What's wrong?
Cleaned fuel injectors, reinstalled and now difficult starting.
I can get the engine to start but it dies after 2-3 seconds and acts flooded. I pull the leading plugs and there's plenty of fuel. I do the unflood procedure and it does the same.
Any ideas?

maybe you have to much gas(runing lean) maybe you have no gas preshur on your fuel rail. maybe you don't have enought spark to ingnight the air fuel mix. maybe you killed a sennsor?

I pulled and cleaned the plugs, they were saturated with fuel. Plenty of fuel flowing through the rail. What sensor?
Was running fine before the cleaning. Thought about changing plugs and wires anyway, but no reason to believe that's the problem.
Air + fuel + spark = Ingition
How can I verify I'm getting enough air?

The injectors were professionally cleaned and all grommets and seals replaced. I did remove and replace the air bleed sockets and seals in the secondaries because one broke, but I did not remove the primary air bleed sockets. Maybe I should have included all of that information, but didn't want to get too wordy.
I am woried about leaks around the UIM. Could this cause a problem this severe? I can't check with carb cleaner because it won't stay running long enough. Ideas?

Hmmm. If the plugs were saturated with fuel, then is almost certainly flooded. Do the de-flooding procedure. If an S5, you can try holding the accelerator to the floor and cranking the engine to blow out the excess fuel/oil. Tneh try to start it with not pressing the pedal. If that doesn't do the trick, follow the de-flooding procedure below.
If you have an S4, remove the plugs, clean or replace them, remove the EGI fuse and crank the engine to expel the excess fuel, add a few cc's of oil to each rotor housing through a plug hole, replace the EGI fuse and the plugs and try to start. Leave your foot off the accelerator.
I'm sure that an air leak around the manifold will create all kinds of problems, but I doubt it would cause fuel-fouled plugs.

^^ Yes! The running for 2-3 seconds is the exact problem you get from AFM being unplugged. Either it's not plugged in at all, is not on all the way, OR one of the connectors on the inside have crossed.
If it's plugged in securely, cut open the black plastic lid, and make sure all you're connections are proper. There's a pic floating around of the way it should be, search up "HAILERS; AFM"

I replaced gaskets and verified vacuum lines.
Just to verify, the AFM (air flow meter) is under the air filter? I never disconnected it but will verify the connection.
Any other ideas?
