Explorer Not Starting
I was having troubles with my explorer not starting once in a while. I hooked a fuel pressure guage to it and the pressure when you turned the key on but not the motor wasn't very high. Changed the fuel filter and that eliminated the pressure problem. I am hoping this eliminates the failure to start occaisionally problem. I have attached a picture of the old filter and contents that drained out of it. It was pretty dirty. By the way the truck was a 4.0 L OHV with 40K miles on it.

But what year is it
The fuel system changes a lot for the later models. For the older fuel system, pressure should be around 39# prior to starting and low 30's at idle. Removing vacuum line to the regulator will cause the pressure to go to the high value. Old regulators can leak down pressure and cause hard starting. Fuel rail should hold pressure over 20# for at least a half hour. Fuel filter clogged at 40K! This story isn't holding together.

What manual do you get 15K out of?
I thought Ford recommends 100K.
So what year is this and how did you know it was clogged, pressure drop? A clogged filter at 40K means you live in a third world country. Or is it 140K? I looked at the picture and I blow mine out too to look at the contents. Never had any where near that much dirt at well over 100k on any of my vehicles. Any water in that mess.

I posted this topic looking for help. I don't need you telling me that the filter shouldn't be that way. I kinda realize that. My question was do you think this was the culprit. That is all. No, I don't live in a third world country either. I live in central florida. I thought it was kinda dirty myself. I changed my Tundra's fuel filter at 45,000 miles and didn't have anywhere near that amount of crud in it. I also get gas at the same places she does......

Analyze the sediment
Let it dry on a paper towel or coffee filter. Is it rust or dirt of some sort. I put a lot of miles on cars and have had to drop many tanks to replace fuel pumps. In every case but one they were spotless. The one bad tank was from a 75 PU that had a hole in the top of the tank and almost 4 gal of water in it. If your tank had a hole in it you would get an evap emissions engine code. That leaves gas from a station. With the EPA requirements for new tanks, contamination from that source is almost an urban myth now. Is your gas have alcohol blend. Still with hurricanes and flooding I can see some stuff getting in. Do you fill this from jerry cans when you off road? You should be able to figure it out from the sediment. Jeep was supposed to have a problem for certain years where a tank coating went into the gas and damaged the pumps.
