cant help but you mean timing chain not belt
sorry to drag up an old thread but doin this myself and been lookin for info on doing using a solus do i just start at cylinder 1 (timing belt end) and code in cylinder order as per solus instructions?ok should be able to help a bit here.
just done mine on a snap on solus pro had to set the scanner up as a 2004 model though on mine as it wouldn't let me code if i used 2002 setup.
once you have the injector coding utility up on the scanner it's just a case of doing 1 injector at a time the codes can be found on a label ontop of the rocker cover if it's still there.
you should see 4 16 digit codes....
record these down rememberiing they are displayed in firing order 1-3-4-2.
follow the prompts on the scanner and it's worth checking the codes are correct you should be able to check using a mirror that the codes on the label are still valid and in the correct cylinder number.
enter code for injector 1 follow prompts turn igniton on/off e.t.c as required and each time you get asked if you want to code another injector just say yes and repeat all steps.
snap on code cylinder numbers 1-2-3-4 not firing order so remember to enter correct codes....
hope this helps
