Also I noticed that the thin white plastic tube from the cylindrical thing in front of the "injection module" where the gas lines branch off to go to each cylinder, has broken off and it is meant to connect to the EGR valve. Also the Air Intake snorkel is cracked badly. (Sorry for lack of technical terms...)

Would this incomplete tube routing contribute to hard starting problem?

Thanks.
