Ok I've just completed a b18b1 swap out of a 94 integra in my 99 acura el (in other words civic) which comes with a d16y8.

I wanted to run the car obd1 on the factory integra ecu, im using a boomslang obd2b to obd1 conversion harness. But the ecu literally does nothing. The fuel pump doesnt prime, I dont have spark. Nothing.

Oddly enough though it starts right up with the factory d16y8 ecu, although it doesnt run great.

Is it possible the b18b1 ecu I have is fried? or is there something else im overlooking?

 

Had the same problem with my integra that i put a b20 into. I put a obd1 p75 with a obd2 to obd1 jumper harness in and had no fuel. Swapped back the obd2 ecu and started right up. Alot of people use a p28 chipped to run their swap. I say its the computer. But if anyone knows if the obd1 p75 ecus run everything but the fuel pump let me know. I put a p28 in it today and it fired right up. So either the p75 was no good or they dnt trigger the fuel pump

 

Im also quite sure I have no spark. Anybody have any idea's
