I have a 93 civic hatch with an h2b
It has fuel pressure
Has spark
Main relay clicks when on "on position"
When on "on position" cel stays on doesn't turn off the fuel pump primes
Checked codes it's the "iat" code 10 but I know that won't cause it to start
Has fuel cell and external fuel pump on the engine bay
Fuel pump is wired to body ground and power wire is wired to the wire that leads to the stock fuel pump wire yellow/green wire.
So it primes like stock when on position
But doesn't start it has 10.9 volts on the injector plugs
I'm clueless on what to do any help please

1) Verify that the injector ground wires properly pin to the ECU

2) Test for continuity to body ground at all ECU connector ground wires

 

What pins should I test?

 

Which injectors? Which Engine? Which Harness?

 

I had this prob with mine. Turned out 3 of the injectors were fride . Pull them out earth one of the connectors and just tap the other connector with 12v . They shoulf click. If they all click then put them back in the rail and zip tie them to the rail. Then put them in 4 bottles and crank the car. You should see fuel spraying into the bottles.
