1992 Honda Civic eng won't start 1992 Civic

Thanks for reply, this is what i;ve done I have checked the main relay its ok, I replaced the fuel pump.I;m getting fuel at the fuel rail, how can tell if the injector are firing?

I have no voltage at injector plugs.

All fuses and relays ok how do I check the ingition switch, and where are the ckp and the cas sensors located what do they look like?

OK this is what I have done so far check main relay getting three clicks, fuel pump runs, starter engages, I have replaced coil, ignitor, ful pump, distributor housing, and iignition switch, replaced the emc with use one, but when I connected the ground cable it gave off a little spark, don't know what cause this right i'm stuck don't know if it 's in the engine wiring debating if I should change the engine harness, thanks.

Something else I notice was that the ground wires on the thermostat housing, I have 4, two blk, and 2 more, one of my blk one gose to the temp. Switch.I've looked on other 92's they have 4 wires the same but all 4 and the temp switch has its on two, is there something wrong with my harness?

Try having someone crank the engine over while you test the injector for voltage. If it has intermintant voltage it is a fuel pressure issue. If it has a return line try pinching it off or blocking it. If that works its a fuel pressure regulator.
