Car stall when hard turn and hit curb

[papa_geza]

sorry if my engine don't fit the sub forum M42 engine, that because my engine is M40.

My problem is every hard turn and bump to the curb my engine always stall.. i identify the problem with the fuel pump but the other problem my radio unit always on by it self when the engine on by itself ( memory setting reset by it self just like when you unplug the battery )

stereo is aftermarket or factory origional? sounds like the stereo was wired up wrong. if its aftermarket, the red and yellow wires are probably switched around by mistake.
