Okay, So I have a 1998 Civic Coupe DX its a OBD2(A). I blew the stock motor about 8 months ago and the car has been sitting until about 4 months ago when i towed it to my house to begin pulling out the blown motor. I Recently Purchased a 2000 JDM GSR OBD2(B) motor from H motors. I tossed my civic engine harness and used the new GSR engine harness, I took the new Harness and ECU(P72)OBD2B to a local Shop to Get the harness w/ecu wired to fit my car. Now i swapped the motor into my civic , got all the mounts in good , Harness plugs up to the ecu just fine, And everything i need for the car to be running and start is installed. The car turns over but does not start. It cranks and sounds perfectly fine , perfect timing i checked. If i spray starter fluid in the throttlebody it starts up and sounds like it wants to keep going for about 5 seconeds and then stops. I feel like its so close. Ive checked all my grounds, fluids, starter,battery,ecu.dizzy,fuelrail plug order, spark plug wires,and my fuses. the one thing i noticed is that **some jdm motors or all of them dont use Vtec oil pressure sensor switches? Little green outlet than goes under the solinoid. My motor was sent to me with no outlet just a hole under the solinoid with no threads to bolt anything in there, however there is a plug on my harness labeled Vtec oil pressure switch that is green that isnt plugged in because there is no place for it to go, that wire also has a small ground coming off of it that connects to the solinoid? im not sure what to do about that. Ive heard you have to wire the solinoid and Pressure switch together since the motor doesnt use pressure switches. Also ive noticed that there is one other plug that doesnt plug in. Its black and comes off right before the 4 Fuel injector plugs. There is no where for it to plug into and im not sure what the plug is called. possibly Crank position sensor? Ill upload pictures soon i just really need help ANY INFO on necessary things needed to be done for a JDM GSR into a 1998 CIVIC DX with the wiring done and i replaced the Dizzy, Cap and Rotor, and Coil. thankyou!
