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.

Replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot. They become corroded, due to not changing the coolant frequently enough, flood the engine, and waste a tremendous amount of fuel. The ECT Sensor has two wires going to it and is located under the distributor.

Pressing the gas pedal to the floor is the clear mode for a flooded engine. The ECT Sensor seems to make sense with the poor gas mileage and trouble starting you're having.

I would also perform the steps in the link below:

New etc sensor. Same thing.
Notice that when no start issue,while cranking, cranking noise is different, lighter, and batt light doesn't turn off.
While with normal start. Battery turns off while cranking and "bass" cranking noise.
*** any thoughts
