12v71ti no start

Okay so i’m sitting on anchor. She fired up, I pulled out of the marina and my starboard motor stalled.. weird. Dropped anchor and am trying to get her going

Racors look good but changed them anyways. Feels to me like a fuel issue...? Where is the secondary fuel filter located and i’m not so much as getting it to pop... anything else you guys can think of? Yes there are several hundred gallons onboard

So definitely not getting fuel. What sensors will cause her not to allow fuel? Racors are clean and full

Fuel cut off solenoid is operating properly. In the open position and cut it and it closes compared it to other motor and doing exact same.

Check wiring? You may have a loose wire that is causing the engine to not start.

Did it stall quick or putter out slowly? If the latter it's fuel related. If the former, it's something electrical because it was running then it quit(which means you were getting perfect fuel, air, and compression adequately)

I would look over all of your wiring firstly.

Edit: I just saw your second post about not getting fuel. I would bleed your injectors and see if your getting air bubbles. You may have a leak in the fuel lines.

Do your engines have the shutdown flapper on the roots blower? The little latching cam lever? I’ve had those rattle closed before.

Is the fuel pump working? If you crack the out put line on the pump and crank engine does fuel come out?

The fuel filter is located between the fuel pump and the fuel inlet manifold. It usually consist of a fuel strainer and fuel filter. They can be cartridge or spin on depending on the model and year built. Detroit 2 cycles don't need bleeding like injector pump engines. When the fuel pump is operating the fuel flows continuously thru the filters to the head rails and thru each injector. Fuel pressure to the inlet manifold should be 50-70 pounds.
The engine has an automatic shut-down system. It protects the engine against the loss of coolant, overheating of coolant, loss of oil pressure or overspeed.
If the oil pressure goes below 27 psi, coolant loss, or coolant above 203°F the auto shutdown will activate.
There is an air shutdown valve on the top of the engine, above the blower, that has to be reset if the auto shutdown sequence has operated.
If the engine is in good condition, it sounds like an air leak in the fuel lines to me.
On my Detroits, I added an inline 12v electric fuel pump to aid in changing fuel filters and to flush out air. I could use them in the event of a fuel pump failure. But DD fuel pumps rarely fail suddenly.
