It sounds like there is a short somewhere. One of the wires going to your relay is touching bare metal somewhere, causing it to overheat, but not enough to make it stop working.

fuel pump relay is under the hood in the fuse/relay box. information is in your owners manual.
when was the last time you replaced the fuel filter, maybe its plugged?
check the fuel pressure(min of 45psi)under the hood at the port. if thats ok, check for intermitten spark(esc)electronic spark control may be getting hot and missing a beat....if thats ok then check the MAF sensormalfunction, but you should have a code for all but fuel pressure.good luck
it all depends on if the wire does or doesnt have power when u shut the key off, if it does the pump will run non stop even with the key out,i would suggest getting the relay working properly,also depending how u hook it up u dont want too much voltage runnin through the relay...u could melt it,hope this helps
To test the circuit before removing the tank, you will need a voltmeter or cheap test light. Disconnect the connector at the fuel tank. On the harness side, locate the gray wire (fuel pump wire). Connect the test light to a good ground. Have a helper crank the engine over. While engine is cranking, the gray wire should have power. If it does, and the pump is not turning on, then the pump must be bad and need replacing. If there is no power on the gray wire with engine cranking, the circuit is the problem, not the pump. Go back and find the fuel pump fuse in the junction block (the fuse relay block where the fuel pump relay is). Check the fuse, also check if there is power going to the fuse. This fuse should be hot at all times. The circuit goes from battery to pump fuse to fuel pump relay to gas tank and the fuel pump.
Injectors or Carb? is there fuel presurt to the line near the engine and what is the presure.
The mechanoc was it a shop or buddy at home? Can you hear the fuel pump run when the key is turned on?
where is fuel pump relay
