It cut out on me while i was driving yesterday and it wouldn't start again. We changed the spark plugs and the crankshaft sensor, before there were no sparks, now there are sparks but they are delayed, once they start they keep going but the car still wont start. What else could be wrong?

 

Welcome to DF
Do you have a lot of miles on the engine? You could have a broken timing belt.

 

The timing belt is good, and there is only a little over 100k on the car
