    How many miles are on the vehicle? If you are 100% sure that the plugs and the coils are good, than I would be checking the joint connectors between the battery and the washer bottle, I have seen terminals back out of these before and cause misfires as well as no starts etc etc etc... Have you done a compression test? Also if you have a set of noid lights available than I would make sure the injector is being fired...
