Method to tell if fuel injectors are clogged?
Hi, I'm trying to get a car running that has been sitting for 9 or so years. Right now, the motor cranks, but it wont fire up. Initially, the fuel pump wasn't priming, but I got it working and I also drained all of the gasoline out of the tank and put in some 91 octane. I also tested for spark on a plug, and it worked fine. Right now, I'm still getting fuel pressure, but I'm fairly sure the injectors are clogged, especially after sitting for so many years. Is there anyway to verify if it is in fact the injectors?

Take a long screwdriver & place the tip on the injector & the handle to your ear. Have a helper crank the engine & listen for a clicking noise.
Spray some carb cleaner into the intake & see if it tries to fire up.
