20 Most Recent Hyundai Motor 2003 XG350 - Page 5 Questions & Answers

First and foremost, has anyone VERIFIED that the CAUSE is the fuel pump? Hard starting has NUMEROUS possible causes -- wiring, connectors, sensors (MAF, MAP, TPS, APS, ETS Motor, IAT, ECT, CKP, CMP, etc.), injectors, timing, air flow, fuel pressure, contaminated fuel, vacuum leaks, Powertrain Control Module (PCM - garbage in memory - adaptives), The more sofisticated the technology, the more COMPLEX the diagnosis. It seems you have an INTERMITTENT malfunction in one (or more) EMS (Engine Management System) components. The only way to diagnosis this is when that particular component acts up! My first suspicion is the MAF (Mass Air Flow Sensor w/Intake Air Temperature Sensor-IAT and/or the Engine Coolant Temperature (ECT) sensor. The possibility also exists that the technician who examined/inspected your vehicle wasn't the swiftest of mechanics - meaning he/she didn't fully understand what they were looking at/testing. Hyundai Shop Manuals aren't the best either. There's no possible way for me to DIAGNOSE your problem without PHYSICALLY examining your vehicle. SEVERAL SOLUTIONS: You can educate yourself regarding the systems installed on your vehicle & attempt to fix it yourself -- Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle. OR, you can take the vehicle back to the Hyundai Service Center (dealership), and tell them to FIX IT! OR, hire an attorney & file a lawsuit. The latter being the last resort.

Most parts stores can code check the car for you.

DESCRIPTION: The security system keyless adapter cable (SPX/Kent-Moore P/N 09900-21300) is a special service tool (SST) that is used for programming new keyless entry remote transmitters to the factory security systems. The keyless adapter is used in conjunction with the Hi-Scan Pro (with Hi-Scan SOL Pro Software Version 09-29-03
or newer) and Data Link Connector (DLC) Cable. SERVICE INFORMATION: The keyless adapter cable can be used on the following vehicles:

• 2001 - 2004 MY Elantra
• 2001 - 2004 MY Santa Fe
• 2002 - 2004 MY Sonata
• 2001 - 2004 MY XG300/350

NOTE

• The 2003 - 2004 MY Tiburon does not need the Keyless Adapter Cable to add keyless entry remotes to the factory security system. Instead, the Hi-Scan Pro connects to the vehicle using only the DLC cable. See page BE-60 in the 2004 MY Tiburon Shop Manual for the latest instructions.
• The most current Keyless Adapter Cable Instructions are available in the following shop manuals:

I've informed you of what you need to do. Take the veh into a Hyundai Service Center - let them program the remotes.

Again, the remotes can only be programmed by a Hyundai Technician (ETACS - Electronis Time and Alarm Control System).

its a transmission cooler thermostatic control valve. its a dealer only part.

it sounds like upper strut mounts or the struts themselves need to be replaced try autozone.com to see if they have your car listed for diagrams pictures and step by step instructions if your car is not listed then try your local library they have all the car manuals and even copy them for you

can you check with dealer

cars these day are all electronic
the exhilarate in your car is electronic the older cars used to have a cable that ran to the motor now they dont
these days the exhilarate is like a volume knob on a cd player, it tells the car to produce more power on not to.
it sends the message to the throttle body
the throttle body is in charge of mixing the air to fuel ratio more fuel more power your emmissions system is the exhaust system
all of this could be linked to the throttle body being damaged
if you want to know more just ask
hope it helps

If its a V6 front wheel drive, 3 on the left head (rear) and 3 on the right head (front) if it is a straight 6, all 6 are in line on the single head. 4cylinder, all 4 in line on the single head......Mike

code p1155 refers to electronic throttle system (ETS)- malfunction===causes --wiring--ETS limp home valve code p1193 refers to ETS -limp home valve --on===causes --Low RPM code p0302 refers to cylinder 2 misfire detected===causes--engine mechanical fault--wiring---ignition/ fuel system---injector---ECT/MAF sensor---ECM. Pulling a battery lead to reset is a waste of time as it corrupts the CPU program. Use a code reader to reset . It is quicker and doesn't run the risk of program corruption

Cheaper to start with fuses but It could also be the relay box if you look at the back of the cover that is covering the fuse box there should be a diagram showing were each fuse. Not 100% shore but worth checking as there could also a fuse box with fuses and relays in the engine bay Let me know if this helps Regards Craig

Ask google and be sure to ask for images!

The fan kicks in when the car reaches a certain temp. Try running it for a few minutes and keep your eye on it. If it doesn't run at all, could be a bad thermostat or simply a fuse.

Leaking coolant is an issue. Look at your radiator hoses. They should not be bulging, cracked, split, or dry rotted. If they are, they need replacing.

When a car reaches temp the thermostat tell the fan to start, and coolant starts circulation through the water jackets (little channels in the engine block). If this isn't happening, your car will over heat and engine damage will occur.

When I did a timing chain on my Datsun I set up TDC on number 1 cylinder and then used a dob of paint on each pulley and a fixed point on the engine so that I could make sure everything lined up the same when I changed the chain.
