Yeah I got a 00 civic ex and it's not starting. I checked spark and fuel. And it gets both. It randomly turned off one day when j was reversing and wouldn't turn back on unless I gassed it. Anyway, the harness was spliced so I replaced that. Replaced the chassis harness to ecu on obd2b also. Still doing the same thing!

 

Have you checked the mechanical timing?

 

Compression was 170/180/170/180

 

As far as timing belt yes I have.

 

What color is spark at the plugs? Will the engine start with starter fluid?

 

Spark was a spark. I'm colorblind. Injectors aren't spraying anymore, replacing them now

 

Make sure the injectors are getting power.

 

Thy are not. NeW harness is wired for resistor box. I'm taking it off tomorrow.

 

Test the main relay.

 

I'm pretty sure it's because the harness is wired for a resistor box and I'm using saturated injectors. I'll see for sure when resistor box is unaided
