Zetec 1.8 16v non starter

[karlosullivan]

My GF's 1.8 16v Zetec escort broke down and now won't start at all. It will turn over, but not start, and on the rare occasion that I had to drive it, it was slow, much slower than it should have been anyway!

I was told it could have been a fueling problem (the fuel module). But a mobile mechanic who is usually pretty good said he suspects its the head gasket, as he got it started for a few minutes then it overheaded.

If anyone has got any ideas what it could be and what to try first that would be much appreciated, many thanks in advance!
