I have a 97 tiburon not starting as I tried four or five times last night.I removed the fuel line at the filter and had no fuel coming out when I tried to start so I thought it was the pump.This morning I went out and tried and it started right away.So now I'm not sure what it might be.Any idea's that you might have would be great.Thanks

 

It could be the relay connection or possible connection at the pump.Easiest way to diagnose this problem is to remove the rear seat and gain access to the fuel pump plug connector. You will have to look at a wiring diagram and take a voltmeter to see if you have proper voltage. After you figure that out you can decide were to go from there.
