Hi this is my first post. I am having a problem with my car starting. It is intermittent and only occurs on the first start of the day. The engine cranks but will not turn over and start. Once this occurs I am not able to start it for the rest of the day, but when I try to start it the next day it starts up. The battery has been replaced and the starter and alternator have been tested and appear to be fine. There is a check engine light on for the secondary air pump, however this came on a little over a week after the problem started. I have taken it to a third party and they believe it is the fuel pump that is the problem but are not sure. I took out to Honda and they think it is the secondary air pump. It is $650 to put in a new fuel pump and $1500 for the air pump. Don't think it is the air pump as others have actually taken it out and put a simulator in. Seems not vital for starting or engine function. The car is stock except I replaced the air filter with a k&n. Need some help as I fear I will drop the money and the issue won't be fixed. It is a 2004. Let me know if I need to provide any additional information. Pretty new to this so wanted to hear what y'all think might cause this. The fact that it is intermittent is curious to me. Thanks.

How do the plugs look? Also check the injectors and make sure there not clogged.
