Of course there are two things you need to make an engine run. Fuel and spark from the ignition. You need to check to see if you have both. If you can hear the fuel pump running when you turn the key then it should be working properly however sediment may have blocked the fuel filter and will not allow enough fuel to the injectors. You may want to replace the fuel filter. If you said it will not start with starter fluid then the problem must be on the ignition side. I would check the ignition module, if you have a distrubuterless ignition which I believe you have then the module is located under the coils. Also the crank position sensor may have gone bad do to oil infiltration and will not allow spark to happen. If you have a 4 cylinder with a timing belt it may have broken and that may be the problem as well.
I would approach this systematically and eliminate the obvious by checking spark and fuel then proceeding to find out what may be stopping one or the other. Once you find out the problem is solved. Good Luck!
