How did you set it, did you use the correct timing pins, were the pistons set at mid bore with number one on the way up,... what about the cams, were these set using the timing tools, did both tools fit into the slots on the cams.

Andy I set the bottom of the crank hole and used the tools to lock the top end but only used one of the locking pins...have I done something wrong??

Its not wrong to use just one pin but as your engine wont start it would be prudent to set the timing again, this time using all the pins, you also need to be sure that when you time/set the crank that Number One piston is on the up stroke and not the down, it is possible to be 360 degrees out.

We have a Maxisys elite in work and that will get comms with a Combo D, which model Autel did he use and is the software up to date on the machine and did he also try getting comms using the general OBD tab

Really ..... I thought the crank position would be that only point you can set it at . Does this mean that I have damaged anything?? And what's the easiest way to reset it??

Yeah thinking about it again it is the only way to set it, my bad, having a bit of a blond moment, i would still check it anyway,.. saying that does this not have the crank timing pin hole next to the crank sensor.

Yes it does.... should piston 1 be going up on the clockwise turn of the flywheel??
