this is what i have so far:
car: 89 civic si hatch,
motor: d15b,
engin harness: obdo,
ecu: obdo ls
distributor: 95 si

im wondering which one matters the most, my engine harness or my ecu harness that wont get my car to start?
 
your engine harness is your ecu harness your ecu tells your engine what to do in order to start
whats your problem ? what are you trying to do ?
 
i'm having difficulty starting my car i don't know what is the next step. what i done so far is convert the motor harness to obd1 and dropped the motor in, got the distributor to spark up, timed the pulley and cam, got a old skool ecu hooked up but still the car is not running. the car will crank but run.
 
why are you running a LS ecu w/ a d15b
 
the reason of this is that i have difficulty finding a cheap ecu jumper and a cheap but good vtec ecu, this is the only ecu i can affort and will plug right up
 
Of course it won't start, probably running rich. A PM6 will probably start it but no VTEC. You can always get a PW0 or PR3 ECU(they're both JDM though IIRC) and have them chipped for a D15B.
