Before you curse at yourself for having cocked it up, check that the pip in the crank pulley is in the hole in the alternator pulley, or the ignition timing will be miles out.

TDC on compression on #1 cylinder (nearest the timing belt) is when the piston for that cylinder is at the top of its travel and both valves for that cylinder are shut -- the lobes (pointy lumps on the cam) will be pointing upwards.

I agree most people rush and throw the alternator aux pulley onto the crank and don't notice the locating hole...if you don't put it in correct position the aux pulley sits slightly bent and at an angle will cause a misfire...tons of 8v's iv done with this problem everyone try to change coil packs plugs ect... When it's just a careless mechanic putting the pulley on incorrectly

think you ment crank not cam pulley

Yup. I'll edit if it lets me.

Cheers fingers had a quick chat with Ming I was worried that the bottom end would/could be 180 degrees out but as you said if the little locating pin is in the crank pulley then it should be fine

Cheers for the reply

If your still having an issue and you live near Loughborough give me a shout might be able to pop round took me a week to time mine then a mate piped round showed me how and it was done in no time lol

Sent my flywheel off for lightening a couple of days ago and gonna strip the head for skimming 2morrow morning got headgasket kit today so will be timing it up in the next few days
Cheers

Don't forget, alto means up!

The bottom pully I managed to put in its place but I put the top pully lining up with the tappet cover insted of the side were that line is I kik started it wat are the chances iv broken somthing

On the 8v, none. Just do it again.

Is there a guide on doing the cambelt? Does the outer part of the crankshaft pulley that the aux belt goes on need to come off and if it does what bolts are they?

it doesnt need to come off, unless you wanna time it there, but it is faster to time it on gearbox side

no need for 5th gear, just put it in neutral and rotate alternator pulley to right
there are guides about cam change in cinq section, its same for mk2

Used the above picture and Tipex'ed the marks, took the senor out of the rocker cover to make sure the timing mark in that hole was in the centre of the hole and also marked the crank sensor to make sure everything was marked lol. Took it all apart to find out I had been sent the wrong kit so a quick trip to the motorfactors for a new cambelt kit and water pump and it was all back together within an hour. Just a heads up so you can check if you have the right kit. Remove/pull back the cambelt cover and if the belt is narrow (About 1cm) you have the kit with this tensioner (Hollow center):
