ok my car starts with a obd-0 ecu with my obd2 dizzy.
when we put the obd-1 ecu via rywire jumper harness injectors won't pulse. we used a noid light to test it. pretty sure getting spark because when we put starting fluid in it starts but dies afterward.

so car starts with obd-0 ecu but not with obd-1 ecu. we tried 3 different obd-1 ecu and still won't start. all ecu's are fine and working.

btw its a ls/v motor. in a ef hatch. please help me this is bugging me and want to get my car running. wired and soldered the obd-2 dizzy using the boomslang wire diagram.

 

you need obd1 injectors and you also need to get rid of the resistor pack if your gonna be running a obd1 ecu. you can burn up the injector driver in the ecu if you use the wrong impedence injectors.

 

injectors are already obd-1 and resistor box is removed. i don't think that it matters about the injectors and the ecu have to match as long as the dizzy and the ecu. because i have running obd-0 injectors with resistor box for more that 2 years with and obd1 ecu and obd1 dizzy on my other car and its been working fine.

 

nvm i got the car running swapped 4 wires on the rywire harness. and fired right up.

 

what 4 wires did you swap?
