Rough running, No Idle, Very fuel Rich, ECT? FPR? 700

Hi,

Just picked up this car.
1989/90 740 GLE - Has a B234F in it.

Getting too much fuel. Throttle body is wet, plugs are wet.
Sounds like it is firing on 3 cyl, though i have checked that.
Fuel smoke. Rough running seems to be throughout the RPM range.

Been reading through the FAQ's

Just a bit lost on what i should try first.
The ECT or the FPR.

Thanks in advance
