I just purchased a 2004 Speedster w/a Merc V6 and when I took it out for the first time it started up, got up on plane for about 300 feet before it lost power. I checked the main fuses on the engine, and I also checked to make sure it was getting spark. Those two items checked out. The fuel filter wasn't plugged; however, when I removed the plug on the vapor separator and turned the motor over, no fuel came out. I took it apart to check the filter on the electric fuel pump and that was clear too. I just can't figure out what the problem is. Any help would be greatly appreciated.
