So, I pu a D16Z6 in my 91 hatch, I have an OBD1 Ecu, home-made jumper harness. I'm not hearing the fuel pump kick on and I'm getting no Spark when I crank. What I know: I checked power to the distributor, I have 12volts on the Two wire plug. The fuel pump worked before I removed the old ECU (PM6) What I'm considering: The fuel pump may have gone bad from sitting so long. or the relay. I need to look and see which relay it is. 2: I need to re-check this jumper harness... 3: a common problem is getting some crank sensor wired crossed when switching dizzy plugs; I'll have to check that. Is there a polarity to these sensors? I noticed on the obd1 pinout one is power and one is signal, but on the OBD0 pinout it doesn't specify polarity to match it up. 3: there are two sensors on the back of the mainifold with the exact same plug. I need to know what these are and make sure they're in the right place. One has been extended... ANY suggestions will be considered. If it sounds obvious, that doesn't mean I havn't missed it. I'm busy as hell with work on only see this car for 1 or 2 hours a week.
