Hi everyone, this has been my problem more than half of year and i finally decided to ask help..
almost everytime i try to start my fuel pump is off, no crank, ecu no power. but everything in lights to climate control works! battery fine, starter works in cables, i have check the engine grounds and fuses all seems to be ok.


no power in ecu?
i have been 2 times randomly power to gauges i hear fuel pump and everything and try to start i hear just crack and then lights went off again only those three left and fuel pump don't work.

today randomly all normal power 🤨🤨
car has not run like 6months and i really need help this strange thing..

 

Test the alternator and ignition coil.

Also your main relay may be faulty.

 

i have change main relay without results, i just know my ecu don't get any power some reason, ignition switch get power 🤔 i have 2 ecus tested and now plugged hondata s300 so i know when ecu is running.. is there between switch and ecu someting what does this what i need to check? 😪
