Hey everyone.
I just installed a b16a in my 1990 crx si. I am runing it obd0 and using the hasport v-tec harness. The car will not start or sputter at all. I was getting weak spark so I replace the dizzy, I have good spark, have fuel, compression, the main relay works. I sparyed started fluid down the throttle body and when I cranked the motor over it did not even sputter. I have tried adjusting the timeing by moving the distiburor around but it has done nothing. When I turn the ignition to "ON" The ECU flashes the one ready light once. I do have the right firing order also.
I was told the engine will start without the v-tec hooked up. I have 2 wires I still need to hook up from the hasport harness. They go into b5 and b19 at the ecu(v-tec oil pressure and the knock sensor). I have the honda pin removel tool but I canot get the original pins out of the ecu harness. Could these two wires be causeing the no start? I thought they only are for v-tec. What else can I check?
Thanks for the help.

 

Neither of those wires being left in will cause the problem. However, putting wires in the wrong locations might.

Also, you ARE using your stock 1990 CRX Si engine harness, correct?

 

Is your main harness ground hooked up. Im talking about the one by the thermostat housing. I had the same problem with my first swap a long time ago. Sometimes it will pull back into the harness. Goodluck

 

it sounds like your not gettin any spark so check all of your grounds ill bet thats the problem

 

So it is cranking over. You have spark, you have fuel.
Check engine compression while cranking... maybe you have a bigger problem.
The locash harness wouldn't cause a no-start condition

 

Make sure you are reading the instructions correct, What codes do u have, and yes, check grounds...
