93 Si, D16Z6., completely stock. It had a weird intermittent idle misfire/dying problem. As a result of chasing that problem, the car has new NGK wires, and coil, new icm, new cap and rotor, good plugs. TPS was tested, fuel pressure gauge was put on filter to check pressure, 41~psi usually. Has new injectors and ICM as well. Nothing I had done so far changed the way the car ran. Bout a week ago it just wouldn't start. Drove it somewhere, was there for a bit, and couldn't leave. Fuel pressure is still good. Checked for spark, it's good, and just put a new main relay in it 5 minutes ago, doesn't even try to fire. I feel like I can smell fuel from the exhaust. Seriously what gives here guys

 

Checked grounds too, forgot to mention, when the car was running it would start at the bump of the key.

 

check the ignition switch?

 

It's not the ECU, tried one from a running civic EX, didn't do anything. What wires can I test on the ignition switch it to see If they're good. Other pins to test as well?

 

Could the wiring harness be damaged or cut. Maybe there is a short somewhere.

 

try putting a little bit of gas into the intake hose...and i mean just a little,like enough to fill the small cap on a can of wd-40.crank it,if it starts you know its a fuel delivery problem.it will die once the fumes are gone but at least youll have an idea what could be ruled out.

 

Solved guys, swapped distributors off a friend's civic and it started right up. Must be rotor or the housing sensor.
