test your glowplug relay. a few failed glowplugs it would start rough, but i'm willing to bet your gp relay has failed and she doesn't want to start.

How old is the oil? not miles, months.

hmmm... still leaning towards gp relay. they can be fineky and only work every once in a while. but 4-5k is really too long to be running the oil when you dont rack up many miles....
