My bmw 325i 2002 seems to have the exact problem. There is no voltage when cranking at the fuel
pump ONLY WHEN THE ENGINE SITS OVERNIGHT IN COLD WEATHER. Once the sun hits the
car for a while (the ambient temperature rises) The engine starts fine.

There is no voltage at the fuel pump when engine cold. swapped the fuel pump relay, main relay and cranshaft sensor from another same vehicle and still engine does
not start.

I will really appreciate your help.

Thanks,

Jess
im having the same issue, my car is at a very reputable bmw mechanic so im hoping he fixes it. have you had any luck?? i found that if i warm up the ecu with a heat gun the fuel pumps clicks right on and the car starts fine. so lets hope he figures out why that is soon.
