hey guys. have a 1992 743B. got home from work and went to fire it up yesterday. i turned the key back for glowplugs, then turned to start and it didnt click like it normally did when u turn it to just before the cranck position. so i went to crank it anyways and no fire. is there a fuel solenoid or a relay somewhere that may be the problem? need help soon as i need to use it today, thanx wayne
