Auto Parts: starting hyundai excel 1995, coolant temperature sensor, hyundai excel 1995

Question
my car some times does not start in the early morning it has to be pushed after that it will start ok all day and the next morning it will not start   some say that the fuel pump is the trouble maker how do you take off the fuel tank to fix that  what is the real problem?

Answer
    If the fuel pump were bad, then it would never run.  You say that you have to push it to get it started.  Does this mean that the engine won't crank over?  If so, then either the starter or the battery is at fault.  Even if it does crank, it might be cranking too slowly to fire up.  The only electronic component that might be at fault is the coolant temperature sensor.  If it is telling the ECM that the engine is warm, it won't meter enough fuel to get the cold engine started.
