Hello I used an noid light and have no power in all 6 injectors.
I have crank and replaced crank position sensor and replaced ignition relay.
I'm assuming all that's left to do is replace ignition harness. Unless I'm missing fuse? Jbe box fuses all good.

I assume you have read use a BMW specific scan tool to read the codes in the DME? That could tell you a billion things you haven't covered in your post.

Please provide Last-7 Characters of your VIN?
Is your 335i an E9x? Engine? Chassis?
Any DME Fault Codes Read?

Generally, there SHOULD be 12V+ to the White wire of each injector whenever Ignition is ON. The Ground signal, which varies in duration depending upon fuel demands, only occurs when the engine is cranked or runs, & DME is powered & receives Timing Signals from Crankshaft Sensor & Camshaft Position Sensors.

So fact that Noid light doesn't flash is NOT helpful except to show that you are lacking EITHER (1) B+ at White wire with Ignition ON, OR (2) Ground signal from DME during Cranking. I would suggest starting with Voltage at White (SOLID White) wires with Ignition on, testing with Multimeter, & then providing those results & Info requested above.
