6.2\'s cold starting I recently got myself and 86 diesel burb. Is it normal for these things to be kinda hard to start when cold? I'm kinda new to this diesel stuff and am used to gassers that start right up first time. The overnight temps around here have been getting in the low 40's. The motor has 302K on it but seems to run great otherwise. I have been resorting to turning ignition wait till glow plug light goes out, push gas pedal half way and crank the motor. Seems it takes at minimum 3 tries before it comes to life. Think new glow plugs will help?
