bad fuel injectors?

well i just got an fc and i'm in the middle of giving it that world's biggest tune up. i am in the process of getting the gauges to work (got the tach, fuel, speedo, and engine temp yesssss) and light up. i am also refreshing the brakes with all new pads and a brake fluid purge. and i will continue with all fluids, oils, spark plugs, etc.

okay here's my problem. it's flooding maybe three of four times a day. as soon as i pull the fuse and crank on it the put the fuse back in (de-flooding 101) it starts right up. my first guess is leaking fuel injectors. any thoughts on this? i did my search and didn't find exactly what i wanted to know. is there anyway for me to check if they leaking?

it's an 87 turbo 2. from what i can tell it's pretty much stock. it's got and hks air filter, hks turbo timer, and a mystery bov that i am still trying to figure out.

compression check first... before anything else. The majority of the time flooding is cause by poor compression.

If you have decent compression (above 85 PSI per rotor face) then you can start looking at the injectors.

But checking compression doesn't require you to rip the intake off of the motor to check, so it should be done first.

and if you are pulling fuses, you are not clearing the flood correctly anyway. To clear the flood on a fuel injected rotary engine you simply hold the throttle all the way down (without pumping it) while cranking. You should only need to pull the fuses if the car is radically (really really radically) flooded.

okay i will definetly ge the compression checked asap. and i will hold down the throttle while cranking. how long should i crank it for with the throttle down or will it start while i am doing that? i'm new to the 13b and never had a flooding problem with any 12a so i am still learning.
