obd1 to obd2a conversion. engine won't start

[ucme]

Hey guys

i finished my conversion putting a b18c into my eg. Im using a jumper harness to use my factory obd1 chassis loom with the obd2a ecu. I have wired up the knock sensor and extra 3 wires for the o2 straight into the correct locations in the jumper harness but the engine won't start.

It starts when i plug in the obd1 ecu but with engine light on. Cranks with obd2 ecu but won't start. I've checked for codes and i just get code 0 for ecu. Tripple checked all the wires i to the jumper harness itself and everything is in the right position.
Anyone have any ideas?

Crank no start could me no fuel going to the cylinders or no spark(if electronic)

But its starts with obd1 ecu fine. And jumper harness wires for the ecu swap are all fine also

Have you remove the immobliser?

[ECU-MAN]

the immo is his problem

Use the search function. ECU-MAN has kindly made a thread of how to remove the immobliser

If your not electrically minded, simply send it to ecu man

Yeah it was the immo. Ecu man kindly helped me again. I was lucky i figured out how to solder quickly lol.

Thanks again guys
