Three problems related to fuel pump have been reported for the 2003 Saturn ION. The most recently reported issues are listed below.
Beginning in the fall of 2006 I began to have a problem with the car revving up when the heat was on. At times this problem would stop after an oil change. I have taken the car to the dealership several times to have them take a look at it, but they can never seem to recreate the incident and have not found any thing with diagnostic testing. Most recently I replaced the fuel pump because the car was having other problems. I am no experiencing a safety issue. When the car is on and has been running for at least 5-10 min. The engine reves up and the car idles very high 3 or 4 rpms. When I stop at a light or stop sign or for whatever reason the car stops fine but continues to idle high. The car has begun to lung forward when the engine idles high. I have had the brakes inspected and this is not the problem. I am not sure where else to go the dealership has not been able to help me and I am afraid that someone will get hurt because of this problem.
The timing chain broke on the vehicle. All I did was go to start it up and it wouldn't start. I had to have it towed to a goodyear but they couldn't fix it. So right now it is being looked at by a mechanic. He said that the timing chain is broken and because of the breakage I now have to have the valves replaced as well as the thermostat, the fuel pump and the head gasket. All of these were damaged by the chain. This is now costing me approximately $3000. All of which is caused by a faulty belt that Saturn installed on their vehicles.
: the contact stated while driving on the freeway between 50-60 mph, the vehicle lost all electrical power. There is no warning when this occurs and the steering wheel also locks up. The vehicle is pulled over and restarted. The dealership replaced the ignition switch and fuel pump. The contact has been out of the country since the repair, last year; the vehicle has not been driven since repairs were made.
