I just swapped my D15D6 out of my 90 CRX for a D16Z6 out of a 94 Del Sol. I got the OBD1 adapter harness, got it running fine and drove it home. After I start it once and shut it off, it WILL NOT start again and throws code 15 (ignition output) till I reset the ECU. I reset the ECU and it will start and run fine, I shut it off and it wont start again. The P28 was an automatic and I converted it to a manual properly from what I've seen. I've tried removing RP17 and RP18 with a jumper on RP18, and I've also tried RP17 removed with the resistor on RP18. Any way I do it, it still does the same thing. I tried an ECU somebody else had that he had modified taking just RP17 out and the car ran fine and started every time. Anybody know where my issue is?

*edit* My O2 sensor was wired incorrectly for about 3-5 miles of driving before this problem, could my ECU have been damaged?

if your car was running with the o2 wires wrong you should have thrown a CEL. but im not to familiar with the EF's and how they check there codes. But i believe your best bet would to buy a virgin P28 off someone. tampering with Ecu components that ur not familiar or unsure working with can cause problems.

or your Dizzy could be going out soon

 

What distributor are you running?

 

What is a Dizzy?

I am using the OBD1 distributer that came on the Z6.

As I said before, the motor runs fine for the 1 run before I reset the ECU and using another ECU it works flawlessly. I am avoiding buying a new ECU at all costs, but I have a feeling the problem lies in the ECU somewhere.
