i installed an obd0-obd1 jumper harness into my ef hatch, plugged everything in exactly how i was told to do and i have a PO6 ecu u plugged in. when i turn the key to prime the fuel pump, it pops a fuse every time. im running obd1 injectors and the distributor is obd1 as well, but im using the original engine harness with distributor jumped as well. does anyone have any ideas on what is wrong??????

 

did you remove the resistor box for the obd0 injectors?...

 

Where did you get the jumper harness?

 

Sounds like a short some where brake out the volt meter and do some testing
