Re: 2004 sonata 2.4 engine
The filter may be on the firewall or under the car by the fuel tank.The studering wouldtell me that it needs plugs and wires.If it is running smooth but no power up hills or hard take off I would have the fuel pressure checked.

It depends on which engine is in the vehicle. The 2004 Sonata came with two possible powertrains -- the 2.4 Lit L4, and the 2.7 Lit V6.
On the 4 cylinder engine, there are two coil packs and two ignition wires, Below each coil pack is a spark plug (#2 and #4 cylinders). The wire from # 2 coil pack goes to #3 spark plug, and the wire from #4 coil pack goes to #1 spark plug.
Now the 2.7 Lit V6 requires you remove the surge tank (intake manifold) in order to access the spark plugs & wires on Bank 1 (Right Hand side of the engine).
You are describing low fuel pressure (fuel pump) problem. When you say you replaced the fuel filter, where did you find this filter on the 2004 Sonata? The problem, there is no Fuel Filter, per se, there is a 'SOCK' at the bottom of the fuel pump assembly which serves as a filter, inside the fuel tank. By the way, you mentioned the Check Engine Light came on. Did you scan for any codes in the computer (ECU)? If you did, what were the codes?
Hi, the fuel filter is by the front of the gas tank. but the person was right about the strainer on the fuel pump but that is just the first filter to keep large sediments out, and secondary filter is to keep the small stuff out.
hi is there fuel getting to engine?any vapour coming out exhaust?sometimes glow plugs not working can cause this.try a squirt of easy start into air filter.NOT MUCH!!READ INSTRUCTIONS.HIGHLY FLAMMABLE.then start car for about 10secs.get this from car accessorie shops.if it fires on this its highly likely glowplugs not working or fuel pumptiming out.its hard to say without seeing the car
It sounds like you need a new fuel filter. if that is to dirty, it wont allow the correct amount of full to be pushed to the engine. try changing that or using a Fuel treatment in the meantime. Hope this helps :)
