Weather here has been in the 40s to mid 50sso i have been driving the car more lately and i noticed an issue. If i turn the key to glow plug on and then to crank it crank before the glow plug light is off it will crank every time. If i wait to turn the key once the light is off, i might have to cycle the key 2 or 3 times before it will crank. So i dont know if this is a sign of the glow plug relay failing or another part of the start circuit going bad? Or is this normal based on my outside temp?
