got a b16 obd0. I have a problem with two cylinders not firing. Ive double checked the firing pattern, I have spark to all four plugs. I could not smell fuel in the two cylinders when checking for spark. Im using my old 90 crx si harness that ran my car fine before the swap. Waht do you think I should do?

 

On the two cylinders not running check that 12V is going to the striped wire. If it has 12V then hook up a "noid light" and see if the ecu is driving the grounds correctly. If both of those check out try a new injector or try moving the injectors you have around to different cylinders and see if thew dead cylinders move with the injectors. If the dead cylinders stay put run a compression and possibly a leakdown test.

Good luck.

BTW a noid light is a LED light bulb run between the two injector clip terminals. These can be bought or made.

 

did all of the above and it came down to the old "tap-tap" test... I had my g-friend turn it over and hold an idle while on two cyl's. Tapped on the #2 injector an it fired, tapped on #3 and it fired. Had her take her foot off the gas and it idles by itself. it idles kinda low, but its workable... Thanks guys
