Default D Series into Integra

Hello all,

I'm in the process of building a race car. I bought an Integra shell for my B18B1 swap and since I’ll have a perfectly good integra shell sitting around and a Civic motor, I decided to put the D15B7 from the Civic into the Integra. I have two friends who have done similar swaps (OBD1 D series into Integras) and their cars are running fine. Mine, however, is not.

*****
The problem I'm having now is:

1.) When I turn the key to accessory, the fuel pump does not prime, and

2.) When I turn the key to start the car, I can hear the relay click, but the starter does not crank-- instead, the radiator fan starts.

*****
The car did this once before, but I tried starting it over the course of a couple of days and eventually it cranked over VERY slowly out of the blue.

It ran for a while, perfectly fine—mind you, and then started behaving as mentioned above.

*****
Here are some details around the swap:
  • Car is a '97 OBD2A Integra with manual transmission
  • Engine is out of a 93 Civic DX with manual transmission
  • I am using the OBD 1 ECU from the Civic with a jumper harness
  • I am using the OBD 2 engine harness and I have modified it
    • Soldered OBD1 injector clips onto it
    • Soldered OBD1 alternator clip onto it
      • https://www.hamotorsports.com/obd2-alternator-obd1-harness.html
    • Lengthened IAT sensor to fit onto Civic engine
    • OBD 1 distributor with conversion harness
Any and all help is appreciated. Thanks.

Why don't you just get another B series motor instead of using the D15? Integras are slow as **** even with a B18B1 and you're running a SOHC non-VTEC???

This is the swap inside of the car for those of you interested:



Got the car cuz it ran well and had a clean shell. I really want this thing running so I can get started on caging my Civic for next year...

^This is the reason the Honda community is going to ****.

I wish I could pitch in and help, but I'm not quite sure about the solution to your problem. Hopefully someone in here will be able to though. I just came in here to say that a car's driving characteristics go far beyond just what motor is in it. I'm sure it will be fun to throw around a track even with a SOHC in it, depending on what kind of other components you're running on your car. Good luck!

Thanks bud. Gonna try and look at potential grounding issues as a friend of mine said sporadic behavior like this can be caused by forgetting to attach one or two ground wires. Then I'll check power harness to alternator.
