Hi everyone,
I need some fresh thoughts on this one.I bought this accord 90 lx 4 door 2.2 2 months ago for my son.
Finally I had some time to spend with this. Check engine light bulb was blown had to replace it. Comes on and gives me 12 code which is egr valve right.
First week very bad gas milage. Checked vacccum lines big mess. Fix them up not yet confirmed if that is only problem for gas milage. Not time to drive around.
Here goes my main problem.
Noticed after driving for while previous day next morning no start. Engine rotates. After 3 hours it try again especially by stepping all way gas pedal it starts. Same thing every day.
Brand new:
Battery
Starter
Fuel relay
Ngk plugs
Distributor assembly "not from dealer" (advanced auto)

Already done and checked
Took out incjectors and cleaned them out
When it does no start problem I hve spark and gas, (although not checked gas pressure. I didn't find a adapter for my pressure gage yet)
Check engine light goes off when just before start so my computer is getting power.
I'm not sure that my no start issue comes from my egr valve which I'm sure is bad.
Fuel pump still does that noise before I start so I know is gatting pwer though as I said I can't be sure for its pressure.
Checked ground at thermostat housing.
I really need help guys on this one.any suggestions.
Update
Replaced etc sensor. Per txgreasemonkey advice.same thing
Notice that when no start issue,while cranking, cranking noise is different, lighter, and battery light doesn't turn off.
While with normal start. Battery turns off while cranking and with "bass" cranking noise.
*** any thoughts

Corrections to my post. While cranking and car is starting, batt light turns off and stays off.
While cranking with no start issue batt light doesn't turn off.
