Question about 2004 Hyundai Santa Fe
First of all, that 'ticking' noise you mention, if it's what I think it is, it's normal (purge control solenoid valve) being modulated by the ECM to **** the vapors back out of the charcoal canister. The 'Hard Starting' condition you describe could be almost anything from fuel (fuel pressure, fuel pump, injectors), timing, air leaks, vacuum leaks, crank position sensor, etc.). You'll want to connect a fuel pressure gauge to the fuel feed hose/tube at the engine fuel rail (where the injectors are) and monitor the pressure when this hard start condition occurs so you can at least eliminate it as the cause. If you find the pressure is low or 'intermittent' or 'fluctuates' abnormally, you'll want to inspect the wiring/connections between the fuel pump fuse and the fuel pump connector - repair/replace as needed. If the wiring/ connections are good and you have power & ground at the fuel pump, then the problem is probably the fuel pump.
