My son has an 89 Civic wagon b17 YS1 swap.
it has run fine for 6 years and driven occasionally, it's his second car.
One day it just would not start, it would crank but no start.
So far we have checked wiring including grounds.
Replaced
ECU
Distributor
Main relay
Any more ideas? this just isn't normal to start one day and nothing the next.
The only other thing we have done recently is replace fuel tank, but drove it several days in a row afterwards.
When you say "checked wiring", do you mean checking continuity? checking for power where its supposed to be and ground where its supposed to be? or what?
Does the fuel pump prime? Does it crank? Spark? Fuel?

It has almost a full tank and getting fuel to the rail.

That is correct.
It does crank just does not seem to be getting spark.
Clarification
by checking wiring , yes multimeter was involved, grounds were all checked and cleaned.
Basically it ran one day as it has for 6 years the next day no start.
Does the GSR B17 have a crank sensor , I put a timing belt on a few months ago and don't remember seeing one near crank pulley although it's possible I just wasn't paying attention.
BTW I've worked on Euro cars for years and I'm stumped.
Is it getting good spark as well? If you have fuel and spark it should start unless timing is off..
Timing is fine put a belt on a few months ago and have been driving it off and on , it does not seem to be getting fire too plug wires.
Towed it to a buddies shop who has more time to fool with it.
Does the main relay control spark as well as fuel, I have two but it's a possibility both are bad , I don't think so but stranger things have happened.
Yes. Below is a drawing from bkhondaparts.com. The ignitor is part #10. The coil is part #15.
Below is a photo of the bottom of a 1991 Civic LX's distributor housing. The rotor is at the top. The connection to the camshaft is at the bottom. On the right side, about mid-body, are two of the screws that hold the igniter in place.
If you look up the part number at bkhondaparts.com, and then google on the part number, photos will come up to help you identify the part on your Civic.
In my opinion, best practice is to replace both the ignitor and coil at the same time. A worn down igniter wears down the coil faster, and vice versa. If these parts have never been changed, they're due, even if they do not fix the problem. (On older vehicles, I am in the camp that thinks some 'throwing parts at the problem' is appropriate.)

thank you..
I'm assuming the 93 Acura GSR dist is the same.
We have thrown an ECU and dist at it already but both are used.
Oh right. You have a swap. Yes, the igniter should have come with the Acura Integra distributor you installed. Did you buy an OEM distributor or aftermarket distributor? If aftermarket, consider testing the igniter anyway.
The ignition coil remains a candidate for the cause of the no spark.

Distributor and ECU were both used.
I learned years ago not to buy aftermarket parts.

Reason: Addition
have you checked to make sure the screw that holds the rotor in place in still there? Also make sure the spring that connects the coil to the cap is still in good condition/present.

I have not, but it has been in my buddies shop for two weeks and last week he was on vacation.
I'm riding by there today and will check.
I have a feeling the used distributor is bad or something in the distributor.
Also going to check the ignition switch.
I really wish there was a dedicated Honda tech near me ( besides the dealer)
The nightmare continues

Lots of sites discuss how to test the ignitor. E.g. https://easyautodiagnostics.com/hond...system-tests-1
