Have a 91 DX Wagon which I recently swapped the stock D15B2 for a used ZC that had been in a wrecked 91 CRX Si. Modified stock harness and took what was needed out of CRX (e.g., injector resistor, ECU, etc.) and put them in DX. Put in new timing belt, clutch, fuel pump, fuel filter, etc. as part of swap. Swap went great and the engine ran splendidly in the DX. After 40 miles, the car was driven one day, parked, and wouldn't start later. After cranking on it the ECU would blink once for ECU on and then repeat through 20 short blinks followed by a pause and then 20 short blinks (over and over). Then found car would run if 1/4+ throttle was applied on startup. Engine will run rough and will not idle. No backfire. Note: after getting engine to start and at least run, the ECU on next check (ignition on but not cranking starter) blinks once for power on and does not blink at all afterward. Found that everytime it is cranked but does not start the ECU will do the 20 blink thing. If you actually get engine to run, it doesn't. Initially thought timing belt jumped but that was not it. Checked for spark.. Found plugs worn and #4 fouled. Replaced plugs. Engine will start with throttle applied and seems to start easier but still very rough and no idle (just dies). Moved to distributor. Have components from D15B2 distributor (which had been replaced in 97) and swapped out rotor, coil, upper pickup, and chip (hitachi I think - not sure what it does). No appreciable change in running. Did not swap out lower pickup because I couldn't get the pin out of upper pickup rotor to remove plate to get at it. Also note that when plugs are pulled, they are a little wet and definitely smell of gas. This is what led me to think distributor and ignition issue. Could this be a distributor issue where I need to just by a new one? I didn't replace distributor cap because it looks fine. Could this be clogged injectors? TPS or CPS? Any suggestions would be greatly appreciated.
