Take Care, Very Simple Things Matter.
I own a Ford Expedition, I am not a Ford lover but we always upkeep our vehicles and so far no problems with our Exp. Replacement of things are expected, but not a huge cost when the oil is changed on time, fuel filter once a year, and brake pads. Oxygen censors just went out at 165,00 miles. So not complaining, another good thing to do is to add a bottle of Teckron fuel injector cleaner once a month, get it at costco, 6 for 15.99. My mechanic would yell at me if he sees it under 1/4 tank of gas! so pretend that 1/4 means empty. good luck.
Go to local auto store, buy a Chilton manual and see if you can intasll a new fuel pump or get an online auto repair manual from this site, link at top left. But if you can disconnect the fuel line, place fuel line into a gallon jug, (use help). Turn vehicle key to ON and see if you get alot of gas within seconds. Yes a fuel pump pressurizes the fuel rail, so time sitting is allowing it to build pressure. But a bad coil can do this, when they get hot, it creates an OPEN , which you get no spark-there for you crank, crank, crank the engine. When it cools down after sitting the Open now makes contact and you can start the vehicle. Also when you drive for a longtime, it shruggs or purges at a stop light or even while driving. Due to the heat in coil. $40.00-$80.00 usually for a new coil. $65.00-$120.00 for a fuel pump, usually. A simple $85.00 to have vehicle diagnostic check will tell you what to do, from a local GOOD shop. Dealer is $120.00 for the same. Shop must call and tell you problem and get your approval before they can fix it. So always DEMAND a call, before any repair is made. $1000.00 is too much to replace of a fuel pump. Try another shop-not a backyard crackhead jerk! Autozone, Pep boys, Kragen will do a free diagnostic check for a code, if your dash shows Check Engine light is on. Good-Luck!!
It would be best to start by extracting any cenrurt and history codes. This may guide you oin the right direction. Could be any number of things.
