I've owned my trusty diesel for many years, 125k on the clock, full history etc etc Its never been a great starter and I always have to wait the full cycle for the glow plugs before even attempting to start, I always thought this was just the way they are. I've got a hot start kit, replaced the glow plugs every few years, had the injectors reconditioned etc. Anyway went to look at a £400 spares or repair high mileage abused wreck with well over 200k on clock, and overheating problem. Anyway it stated like a dream every time, no need for glow plug light to go out it just started and even sounded better than mine. Why's this wreck starting so much better than mine? What would you guys suggest I replaced first?
