.

anyway i arrived and worked out that the timing belt had snapped, being non interference it wasnt such an issue, towed it back to his place.

Now before i started playing with it i noticed the dizzy was wound the whole way retarded. I replaced the timing belt and accediantally put it 1 tooth advanced, meaning the dizzy needed to be wound the whole way advanced to get close to 10 deg (but was still too advanced), anyway knowing this i checked the cam timing again, fixed the cam timing to the correct position, but i still cant get enough timing out of it, its currently about 17 deg.

So the basis is that the dizzy is advancing the timing too much, even with the cam timing a tooth out it still cant be backed off enough.
Unfortunatly i dont know where the timing was before i started, as the belt was snapped.

My thoughts are thus:
problem with the pickup in the dizzy
dizzy cap and rotor button (unlikely but since the timing belt had probably done 200 000 kms its entirely possible they have been in there since new)
ignition module
ecu

Thoughts????

one thing thats just sprang to mind, being that the harmonic balancer is a 2 peice, prehaps the outer ring with the timing mark on it has moved in relation to the key on the inner piece.

You can't just remove the dizzy, rotate it to where you need, and put it back in?

[Cuts]

the dizzy only mates in 1 spot to the cam, but it has adjustment, but its fully adjusted at the moment.

just checked the harmonic balancer, its correct to TDC.

Have you checked that both the cams are timed correctly.
If there out that will also effect the dissy timing

cheers Craig

[Cuts]

the exhaust cam is the slave cam and the dizzy is driven off the inlet cam.

[CraigD]

How are you checking the timing?

Just putting a timing light on then adjusting or using a check wire?

[Cuts]

shorting E1 and TE1 in the diagnosis port

then timing light

[TERRA Operative]

get a white paint pen and draw some lines on the crank pulley across the rubber join and the two sections. Drive it, rev it and see if they still line up.

[CraigD]

Theres no codes coming up when you connect the 2 terminals?

[Cuts]

no codes nope.

yeah thats not a bad idea terra, i tested the balancer against true TDC off #1 piston and it looks right, doesnt mean it'l be right when rotating though.

i had similar issues on my 185 when i bought it, turned out the rotor button was over looked, id replace the cap and button before checking timing again, at least that's one probable cause ruled out for a very low cost =)

Try craigs suggestion it's pretty much all that could be wrong and it sounds like it was out before you started so I would remove the cam cover to confirm the cams are timed correctly
it will be two dots on the cam gears which should line up together but don't forget to put in a bolt through the scissor gear before removing it

[TRD-12A]

yeah sounds like the scissor gear has spun especially considering that the belt snapped did you line the scssor gear up when doing the timing belt? If not guaranteed to be the problem

[Cuts]

i checked the cams yesterday and they were lined up correctly, but being the exhaust cam is a slave and isnt the cam that drives the dizzy i fail to see how it would effect ignition timing.

ill have another look today over the whole thing to double check.
