Recently have been having a random fuel pressure issue at start up after the truck has been sitting overnight. The engine will take about 7-8 seconds of turning over before it cranks up, once it starts it running normal. The Ford app sends me a notification stating the “fuel control system is having trouble achieving the required fuel pressure to start the vehicle” but it doesn’t give a check engine light. It does not do this every morning, for the past few months it’s only done it a handful of times until this week. Happened twice this week. Any ideas? There was another member of the forum that was getting the same notification from the Ford app, but I am unable to find that thread again. Paging @FordTechOne

Do you have ForScan? You would need to retrieve DTCs to get a better idea of which system is affected (high or low) and the fault that is occurring.

I’ve never used ForScan. I will download it this evening and see what I can find out. If you had to guess, what would you guess is causing the issue?

There are a lot of possibilities, but with the extended crank before starting, it sounds like the fuel pump check valve may be allowing fuel to drain back from the lines.

You’ll need a compatible adapter for ForScan as well, they list them on their website.

I was able to pull the DTCs and it came up with “P1035 - Cylinder 3 fuel injector heater circuit high”. Any ideas?

Interesting; that is not a valid DTC, as these trucks don’t have fuel injector heaters. Has the truck been tuned?

How did you pull the DTC? Forscan should give you the description. I show P1035 could also be something with the crankshaft position sensor

I have an OBD2 scanner that also reads DTC’s - albeit somewhat questionably it seems.

Two new codes today. Idling at a light in traffic the engine dropped to 400-500rpm but didn’t die. Went into limp mode.
