Crank engine without starting

[zedr1]

Hi! I'm about to put my plenum back after fixing some vacuum leaks and new injectors. My concern is that maybe some coolant seeped down in the injector housing, and I don't want to destroy my engine, so i will pull the sparkplugs and crank the engine before start-up. What is the procedure for this?

Also is it a good advise to pressurize the fuelrail before installing it to se if the injectors don't leak ( new from FIC)

Thanks in advance
John
