i have a 96 civic hatch with a B20 swap running a obd1 P75 ecu. As soon as i turn the key on the car throws a check engine light. Its just a solid check engine light and no code when i try to find out. In order to start the car i have to take the ECU fuse out (fuse #44) and put it back in. As soon as i do this the car starts until i shut it down and then i have to repeat the process again. Im really bummed about the problem and i am guessing it could be my main relay but..does anyone have any insight on the problem? The car does not blow the fuse and also when i shut the car down the IACV valve keeps making a humming noise Until i proceed to remove the fuse and put it back in. The car also bogs in the lower RPM sometimes, until i give it more throttle and then it jumps back up.

All help is appreciated
