# RV Generator Will Not Start, the Common Causes

> A generator that will not start usually points to fuel delivery, a control board, a worn component, or low oil protection tripping it. A real diagnostic finds the actual cause instead of guessing. We service Onan and Cummins generators from no start diagnostics to full overhauls.

## Where to start looking

- Fuel delivery and filters
- Oil level, since low oil protection can block a start
- Control board and start circuit
- Worn or fouled components from sitting unused

## Diagnose, then repair

Generators that sit unused are the ones that fail to start, often from stale fuel or a tired component. We diagnose the actual cause rather than swapping parts, then repair it so the generator is reliable again.

## Frequently asked questions

### Can you fix an Onan generator that will not start?

Usually yes. We service and repair Onan and Cummins generators, from no start diagnostics to full overhauls. We find the real cause, whether fuel, a control board, or a worn component, and repair it instead of guessing.
