had starting problems. ordered new fuel pump relay. when it arrived it had four pins on one side instead of three. the extra was numbered 87h. i used it anyway but didn,t cure problem. don,t know if it was defective or if the extra pin was problem. i then jumpered pins 30 and 87 and car seems to run ok. will it do any damage to run with the pins jumpered till i order another relay? and does the extra pin cause a problem? thanks barry
