Check you are getting spark by whipping a plug out on the lead and leaning it against say the engine lifting eye. Then, if you have spark, slightly undo one of the red veins on the metering unit and crank it, it should piss fuel all over.
If both of these work, then something more sinister is amiss.
You say it came back from the garage with an overheating issue........... this is the problem I would be most worried about, sounds like a headgasket issue to me. Have they been twatting it about in your absence?
If you know al that why couldnt you get yours running at the weekend
