Asked by Jul 29, 2014 at 06:15 PM about the 2003 Hyundai Elantra

Question type: Maintenance & Repair

It will start fine. runs smooth. Then suddenly without warning, shuts off. i still have lights
and radio but its like someone turned off the car. It does not sputter or hesitate. it simply
shuts off. cannot restart it until it sits for several hours. When I try, it sounds like its trying
to start but simply wont turn over. My battery is new. ust changed the fuel pump. Its still
happening.

Hmm not sure...Had a similar issue w/ my '02 Elantra. Check Engine light had been on for a while, was told it had to do w/ oxygen sensors. Most recently the car would stall, idle at very low RPMs, and did not have much power and would sputter through turns. End result was only a clogged fuel valve, and that seems to have done the trick. A lot of these issues posted regarding older Hyundai Elantras seem to all relate back to the fuel source...good luck...

If you have already replaced the fuel pump, I would suggest removing and cleaning the throttle control body. This is a known issue in older models of the Elantra, but is a simple fix. It shouldn't take more than 30 minutes, start to finish. Just use a clean cloth, rinse often, and MAKE SURE that the throttle control body is completely clean AND dry before reassembly.
