No start 1990 740 GL repeat. 700

Hate to bother you guys again but;
Pulled the error codes.
Ignition :none.
Fuel injection: Signal missing from cold start valve- Idle valve closed- no signal from speedometer.

The speedometer and idle valve are working OK.
Any suggestions where to go from here? I switched the Radio relais with the other one on the tower.
I have spark (5 mm in open air). Fuelpressure more than 30 PSI tested recently. New plugs, wires, rotor, crankshaft sensor. Was planning on pulling the intake manifold to get to the sensors and coldstart injector. Good idea??
