Swapped Injectors, Losing Preasure

SonicVQ

Let me back up to understand the background:
You had a misfire and replaced all the fuel injectors. Since then, the car will crank more than usual before starting ONLY if it has been sitting.

Is the misfire gone with the new injectors?
Where did you buy the injectors and what brand are they?
(There are MANY fake/cheap/counterfeit parts available today that cause endless problems)

Your fuel trims can be seen using any OBD scan tool, even a $10 EL327 and a $7 app will show you.

Just to cover all bases, the fuel trims will tell us if the engine thinks a bank is rich or lean and by how much. Very useful for troubleshooting air/fuel problems.

From a troubleshooting perspective, what tests did you do that lead you to replace all the injectors?
There are tests that can be done that can tell you which injector is bad or which ignition coil...

AND they are much cheaper than throwing hope/prayers and parts at the problem.
