What's up HT" I have a 94 civic hatch swapped to the b18b1 had a problem with cylinder one "closest to timing belt" not firing thinking it was the injectors ordered new ones still had the same problem so I changed : fuel rail cap and rotor coil pack new distributor fuel filter spark plugs plug wires added extra ground wires then I started thinking wiring" so checked and no blown fuses or relays so i ordered a new engine harness. No luck so I went a step further and got a "running" 94 civic ex and swapped the firewall harness still had problems so I bought a b20z thinking maybe mechanical issues and now the b20 is not firing on the same cylinder" please help I'm stumped I've practically swapped everything so any input will be appreciated thanks"....

 

ECU?

 

Hey whats up Frankenstein its gotta be something simple you already replaced almost everything maybe replacing the harness at the ecu would be a good part to throw at it next or maybe the ecu has something internally faulty good luck and by the way welcome to HT"...

 

Thanks for the ideas nothing yet, tried 2p75's the stock crv ecu and a chipped p06 for an ls...also finished the harness swap now every wire from the headlights to tail lights have been replaced and put new gas in and the problem is still the same" missing on cyl 1 with spark and fuel oh also blew out the fuel lines with compressed air as well as the rail"

 

Compression test time

 

Check your timing it might not be correct
