2001 Civic wont start after intake manifold cleaning.

Since I was getting a p0401 cel for awhile, Wednesday I decided to take on this job after watching a video. After a long day at it, I got everything put back together except for the air intake resonator due to it being such a pain for me to get back in. I started the car up let it idle for a minute or two and all seemed to be working. Shut off car, hooked up resonator put tools away, and went to start up car. Car cracks but will not turn over. Walked away from it for two days.

Saturday I see I have a cel code P0113. I don't believe this would cause car to not start, correct?

I tear everything down back to intake manifold incase there was a hose or plug somewhere that I didn't connect or maybe somehow something was blocking something somewhere.

I didn't see anything different but tried to pay attention and putt everything back together.

Try to start car again and same issue.

I can hear fuel pump turn on.
I checked #6 fuse under hood and it was fine.
I had an extra spark plug that I used to test spark and it was faint orange. I'm not sure if that was due to me testing with an old plug and how much of a spark I would need to actually have for car to start.

Sorry for the long post but I'm just trying to cover everything and hoping for any ideas to turn to next.

May not directly cause a no start, but could contribute to the problem.



Ideas:
Flooded,
plugs fouled,
plugs wet,
lowered compression from fouling and flooding due to shutting the engine off before it got warmed up, may need cylinder walls re-oiled to restore compression along with using deflood procedures

carbon debris from the cleaning procedures got caught in the valves causing leakage and lowered compression......

...wait why where you removing the throttle body for an EGR code?

As well did you blast any of the sensors with carb. cleaner?
