Ive recently changed the gearbox in my car got everything back together started it up fine twice, and I stalled while in gear testing.

After stalling my car wont start at all and doesnt even turn over, ive tested a new battery checked fuses but nothing...

Any help?

in addition there also appears to be a grinding noise when I turn the car on which is constant but when I clutch in the noise goes away - i believe this could be the release bearing though...

Car is a Honda civic with a b18cr running gears
