You may have a problem with the check valve in the fuel pump, if this valve is defective the gas drains back to the fuel tank and causes long crank times, you can test this by hooking up a fuel pressure guage at the fuel injector fuel supply line on the top of the engine, run the engine for a moment and quickly record the pressure when you shut down, that pressure reading should not drop more than 5 PSI overnight, if the check valve is bad the pressure will most likely start to drop right away, but do the over night test anyway. If this is the problem you will need to replace the fuel pump in the gas tank.

you need to replace the coil pack on cyl 5 . it wont happen noticeable in neutral because their is no load on the motor.
