ok 2 weeks ago i parked my car to work for the day, that night go back and car won't start.
Finally got car back to my shop. I am completely lost.
It floods itself out, i unplugged injectors it would start and run for a second, plug them back in and flooded, got new plugs same ****. Have spark at every plug.
so put in a stock p28 ecu got car to start and ran rough, smoking black like crazy wideband showing all the way lean (AEM). pull off a plug wire one at a time and none really made a difference :S
put tuned ecu back in and wouldn't start at all, flood right away. Got another socket ecu today and now it wont start at all, even when unplugged the injectors.
so tonite i
changed plugs, wires, ecu's, chips, injectors to stock, coil, distributor. checked every fuse in car. used noid light on injector clips and they all pulsed. checked timing was all lined up still
I don't know what else to do :S

the car is a 96 civic, converted to obd1 like a year ago.
b20/vtec
s2000 injectors
tuned by jeff evans 3 weeks ago, ran great for 3 days before this happened

someone give ideas PLEASE
