It's not going to fill oil cause the oil pump is not running.Just looking for a little detail on the injector precycle. What exactly is going on during this and why does it need to?
Is the valve cycling to fill with oil or is it cycling fuel into the cylinders for an easier start?
You do not have an inductive heat strategy then. I rolled back my ficm strategy to the original no-heat and this is what it does too. The latest calibration will rattle those injectors for 4-6 seconds on a cold start.I've noticed mine generally stop cycling before the glow plug light turns off.
I've got the mild inductive strategy, not the full-bore one. My FICM has the Atlas 40 tune which includes the mild inductive strategy and I also run the SRL Extreme SCT Tune. Truck starts perfect in the cold without being plugged in, maybe cranks for about 3 seconds and fires right up with minimal diesel knock. I would say that it usually lasts about the cycle of the glow plug light which is generally 4-5 seconds for me.You should let the cycle finish. The latest FICM calibration will start cycling them slowly then gradually build up speed to warm up the little bit of oil that is still remaining in the spool valve.
The glow plugs still remain on for a little while after the wait to start light goes out, you are not hurting anything by waiting for the injector pre-cycle to finish.
The real inductive heat occurs after the engine is running. I am not 100% sure on what happens here either
