Fuel injectors fail generally for two reasons, the electrical solenoid itself fails and they will not pulse properly or at all. And they can become clogged by fuel varnish or debris that gets past the filter.
If you suspect the injectors, you can remove them and have them cleaned and tested at a fuel injection shop. This is usually around $25-30 each.
Lucas is a good product as well as Chevron Techron and Seafoam, but they do take time to work.
If car sits in garage for any length of time (more than a week) use a fuel stabilizer, which will prevent the formation of varnish.
