1995 BMW 524 TD s electronic fuel injection

Electrical problem
1995 BMW 524 TD s 6 cyl Manual 160000 miles

l bought this car for £550 in england and drove it to scotland no problem, the next morning it wouldnt start. It started with a tow and ran fine stopped and started no problem then next morning same thing wouldnt start without a tow, the car has been serviced recently and the battery is in good condition. Then l noticed as l turned on the ignition that a electronic fuel system symbol flickered on the dash just for a second then went out. Can you help its in great condition for its age and been well looked after, its actually a 525 td but options on ask a car repair question dont show this model
