Hello All,
I have a 2016 Ford Fusion EcoBoost 1.5 that Won’t Start. I’ve replaced injectors, and confirmed that coils and plugs are working. I’ve confirmed that both fuel pumps are working as well. When trying to start the engine, the fuel rail pressure gets up to around 1700 psi. I have not been able to find what this pressure should be. Can anyone here tell me? Or have any other suggestions? I did swap in a new high pressure fuel pump with no change. The only DTC I’ve see are misfires.

The issue came on rather quickly. One day it started having hard starts with a noticeable miss. This would level off rather quickly before I even started to drive No CEL. The next day I got a CEL with a misfire code, and by the end of the car wouldn’t start.

Thanks in advance for any insight!

 

Hi press fuel injection is new to some folks, but the smart thing to do is read up and learn as much as you can.

The press i believe is around 3000 psi and is controlled by the fuel control solenoid that allows certain volume of fuel to enter and get pressurized. It is a whole new animal and requires knowing more than just specs. There are DEFINITELY SAFETY considerations involved and the best suggestion I could offer is leave the work on that system to those that have the training and correct tools to do the job.
