when i turn the key the fuel pump should come on for a few seconds then shut off . but i hear the pump on all the time and it is flooding the engine with out starting it . something is going on . i changed the fuel pump module relay box that is located by the over flow tank and the car computer and it is still staying on when i turn the key on with the engine off .
WHAT AM I DOING WRONG AND WHAT SHOULD I LOOK FOR . HELP !!!!!!!!!!!!!!!!!1

First off. You must chill. Second off. I don't think it's flooding it. The injectors shouldn't be pumping the fuel. The fuel pump will just be pumping it to the rails, and then to the return line. So you might have other problems (THis is fox body.. I assume SN95's aren't that different). I Guess I'd start checking wires.. http://www.veryuseful.com/mustang/te...ng_Diagram.gif

Maybe the relay isn't releasing (Would find that odd)...

check the relay. i had a prob with mine staying one even with the key off n out of the ignition. found it to be a bad relay.

if the op is refering to the 94 in his sig then it tain't got one under the seat= sn-95....it has what is known as a ccrm...constant control relay module under the hood mounted to a bracket behind the coolant resevoir bottle
