FIAT Bravo and Brava - Bravo Starting Problem - allan doc

My car has nt been able to start for over a week now. The car turns over but will not fire up. After turning over there is a smell of fuel. I thought it might have been damp spark plugs so I bought new ones. The same happened. it still would not start. I then checked the plugs for a spark and there is a spark present. It has been very cold up here so dont know if that could be the probem. A few days before this happened the fuel injector warning light came on briefly but went off again while driving. It did not effect the performance of the car. Can anyone give me anymore ideas of what else to try before I tow it to a garage. Thanks
