Friend has a 2002 mazda B2300 (ford ranger). turns over but wont start, was told it might be a fuel problem. i checked the relay button @ thepassenger kick panel, the underhood fuse, and the relay. all seem ok. when the key is turned to "Start" i dont hear ANYTHING coming from the fuel tank area. no click, no buzz, nothing. am i in the right direction? is there something else i should be checking first?
