Question about Cars & Trucks
There are several things that can cause this. There is a vent hose or the main hose to the tank from the filler that could be kinked, collapsed orr plugged. There may be a emissions valve on the filler neck that is bad too, they are not easy to deal with because the tank should be emptied and the vehicle raised and remove the gas tank. Difficult to do and dangerous due to fire and explosion hazard.

The anti siphon in your tank fill tube may be damaged or stopped up or the vent/ evap system stopped up. I would check anti siphon first. it is in the fill tube at the top of the tank.

Power Stage (DMTL Motor)
Power Stage (DMTL Valve)
The 2000 model year Accent adopts a new "pressurized" leak check system capable of detecting a 0.020" (0.5 mm) diameter leak (previous Hyundai systems detect a 0.040" [1mm] diameter leak using engine vacuum). The new system uses a Diagnostic Module for Tank Leakage (DM-TL) to close and pressurize the fuel evaporative emissions system. The DM-TL replaces the fuel tank pressure sensor and the canister close valve from previous systems. Other significant changes were made to the system logic, including several new diagnostic trouble codes. The diagnostic module (refer to photos on page 3) consists of a motorized air pump, a solenoid shuttle (sealing) valve, and a 0.020" (0.5 mm) diameter reference orifice. After the vehicle meets the self check requirements (see Self Check Requirements When Not Using The Hi-Scan Pro Section), the DM-TL activates to check for system leakage. The air pump and shuttle valve work on the command of the ECM. Motorized Air Pump - the pump pressurizes the evaporative emissions system producing a current draw that the ECM reads to determine pass/fail conditions. When the pump is switched 'ON', current draw is typically 17 - 36 mA. Solenoid Shuttle Valve - the shuttle (sealing) valve has two sealing sides (front and rear) that provide two functions: A. When the valve is "OFF" (no voltage aplied to valve), the front sealing surface directs air from the air pump (if it is "ON") through the 0.020" (0.5mm) diameter reference orifice. The rear sealing surface is openand provides an open path between the charcoal canister and freshair. B. When the valve is "ON" the front sealing surface is open directing air from the air pump into the evaporative emissions system. The rear sealing surface is closed, sealing off the evaporative emission system for the leak check. 0.020" (0.5 mm) Diameter Reference Orifice - the built-in reference orifice provides the ECM the current draw of the air pump motor for current ambient conditions (temperature,humidity etc.) to determine pass/fail conditions duringthe system leak check. P1402 DM-TL Circuit Continuity Check (Pump Motor) - short circuited, or disconnected. P1403 DM-TL Circuit Continuity Check (Shuttle Valve) - short circuited, or disconnected. IMPORTANT NOTE!.. you have a fuel leak now. These codes are NOT a direct cause of that leak... they are a result.
It is highly recommended to use the Hyundai Hi-Scan Pro to activate the evaporative emission self check. Using theHi-Scan Pro will save time and provide more consistent results. Moreover, "road testing" of the evaporative emission system in a 2000 MY Accent is not practical (requiring up to a 4day time frame to verify a repair). The leakage self check can be found on the main menu after selecting Model and Year of the vehicle. For the 2000 Accent, the menu item is labeled "DM-TL Test". To familarize yourself with the operation of the self check, remove the fuel cap of a 2000 Accent that is operating properly and activate the self check (follow the instructions on the Hi-ScanPro screen). With the fuel cap removed, Diagnostic Trouble CodeP0455, or P0442 will register in the ECM memory after the test is finished. (NOTE: The "Check Engine" light will not illuminate because the self check has only been run once. However, the code will be stored in the ECM memory. The "Check Engine" light will illuminate if the ignition key is switched to off, and the main power relay shuts off, and then the self check is performeda second time.). Erase the code when finished, and securely replace the fuel cap. If no code appears, turn the ignition key to off until the main power relay shuts off and retry the process. If no code appears at this point, call the Hyundai Tech Line. 7. SYSTEM SELF CHECK REQUIREMENTS (WHEN NOT ACTIVATED BY HI-SCAN PRO) For verification of a repair, it is highly recommended to use the Hi-Scan Pro to activate the self check. The importance of using the Hi-Scan Pro can't be over-emphasized because of the different self check requirements for the 2000 Accent. Use of the Hi-Scan Pro bypasses all of the self check criteria described below, allowing the technician to perform the self check at anytime, regardless of the conditions. Under normal operating conditions, the leak check occurs almost immediately after the vehicle is shut off and items 1-8 have been achieved. The ECM"s prerequisite for this check areas follows:

check the impact saftey switch to see if it was tripped it should be listed in your owners manuel. It is a saftey feature in case of a collision it shuts down the fuel pump

power steering need bleeding if your reservoir was dry when you added fluid if.fluid was okay not too low.your power steering pump could be faulty.the cold weather will effect it.
