Hyundai Elantra GLS 2003 starter does not work

Question edited for clarity.

Possibly, some do cover things that affect starting, the 'fuel pump relay' for instance. You need to diagnose, not just replace as a guess. Check for codes. A prograde scan tool will diagnose all modules and relays.

Look for a hose coming out of your firewall running down to the bottom of the car

Hi Warren, I had a 1995 Elantra and they were very good at reusing their tehnology on all their models. What engine size are you talking about here. Mine was 1600 GLS but there was a 1800 GLS as well. On the Sonata some had bigger engines which may have required stronger starter motors, so please check first.

Re-read your question.......

Have u checked the main fuse in the car? Should b like an 80amper, good luck!

WHERE IS AIR CHARGE TEMP. SENSOR LOCATED ON A 2003 HYUNDAI ELANTRA

Did you use a aftermarket O2 sensor or a genuine Hyundai one? If it's an aftermarket one it may be bad or not as good as the OEM one. See here for more details and other potential causes: P0133

The fuel filter is in the fuel tank attached to the bottom of the fuel pump... it's called a 'sock' and doesn't need replacing.

Two seperate problems. I would say you have a bad wheel sensor. A trip to a local big chain parts store will tell you. They will run a diagnostic and pull the code for free. Hope this helps...

Very wild guess. I replaced the bearings in my 2003, and was looking in my tool box. I came across a 1 1/4" socket that I purchased around the same time, but I realize that it should be the metric equivalent of this, so it probably did not fit perfectly. Metric conversion would be 31.75 mm.
