Fuel system, other: delivery: fuel pump
- What is wrong
- On certain transit vehicles and trolleys equipped with cummins isb-02 diesel engines built with emc controlled fuel lift pumps. Erratic voltage supply to the fuel lift pump causes premature electric brush wear internal to the fuel lift pump. This premature wear could result in fuel lift pump failure and in some cases may cause an engine stall condition.
- Risk
- Should the engine stall, a vehicle crash could occur.
- Remedy
- Cummins, in conjunction with optima bus, will notify owners and repair the engines by emc recalibration and replacement of the fuel lift pump at no charge to the customer. Owners may contact cummins assistance center at 1-800-diesels or optima bus at 1‑316‑779‑7700.
