IT WONT START, I ALREADY CHECKED THE SPARK PLUGS, ALL OF MY INTAKE MANIFOLD LINES AND THE FUEL RELAY, IM ABOUT 90% SURE ITS THE FUEL PUMP, THE ONLY PROBLEM IS I DONT KNOW WHICH FUEL PUMP I AM SUPPOSED TO USE. THERE'S ALSO ANOTHER PROBLEM, IM A BROKE *** COLLEGE STUDENT, SO I NEED TO FIND SOMETHING EFFECTIVE AND LONG LASTING AND ABOUT AS CHEAP AS I CAN FIND IT. ANY SUGGESTIONS... WHERE CAN I START... ANY SHOPS??? HELP.
