2007 Santa Fe won't start

An OBD scanner is a great tool to start your trouble shooting with, because even though many of the electronic controls on a vehicle will trigger the Check Engine Light, many times a trouble code(s) will show in the ECU memory even though the check engine light is not on. Some codes will just trip a flash or two of the light which we may not even notice while driving. If you do your own repairs or just want a better idea of what your problem is before bringing it in for repairs, it is worth while to own one, especially since they are relativly inexpensive now. Having said that, I would start by checking for stored trouble codes because it will make things much easier to fix if there are any stored, and you start your repair(in theory) by checking and/or repairing the item that caused the first code in the order the codes have displayed. I have found that this will always vary by manufacturer or model, as in recent times I hade multiple codes show on 2 of my vehicles, and the problem part was somewhere in the middle of the list. Your particular problem sounds similer to a fairly common one found in many or most Hyundais. It involves a vent/purge valve & solenoid combination of controls found in a canister under the floorboards, under the front seat area. There is also a filter in there. Either of the two, or even both of them could be going bad or have already gone bad. These starting/running problems usually manifest themselves either right after or very shortly after filling the gas tank. Sometimes the vehicle will start and run great right after filling it and other times you may have a hard start condition when you go to start it to pull away from the pumps. If it starts and drives ok, it will usually show up as a hard start & stalling problem within a few start/drive/ shut down cycles, but always a short time after a tank fill. A code scan should tell you if this system is your problem. If it isn't, it could be several other problems, such as Idle Air Control Valve, Mass Air Sensor, a vacumn line problem, or depending on the year of the veh, it could be a pair of valves located in the cylinder heads which open and close based on air and electrical data, and these tend to fail and cause problems because of a shoddy design that causes one or both of them to operate differently instead of together. It may also be a clogged fuel filter or even a bad or failing fuel pump. Just be aware that if you do scan and get codes then take it to a shop for repair, most shops couldn't care less what codes you have, they will insuist on charging you a diagnostic fee, which is that they basically use their scanner to do exactly what you have already done with your scanner. They will usually apply the cost or most of the cost to the actual repair, if you have it done by them. Please keep us posted on what you find.
