Starting problem, new dist, no spark?

Starting problem, new dist, no spark?
Hey guys, I posted this on the civic wagon forums, because this car is indeed a 91, civic station wagon (4d).
It's not an AWD, it's Fwd if it matters. 1.5 liters.
Last night, I was driving home, took a right hand turn and the wagon just shut off. Wouldn't start back up.
It has over half a tank of gas.
Engine rolls over fine.
Tried jumping and push starting anyway.
I turn the key on (not starting position, just on), and I hear a -click-, supposed to right?
No fuses out. Not even the 80 amp.
I did some research, and it's common that the "main relay" goes out in these cars. BUT, someone said they don't believe the main relay would be the cause of -no spark-.
Here's the old distributor, see that piece completely toasted?
That's what gave me my initial motive to replace it... Still no go.
new dist, cap, rotor, etc.

Does the distributor rotor rotate when you crank the engine? Sudden death on the road is often due to a stripped timing belt.
The Main Relay only controls the fuel, not spark.
When you turn the key on but don't try to start, the CHECK ENGINE light should come on for 2 seconds then go out. You will hear two clicks from the main relay one when it comes on and one when it goes out. You should also hear the fuel pump run and then stop. Also pull the brake handle up and make sure the BRAKE light on the dash stays on while you're trying to start. That shows the ignition circuit has power.

If the fuel pump does not prime AND there is no spark, then it could be a bad main relay, a blown main relay fuse or ECU fuse, or a bad ground connection on the thermostat housing.
If you only lack spark, check the timing belt and the coil and igniter unit in the distributor.

I'm having the same problem, it wont start but if i push and pop the clutch it starts right up, this is my first honda so i know nothing about them, any ideas? I alredy tried turning the switch on without starting and my engine light does come on and turn off after 2 seconds and my hand brake light does stay on

Also should I try resetting the ECU?
Hey also, I found this...

It in the diagram, it shows the main relay running wires to the ECU several times. Then doesn't the ECU govern whether the car gets a spark or not?
-Just asking, I really don't have a clue.

Well. The dist. Came with all new internals too. Its all new.
We got a new main relay today. It did no good.
Also, the dist spins and so the timing belt isn't jacked either. Like, we left the casing off and watched it.
We checked for spark at the wires actually. Just won't happen.
We checked fuses, the ecu fuse is the hazard fuse right?
All fuses seemed fine either way.
Ill check the thermostat ground... See where that goes.
