Plug a suitable diagnostic device into the obd port and select the section dealing with fuel trim and read off the results - I can't help more than that because I don't have a complete understanding of how to interpret them.
I think the fuel trim is the difference between the expected injection duration and the actual duration. I also think it is of a somewhat general usefulness, providing strong clues of faults elsewhere as well as possibly the injectors themselves.

SOURCE: 2004 Saturn Ion transmission

It should be on the drivers side and it looks like the oil dipstick. Usually the top of the handle is shaped like a " T ". Most of the time it will be yellow and say trans on it. It may be lower than the oil dipstick. Good luck.

SOURCE: 2006 saturn ion door locks and trunk pop wont work....

The remote won't ework because the problem is in the vehicle. Just for test purposes and possible remedy. Remove and clean the negative battery cable. Ensure a clean , tight connection. Then find the body ground. Yhis ground is locted usually at the top rear of the engine. .I's a snall stainless steel strap bolted to the engine and fire wall, This must olsobe clean with a good contack. Might as well clean the + cable and connection on the battery while you are there. Good luck and keep me posted olease. Good Luck, Ned_

SOURCE: 2006 saturn ion dome light goes on by itself and

When this happened to mine it ended up being a bad door switch. The alarm, dome/map lights and electric door locks are all connected to the door switches. It cost $65 for diagnosis, parts and labor at Saturn of South Burlington VT

I have a 2006 Saturn Ion 2.2 125,000 miles engine light came on then wouldnt start finally got it to start took it to auto parts store and checked it said to lean bank one i have changed fuel filter and...

Doesn't sound like you would know how to do a fuel pump pressure an flow testing , suggest you take your vehicle to a qualified repair shop that has the proper diagnostic testing equipment .
Rather then guessing an replacing parts you don't need . (fuel injector's ) Could be low fuel pressure , a bad MAP or MAF sensor. What are the fuel trims showing ? short term an long term fuel trims . Are the O2 sensor's switching normally ?

Where would the fuse or relay for fuel pump be located in my 2003 ion

Look in the interior fuse block. It is located on the drivers side of the center counsel, just to the right or where our right leg would be. You will need to remove the trim panel. The fuses will be labeled on the inside of the panel.

2006 Saturn ion 2 won't start.

You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Had to replace fuel pump in 2006 Saturn Ion... it's only THREE!

i just had the same issue . . .I have been having starting problems with my car (2006 Saturn Ion) and smelling gasoline. It turns out the hose connected to the fuel pump was cracked and leaking gas. The mechanic said that this is a safety issue and should be recalled. He feels that the one hose is not connected and harnessed properly and the vibration to the hose eventually caused the crack. I googled "Saturn 2006 Ion fuel leak" and several other people have had the same issue. What is also the major problem here is that the hose is configured with the fuel pump itself. So, the entire mechanism had to be replaced. It cost me 700.00 for a cracked hose because the fuel pump had to be replaced and my car only is 46,000 miles. This is a major safety issue. I drove for 2 weeks with a car that was leaking fuel. Saturn must know about this and is waiting for the same situtation to happen, but for the car to blow up instead. PLEASE IF YOU ARE READING THIS CAUSE YOU HAVE THE SAME ISSUE . . . . contact the office of defects and the NHTSA . . .This is a saftey issue and a recall needs to be in affect . . .

Saturn ion fuel pump

Misnikie32 . .. I just had the same problem around the time you figured out your problem and I just got it fixed yesterday. For almost 3 weeks I had starting problems and I constantly smelled gas. The problem is a safety issue and the car needs to be recalled. The hose that is connected to the fuel pump is cracked. Since the hose is incorporated with the fuel pump, the entire mechanism needs to be changed. Look at spending about 700.00 . I informed saturn and told them my life was at danger. Please contact them on their website and goto your state's attorney general and launch a complaint, as well as the office of defective investigations and the NTSAB (google them). This needs to be brought to their attention and all owners of this car. I googled this and many other people are having this problem. Some are even on this forum. PLEASE DO THIS ! ! ! !
