It starts, but why are all the service lights on the dashboard lit up?

Dead battery, most likely.

Change the fuel pump its faulty.

I would strongly suspect a failing fuel pump. Possibly a defective fuel filter, but with the milage, I would think the fuel pump is going bad.

have u changed the fuel filter?

Your alternator is not charging the Battery, I would replace the battery with a new gel battery and have the alternator checked, bets on your battery just died.

Take it to a store like autozone and have them check the computer codes to see what the issue is.

The 04 Santa Fe came with three different engines. 4 cylinder (2.4 lit), and two different V6's (2.7 lit & 3.5 lit). The 2.4 & 2.7 use throttle cables connected directly to the throttle plate, but the 3.5 uses ETS (Electronic Throttle System) which uses two sensors (APS & TPS) and a control module (ETSCM). APS=Accelerator Position Sensor, TPS=Throttle Position Sensor, ETSCM= Electronic Throttle System Control Module. There are different diagnostic procedures for each system.

It won't die when pulling the relay because it has another power path to the fuel pump through the oil pressure switch . Fuel Pump Electrical Circuits Description and Operation watch this video on fuel pump control , shows chrysler first , ford ,then gm . wait for gm an he explains the oil pressure switch . Plus when it won't start ,don't guess or theorize ! Test what's missing ? check for spark , no spark check ignition system , coil's , ignition module , crank sensor etc... has spark ,do a fuel pressure test etc... don't think computer , when it won't start does the check engine light come on with the key on run not start . If light is lit ,nothing wrong with the cumputer . If want to fix cars you really should take some automotive classes . Test don't guess .Watch some other videos crank no start videos etc...

Check belt(s) first then put voltmeter on battery and record voltage while running if you can, even if you have to jump it to get it going. take time to read owners manual & locate any fuses that may be associated with alternator circuits, most likely in power distribution box under hood, and check for one blown. Do you have a 12v test light by chance?
