This is my first post, Need help with a 6.5 liter in a 93 chevy 1 ton. Glow plugs have given problems starting.
If glow plug dash light comes on and cylces unit starts but takes 2 cycles to start quickly. If light fails to come on and cycle then it will not start. Have replaced glow plug relay 4 times and starts well for about a month, then back to hard start. Any ideas?
6.5 liter gm diesel
