I'm not getting fule to one of my cylinders on bank 1. Do I need to take the intake off?

 

I once did this on my 94 Buick. Pulled the injectors and soaked in 90% rubbing alcohol. Then I used a 12v battery charger to open each injector electrically, and using a childs round nose bulb, forced alcohol thru them both ways. there is a tiny screen filter in the input fuel side of each injector, which might be clogged. If the injector clicks open with the battery charger, you have a good chance of clearing the clog. Using the bulb you can generate enough flow to see the alcohol stream out of each port hole , like probably 6 of them on the output side. My problem was really old bad gas and a failed open fuel filter that let all the dirty crap into the injectors and they all clogged up.
