Sorry for the long list, been trying to keep track of everything.
Has anyone come accross this problem before, Hard to believe that all these parts go bad at the same time. Any ideas on what
we may be misssing. Tried of taking vehicle to the shop.

The fuel pressure sensor was bad at the start and all the the other repairs wasn't needed, thats the trouble with these emission problems, they are very had to find, even with test equipment it still can leave you scratching your head, but I would talk with the people who done the work about all the parts that didn't fix the problem that wasn't needed, cause you shouldn't have to pay for that or at least half of it should be refunded back to you.

Thanks for the reply Dave284.
Fuel Pressure sensor did not repair the code.
Picked my Explorer up on 07/17/2008 from the repair shop.
On 07/18/2008 at 160,340 miles another code PO442.
Check engine light came on the next morning on the way to work.
Repair shop said it tested ok before I pick it up.
Thinking about putting tape on Check Engine Light, LOL
But can't do that because it would not pass the E-Check.
Back to the Shop.

Check the evap vent hose that runs off the emissions cannister. These are constantly getting road debris and spider's nest built up in them and causing that code to trip. Also check connections at the purge solenoid to be sure there is not a small leak there.

Being way2old is why I need help from younger minds

Picked my vehicle up from the Dealership today (07/22/2008).
They checked the repairs from the other repair shop, smoke tested the system and found the filler pipe leaking.Unsure. Had them replace the filler pipe. Oh the cost!!!!...Crazy
Do not know if this was the problem from the start or if it was cracked during the Fuel pressure sensor install.
No way of knowing.
Have put a 120 miles on it today and no codes yet. Hopefully it is fixed. Will keep scanner in the vehicle and
check off & on.
