I recently swapped a jdm b16a sir ii into my 95 del sol si. Everything went well with the swap until I ran it. At that point I only had one cylinder firing. I changed spark plugs and that cleared up 3 of them but i cant seem to get the one closest to the distributor to fire. Its getting spark, has compression, but the injector will not fire. Ive checked the reistance at the plug and it checks out ok. Ive switched injectors with a working cylinder and still nothing. Its got a p30 ecu and isnt throwing any codes. Any help would be great. Thanks

you check all your grounds? Cheack the one on the thermostat housing. if thats not grounded and the intectors are getting power they still wont fire.

Well I checked the ground and it was fine. I tried a noid light on the injector plug and the light stayed dim constantly. I tried it on another injector plug and It lit bright and flashed. I'm getting really frustrated with this crap. I want to drive it already!

that is weird? you try swaping the ecu?

Thats the only thing i haven't tried yet. Its not throwing any codes but still. Any idea if any other ecus would work or does it have to be a p30

just throw one in there even a stock P06 will fire it up. but I wouldnt drive on it. I had a simalr problem when i did mt h22 swap and it was bad ECu good luck bro.
