K24A2 in EF, no injector pulse
Posted: Tue Apr 09, 2019 2:02 am
Hi,
I'm finishing a K24A2 swap into an 89 EF hatch. 06 Element wiring harness, PZD ECM, KTuner in ECU installation from a dealer.
The issue we have now is there is never any injector pulse, no matter what we do. Here are some of what we have done and checked:
-Added additional grounds, even from G101 direct to the head and chassis.
-Confirmed there is power and ground to every single sensor, injector, and coil
-Run the injectors with straight 12V power and fuel and confirmed they are operational
-The motor will chug a bit with starter fluid, so it has spark
-Replaced crank position sensor, confirmed the crank trigger is in place.
I've tried the tune from my dealer and an 03-05 Accord MT base tune as I have a cable throttle body. Neither make a difference. I've confirmed the "disable immobilizer" is checked on both, removed EVAP, etc. None of it matters.
Of note, the tune I have on the ECU from the dealer has no values in any of the tables (fuel, spark, cranking fuel) and no values in the 2d map, but does show a 3D map with values, which looks similar in profile to the Accord maps, which do show values in the table and 2D map.
I'm leaving for a race weekend in 3 days, my team is all paid and we need to get this going but I'm out of ideas and open to any suggestions.
