Triton MQ stalls and doesnt start after long drives

Postby Robvenning on Mon Mar 27, 2023 9:42 pm

Hi everyone,
My 2017 Triton MQ AUT has developed a very strange symptom. After long fast drives (150km+ at 120kph) it will star the next day, very quickly stall and then it wont start until I have primed the pump on the fuel filter, then runs sluggishly for a while, then all back to normal. It's done exactly the same thing on my last 4 or 5 trips.
Cranks perfectly.
No diesel odor.
No leaks.
Normal running and normal fuel consumption.
Take a very long while to get the pump hard when this happens.
245,000 km on the clock

Thanks in advance, sorry if this has been discussed, I couldn't find it.

Its possible the sealing on the fuel filter housing isnt up to the job. You will not always see a leak of fuel out of a bad seal as the fuel is sucked through from the tank, and not pumped.

New filters come with new seals, and when tightening the lid ,it is imperative the marks are aligned when tight
