Hello there,

I have a problem with my b18c civic eg6 swap.
the engine was dropped in about 2 months ago everything was okay.Btw i replaced the fuel pump about a week ago.
i went a 3 hours road trip with the car and when i came back home the fuel lamp on the dash came on and the fuel pump sound a little different. The next day i drive to the petrol station to put fuel ,i came back home and after about an hour the car didnt start, it cranks but not start.
the power windows , sunroof, fuel pump is not working , the check engine and oil pressure indicator on dash are not working as well , looks like the dont have conection to the ecu.
radio , lights and gauges are working.
All fuses are okay ,also i replaced the main relay.
i checked with the multimeter and positive pole of the battery shorts with ground .
is a wiring problem but is anyone in here had something similar to help me out what to check first
sorry for my english btw

 

Key switch - electrical portion. If you turn the key on and nothing on the dash powers up, then power is not being distributed to the ECU. No power to the ECU means no fuel pump function. If all fuses are good, both under hood and under dash, then you should test the electrical output of the key switch.

 

Thank you man and sorry for the late reply! I replace the key switch and the problem is solved!! Thank you again i really appreciate that.
