I have been having a problem with a 30amp fuse blowing for awhile. This fuse controls the gauges, tow/haul, AIC, 4x4 engagement. Dealer has attempted to fix the problem 3 times now, the last fix was to replace the entire gauge cluster.
But now I am having a problem with the water in fuel light coming on after about 4 minutes of run time. I have drained the water/fuel drain 5 times now. The first time there was a very small amount of water/moisture present, the following 4 times there has been no sign of water/moisture present. I am draining the fuel into a glass jar and can see no seperation of fuel and water present.
Has anyone had or know of a problem of faulty sensors in the separator.
I have tried switching tanks (I have dual tanks) and the problem exist with both tanks, (which were not purshased from the same fuel stop).
There is a known issue with the early water in fuel (WIF) sensors. I was having the same problem as you in our 2004 - no contaminants in the drained fuel, but the WIF light was on. The sensor was replaced, and when the problem recurred the fuel pump was replaced.
I guess I will run it into the shop and let the warranty take care of it. Mine is also an early 2003 model run, been very dependable up till this last few weeks............of course I guess that is because the 36/36 warranty is 5,000 miles from running out.
What is happening, is that the water sensor
has become gummed up. On the 6.0 the fuel
pump, water seperator, fuel filter, and fuel
heater are all built into one unit. I have
two friends that had this problem. Add some
type of fuel conditioner in every tank fuel.
This will keep things clean.
