Picked up a 90 integra gs as a shell. Bought a b18b1 obd2, picked up intake manifold, throttlebody, distributor and threw them on. Wired the obd2 injector clip to the da wiring harness. Noticed the prior owner was running obd1 because the resistor box was missing. So I wired it in. Also the car was given to me with a pm5 ecu.

My check engine light is staying on. Normally it is suppose to turn off after 2 seconds. I verified the grounds for the ecu on the A clip. Having trouble figuring out which are power if someone could steer me in the right direction.

Will the pm5 even work for this car? Im pretty sure thats for a 88-91 civic dx which is dpfi....

I am not getting power to the fuel pump and my main relay is getting power but doesnt click when I turn the key

Pump kicks on when I jump it

No power to tps or map when key is on if I unplug the driver clip I get 2volts

any help greatly appreciated
