P0734 means that your transmission is slipping. This being the case, it is not surprising that the gas mileage is poor. You will need to have your transmission checked out professionally. Take it to a trustworthy transmission mechanic or to a dealer. Get a second opinion before you have any work done.

Having problem with trying to gas up the elantra. gas pump handle keeps clicking off. have to squeeze handle real lightly to fill up tank takes a long time to fill up. help


I know you probably won't like my answer, but seeing as I am a service tech for gas stations, the nozzle has a safety feature which shuts/kicks off when gas splashes back into the nozzle, thus keeping the gas from running over when the car is unattended and nozzle is locked. You can try pulling the nozzle back til it is barely in the tank or try a different gas station as some nozzles are different. As it is the shape of the fill tube on your vehicle. Hope this helped Tim

My 2000 Hyundai Elantra runs rough and my code reader says that cylinder #1 is miss firing. I replaced the spark plug and gaped it, checked the wires and they are good, replaced the injector and the coil...


Is your check engine light on? I have the same probelm with my 2002 Elantra. I think it may be connected to the O2 sensor with regulates the emissions, and can cause poor fuel economy. I know I need to get it fixed, but am waiting for funds to do so. Does it seem worse after you fill it with gas? I am just curious since that is what mine does.

sounds like a bad fuel sending unit in the tank, however , i find it hard to belive that the dealer wont take care of that, unless you bought it as is with no warranty, and no work promised

2000 hyundai elantra starts when it wants to


The problem you describe has many possible causes. Any number of engine management sensors (which are starting to go bad) can cause this problem, the fuel pump is starting to go bad, the engine computer, wiring, connectors, etc.. the list goes on and on. My experience tells me to tell you to take the vehicle into a Hyundai Service Center and try to get it diagnosed. If successful, they'll give you an estimate of repairs (parts, labor, tax, time-frame, etc.). This way you'll know exactly what's wrong and what's required to fix it. Now, since the problem is 'INTERMITTENT', that makes it tough for the technician unless he/she can discover any DTC (Diagnostic Trouble Codes) stored in the computer (ECM - Engine Control Module) - Did the 'Check Engine" light ever come ON? If so, this will help narrow the search and diagnosis.

2000 Hyundai Elantra starts only sometimes.


Here is a view of where the fuel pump is located (in the gas tank) and what all the components look like. Good luck.

Engine riding rough


if it has a check engine light the simplest thing to do would probably go to auto zone or advance and ask them to do a code check,its free and will probably tell you the problem and take allot of the guess work out of it.
