M50 non-vanos, Just put a new head on. Hooked everything up. It will turn over but there is no fuel getting to the cylinders, the throttle body does not move at all when I go to turn it over, and I do not smell fuel after attempting to check. Any help would be greatly appreciated
No fuel.

throttle body doesnt move automatically. Thats the Idle control Valve's job.
Do you hear the fuel pump when you turn the key?
Fuel rail hooked up properly? In is at the front of the rail, return at the rear by the firewall?
Camshaft and crankshaft sensors hooked up/not reversed? -

it will still fire with a bad ICV..just will have a really rough idle. ICV controls air, not fuel.
Do you have spark?
So you dont hear the fuel pump?Comment

all the grounds and power leads connected properly at the firewall on the passenger side?Comment

Which engine management? The NV M50?
Sparking and Fueling is dependent on Crank Signal. Then the fuel pump is turned on by the ECU when its senses cranking..Past Car : E30 S50 6 Speed 5 Lug 3.73
Current : Z3 S50 OBD2 (Smog Legal) 6 Speed BBS RN Dual Ear Diff

There should be main harness underneath your intake. On the later VM50 the CPS and CAMPS have reversed connectors. This engine harness goes back to your ECU.
You will need a pin-out diagram for your engine management to check your CPS. Wedophones.com has the diagram (In a cryptic location).
If its a VR sensor you can read for MV while cranking by back probing the ECU Connector.Past Car : E30 S50 6 Speed 5 Lug 3.73
