Motor starts but miller furnace will not fire then motor shuts off

As I said to another poster, if you post a clearly written description of what you need, the equipment involved, a fuller description of symptoms or incorrect operation, you have a better chance of getting good advice. I don't even know what type of fuel we are dealing with here. We are NOT clairvoyant.

Read sticky #1.

Sounds like a miller oil fired f- air furnace. #1 cad cell eye could be bad. #2The relay itself could be bad.#3
The coupler bettween the motor and pump could be bad.#4 or you could be out of fuel. If you are not out of fuel, and you keep resetting the relay, your pumping fuel into the combustion chamber. You should have a burner tec look at it before you go BOOM.
