Well, I installed the new glow plug relay today, check the resistance and voltage on the plugs and it was good, but it will still not start. I am stumped. I know the battery is good, the starter is about a month old, glow plugs are good, new glow plug relay. The next thing I believe I should check is to see if the fuel is getting to the injectors and the injectors are not clogged, but besides that any suggestions??
