Last fall when developing starting procedures in cold weather I suspected leaking injectors were causing flooding problems. I sent my injectors to "Cruzin Performance" in Michigan to be flow tested and cleaned. http://www.cruzinperformance.com/ As it turned out, they were OK but it eliminated a possible cause. Follow Cruzin's instructions on the website - you must make an appointment to have your injectors examined and cleaned! He does a flow check before and after cleaning and emails you the results. Plastic parts and "O" rings were replaced and the injectors painted. A detailed report is included. He does nice work.
FWIW, my cold starting problems were eliminated by this method: 1. Fuel pump ON. 2. Mixture RICH. 3.Crank engine. 4. Cold start ON 5. Cold start OFF when engine is running somewhat smoothly. 6. Mixture AS REQUIRED as engine warms.

These were the used Mazda injectors supplied by Bruce T. I have a new
set of Ford injectors, and probably should have used them. I would
have had to modify the intake to get them to fit and the old ones
seemed to be working OK so I didn't change them out. I'm planning on
testing the primary injectors at some point and will report the results.
