Well, when you were cranking the engine over did you have the throttle fully
depressed? you will not get any fuel during crank out of the injectors if
you dont have the plate lifting. Either that or the fuelmixture is way off.

Ok well it looks like you should check the Bentley manual for your wiring
hookup. The - side of the coil is not to be connected to ground. it is to be
connected to the ignition control unit via the green wire. the Hall sender
is connected to the ignition control unit. NOT the coil directly.

Cold start valve is have one terminal connected to the 50 side of the
starter. I dont remember which side ot the thermotime switch is to have this
also. then there should be a wire going to the cold start valve from the
other side of the thermotime switch.
