I've had glow plugs fail with much less than that. Sometimes that area of the pre-chamber gets a build up of carbon and a reamer is needed. You can usually get a general idea of their condition by using a multi-meter set on Ohms. A typical reading from the connection to ground is about 1.0 ohm. Just two failed ones will give you problems.
