Trouble starting

I use a fuel injector tester , It pulses the injectors and with a pressure gauge hooked up you can watch how much the gauge drops which is checking flow of each injector.
You can test all of them to make sure they are flowing the same . This will pick up problems with clogged injectors or if they are not working .
