2000 Mercury Cougar fuel system complaints
Page 3 of 3: complaints 41 to 46 of 46, newest first, as owners wrote them.
When driving approx 50 MPH in 4th gear, car started to buck and chug, slowed down to 25, and stopped at stoplight, car chugged once and killed/stalled. Could not start, after 30 min car started but stalled after moving 10 feet, seemed as if car wasn't getting fuel. Dealership and first diagnostic test blamed fuel pump and they kindly replaced fuel pump for $100 deductible (car 5000 miles out of warranty). Yesterday, 4 days later, driving 70 MPH w/cruise control on, chugging/buckinh reoccured, and then car MPH started dropping fast, downshifted into 4th, pressed gas and nothing happened. Pulled over (car never killed) and put car in 1st gear and took off, 5 miles later it happened again (4 times total). Called dealership, blamed bad gas or water in the tank freezing in cold weather, both occurances happened at 1/4 tank of gas, added "heat" to remove any water, and will see what happens next time I am at 1/4 tank. Problem does not seem water/gas related problem is intermittent.
Vehicle stalls due to fuel pump failure.
Vehicle stalls while driving. At times, vehicle will jerk / stall. Vehicle will not restart. Contacted dealer, and dealer replaced fuel pump. Please add VIN.
Consumer had three fuel pumps replaced within the year because vehicle stalled without prior warning.
Fuel tank needs to be replaced . This is 3rd time due to faulty seal which causes fuel leakage . *ak
