Just had a really bad cold start on my 02. i waited until the wait to start light went off and tried to crank it over and it sounded horrible so i backed off. so i turned the glow plugs on again figuring that they werent hot enough yet. it started after a very slight push of the throttle, but it sounded like it had no cranking power and not as horrible. It has never done this to me in the past. I just put in some diesel fuel additive in it (like a half tank ago) due to the very cold weather that came in the area. Just think trying to get everyones thoughts on this. Cause im thinking i may have to go run to the store quick and put a heater in her.
