I was working on my car the other day and left a wrench on the valve cover. The wrench worked its way down and fell onto the battery and shorted and then immediately fell down under the car. After the short my main relay has been clicking very rapidly and I cannot start my car. I have tested the main relay and checked visiually and it seems to be fine. In addition to the main relay when i turn the key the ECU light comes on very dimly and blinks rapidly with the main relay.

In addition to testing the Main relay I checked it for any dry joints or other problems. I also Sanded/cleaned all my engine grounds including the Thermostat grounds. I also checked the main fuses in the engine fuse box visually and tested them for continuity. Any fuses that looked even a bit suspect were changed out as well.

I am at a loss right now as to what this could be any help would be great.

 

cheek the chassy gronds and the mane relay its self ther is a paer of black wiers going into it stick a test light in that terminel with the relay pluged in turn the key to start and see if it dimly lights that grond has bin non to go bad and if it duz light that means that grond is bad you can add a new grond or fix the old one and is the bat still good?

 

Um... The battery is good (12.93V). Can you please clarify what you said. I didnt really catch that?

 

cheek the body grounds and then go to the main relay and see it the main relay has a good ground i have fond befor that the grounds going to it can calls the same problum its 2 black wiers that go to the same terminel hoke a test light to ground and stick the prob into to that that terminel and try to crank the car see if it dimly lights or starts if it lights or starts just fix that ground.

 

I jumped that terminal and the problem went away. Any Idea where these grounds actually go to? I have already checked the grounds at the thermostat houseing and the battery, transmission, and valve cover grounds.
