Hey hondata people,
I need help figuring out why my EP3 will crank but won't run. History the car ran fine and I parked in the garage and the next day it would just crank and not start. Attached is a log I made of me trying to crank the car a few times, was wondering if anyone might spot something wrong.
Self Diagnostics:
I've checked every pin in the ecu manually and haven't seen anything wrong as far as voltage and have load tested the main and fuel relay for voltages and they are operating correctly with proper voltage when engaged. I've replaced the following sensors/parts with new oem Honda parts: crank, cam, map, TPS(calibrated), and ELD. I can hear the pump turn on when someone puts the key into on position, so I'm assuming the pump is working. I pulled the fuel pump fuse and attempted to do a spark test, but did not see any sparks which leads me to believe it was some sort of ignition issue.
My guess:
I think it's something related to the immobilizer, but I do have it turned off in kpro. Also noticed the green key light never turns on. Could a damaged immobilizer prevent a car from starting while its disabled?
kmanager: 4.4.3 kpro: v4 (white board) ecu: 37820-pnf-a03
Thanks,
Dimitri

Post the calibration you have uploaded to the ECU.

Thanks for replying quickly but I ended up fixing it.
After replacing all those sensors (which I believe the MAP sensor and bad ground was the original issue) and removing my fuel pump a couple times when I was inspecting everything I must have loosened a wire on the fuel pump housing and it was preventing the fuel pump from running. I unplugged the fuel line to the rail and realized it was no longer pumping gas, so I took it apart and got the fuel pump to work again.
After a few starts the car was idling perfect. The hype is real! I'm just glad to get this bad boy back on the road.
