TBM66 -> 2003 Z71 Potential Fuel Flow Related Issue (2/20/2008 4:01:24 AM)
|
I've seen various references to this problem in other BBS, but no good diagnosis.
Here's the story. We have a 2003 Z71 with 80K miles (this baby has to get us to 200k). When the fuel gauge gets below 1/4 tank AND it sits over night the car will not start in the morning. Add 3 or so gallons of fuel and it will start.
The car will continue to drive and run past 1/4 tank if on a trip, it will also restart if warmed up when the gauge is below 1/4 tank. Therefore I don't think its a gauge related issue.
To my inexpert thinking it appears to be related to the fuel sending unit needing a minimum level (or weight) of fuel to pump correctly when its cold?
Thank you for sharing your expertise.
