My car is running 70km per tank,and I'm having a very hard engine starting only @ morning

when ever the gas is applied a scraping noise is heard.. the transmission shifts smoothly
is this the differential and is it located on the inside of the transmission or can it be reached without dropping the transmission?

replace third belt from front of engine

Where is the fuel pump relay located?

When i turn on the car it sounds like wram wram

When I turn the wheel to the right or left there is a horrible clunking sound and the wheel jerks. What might this be?
