First of all I checked all the old posts regarding no start problem.
Car has 40k original miles and ran great. Excellent car. Yesterday morning, went out to start it. Able to crank the engine but it doesn't start.
Battery is fine.
Checked for spark and there is spark.
Cleaned and tightened the ground on the thermostat housing.
I checked all the fuses, both under the hood and under the dash. All were fine.
Checked the main relay and all soldering points look excellent. No cracks detected. The car was in a mild California climate until 2014 when it came to Arizona
When put key on the ONII position (but without trying to start the car), I couldn't hear the fuel pump prime.
Based on this helpful post http://www.clubcivic.com/forum/threads/no-power-to-fuel-pump.210565/
I did the following.
Removed the main relay under the dash and connected Terminal A1 to Terminal A7, using a wire. I could hear the fuel pump run, even without having the key in the ignition
Then I connected Terminal A5 to Terminal A7. I could NOT hear the fuel pump run.
Next, with the main relay in place:
When I grounded A8, I could hear the fuel pump.
Since the fuel pump is running, I'm guessing the fuel pump is not the issue.
How can I determine whether the issue is the main relay under the dash or the ECU unit? or maybe there is some other issue?
Also, in the link to the helpful post that I noted above, it indicates that fuse 24 and fuse 31 should be checked.
Does anyone know what these fuses are and where they are located? The fuses under the dash only go up to fuse 27, and fuse 24 is for the electric window. Also, I don't find a fuse 24 or 31 under the hood.
Thanks for your help

Next, with the main relay in place:
- Turned key to ON(II).
- Grounded the A7 and then A8 terminal (Grn/Yel wire) individually to the metal frame under the dash.
When I grounded A8, I could hear the fuel pump.
