It's all in the VIN.

A car’s vehicle identification number (VIN) is the automotive equivalent of
human "DNA".

How to read a VIN
1st character- Identifies the country in which the vehicle was manufactured.
For example: U.S.A.(1or 4), Canada(2), Mexico(3), Japan(J), Korea(K), England(S), Germany(W), Italy(Z)
2nd character- Identifies the manufacturer. For example; Audi(A),
BMW(B), Buick(4), Cadillac(6), Chevrolet(1), Chrysler(C), Dodge(B),
Ford(F), GM Canada(7), General Motors(G), Honda(H), Jaquar(A), Lincoln(L), Mercedes Benz(D), Mercury(M), Nissan(N), Oldsmobile(3), Pontiac(2or5), Plymouth(P), Saturn(8), Toyota(T), VW(V), Volvo(V).
3rd character- Identifies vehicle type or manufacturing division.
4th to 8th characters- VDS - Vehicle Descriptor Section. These 5 characters occupy positions 4 through 8 of the VIN and may be used by the manufacturer to identify attributes of the vehicle. Identifies vehicle features such as body style, engine type, model, series, etc.
9th Character - The check digit "character or digit 9" in the sequence of a vehicle identification number (VIN) built beginning with model year 1981 (when the 17 character digit format was established) can best be described as identifying the VIN accuracy.
A check digit shall be part of each vin (since 1981) and shall appear in position
nine (9) of the VIN on the vehicle and on any transfer documents containing
the vin prepared by the manufacturer to be given to the first owner for purposes
other than resale. Thus, the vins of any two vehicles manufactured within a 30
year period shall not be identical. The check digit means a single number or letter
"x" used to verify the accuracy of the transcription of the vehicle identification
number.
After all other characters in the VIN have been determined by the manufacturer
the check digit is calculated by carrying out a mathematical computation
specified. This is based on vin position, sample vin, assigned value code,
weight factor and multiply assigned value times weight factors. The values are added and the total is divided by 11. The remainder is the check digit number.
The correct numeric remainder - zero through nine (0-9) will appear.
However, if the remainder is 10 the letter "X" is used to designate the check
digit value/number.
10th character- Identifies the model year. For example: 1988(J), 1989(K), 1990(L), 1991(M), 1992(N), 1993(P), 1994(R), 1995(S), 1996(T),
1997(V), 1998(W), 1999(X), 2000(Y)------2001(1), 2002(2), 2003(3)
11th character- Identifies the assembly plant for the vehicle.
12th to 17th characters- VIS - Vehicle Identifier Section. The last 8 characters of the VIN are used for the identification a of specific vehicle. The last four characters shall always be numeric. Identifies the sequence of the vehicle for production as it rolled off the manufacturers assembly line.

ford explorer eec relay

before i changed my fuel pump. I started my explorer and it ran for 4 seconds then turned off. My 1st instinct was the fuel pump. I changed the pump, and it still didn't star. Checked the fuses under the hood and saw that the eec relay fuse was blown. I tried different fuses and the same happened. What do i do

Try a new relay first. This may not be good news if that does not work. If you can find the EEC (computer) and unplug it, then replace the fuse-if it blows you have another cheaper part on the circuit thats bad.
If the fuse does not blow, then the EEC must be shorted.
If you have to replace the EEC you may find a kindly dealer with a cash-for-clunker sitting there to violate. Salvage yards have them, Ebay sells them. I have seen them at swap meets for $20. They are a high price part even rebuilt at Dealers or autoparts stores.

Also Replace Valve Body Gasket. They do blue out which will cause this hesitating. If doing it yourself check 11 auto on You Tube. Good luck
