Hi everyone. I have a Honda Civic, 2006. A mechanic I know tried to help me by jumpering the low/high pressure switch (located on the line just to the left of the compressor) to test the air conditioning compressor...the car didn't like it and shut off.

What he did was unplug that connection, and then hooked the battery up to it. Now it won't start. Fuses have all been checked, and are intact. It's not producing a spark. Diagnostic computers will not connect to the car.

Does anyone have any suggestions? Thank you very much for your help.

 

seems like the ecu was possibly damaged but you have to be sure all fuses are still good by using a multimeter to check for continuity

 

there are also some inside the cabin
