Most diesel engines are hard to start when it is cold. Plugging the diesel engine block heater in will help the engine start.

Ether is highly combustable and is used on most turbo diesel motors. Usually used for performance on gasline turbo cars. ether can be used if the motor has a hard time starting up.
My 1991 740 volvo turbo doesnt start specially during the morning.Is it comes with a cold start valve?
glow plugs
Probably the fuel pump. Or the injectors.
yes
If you step on the pedal and have no power or it's hard to accelerate you might want to get it looked at.
the fuel pump is located between and underneath the turbo and fuel fiter housing.on top of your engine.it has a blue fuel line going to the front and a fuelline that goes to the rear of each head.it pretty hard to replace.
Hard starting on a diesel is from a lack of fuel or a lack of heat/compression. Air in the fuel lines, plugged fuel filters, and broken electric fuel pumps are the more common hard start issues. Cummins engines use a grid type air preheater. If the hard starting is ONLY in cold weather this is a good place to start.
