DMC #801; Engine starts, then stops after 3 seconds. Can hear the pump prime every time, after the engine starts, the engine quits. I have felt the pump, it stops pumping after it starts. Once the engine stops, I hear a gurgling in the tank. Any suggestions? Can the fuel pick-up in the tank collapse? What else could it be? Checked fuse # 1 & 7. Jumpered RPM relay Terminals # 87 & 30. Same results. Could it be the fuel relay? Any help would be greatly appreciated.
