Car has had a hard time starting recently.. it takes a couple attempts to get it to start or if i get heavy on the gas.. Looked under the hood and noticed that a couple fuel injector O-rings?? were very cracked and broken.. Im guessing this would have an effect on the starting?? If so.. what would be the easiest way of going about changing them ?

 

Pull the rail, replace the damaged injector o-rings, and make sure you put some type of lubricate on them before reinstalling the fuel rail.

 

easy enough..

 

Also check the fuel pressure regulator for a leaking diaphram.
Just pull the vacuum reference line off, if gas comes out, its bad.
