Top 10 2005 Saturn ION Questions & Answers

Plugs are under the coil pack. The black rectangle on top of the valve cover. Remove the plug on the drivers side, and remove the 4, 10mm bolts. Lift up the coil straight up. Will be fairly tough, and your plug wells are in there.

Buy 2 new generic brand bulbs and put them both in. I did the same for my daughter's car and was baffled when the other one didn't work.

A bit too late to help you I know, but this may help others. The problem is most likely a small lever arm microswitch that is oriented with the lever arm DOWN located just beneath the drivers side of the shifter. This is an interlock switch which prohibits starting the Ion in anything but park or neutral. There is nothing that holds the switch on the two posts that it mounts on and it is quite awkward to put back on. I strongly recommend using a small strip of double sided 3M tape on the side of the microswitch to prevent it from coming off in future. When this switch is not made, it will not allow the ignition switch to turn to the off position from ACC and it will not allow it to release the key. However, if you do not feel comfortable performing the repair, there is a 'secret access hole' under the steering colum, it is a small square door you can pry off so that you can put your finger in to it an depress a small round button that will allow you to rotate the key to OFF and remove it. And yes, you pretty much need three arms and have to stand on your head to do this, but, it will allow you to turn off the ACC and remove the key.

Their is a solution to the common saturn ion windsheild wiper problems. A new improved version of the wiper linkage is available and it has aluminum pivots instead of plastic. The plastic pivots were the weekest point of that linkage. I bought one oat this link and put it in myself. Awesome product

Actually there is an "I" on the shifter in a Saturn ION automatic. It means "Intermediate" It's just the shift position between "D" for "Drive" and "L" for "Low"

this is not a problem follow the steps below.Some might say it's a pretty straight forward job. The filter is under the rear of the car, just above your rear axle-it is secured by a single fastener, and has 3 "quick release" connections to the nylon fuel lines.
To Release Fuel Pressure:


Turn the ignition OFF.
Disconnect the battery negative cable in order to avoid possible fuel discharge if an accidental attempt is made to start the engine. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
Loosen the fuel filler cap to relieve the fuel tank vapor pressure.
Remove the cap from the fuel pressure service port.
Remove the engine identification cover nuts and cover.
Connect the SA9127E , or the J 34730-1A to the fuel pressure service port connection. Wrap a shop towel around the port while connecting the gage in order to avoid spillage. Refer to Fuel Pressure Gage Installation and Removal .
Caution: Do not drain the fuel into an open container. Never store the fuel in an open container due to the possibility of a fire or an explosion.
Install the bleed hose of the SA9127E , or the J 34730-1A into an approved fuel container.
Open the bleed valve on the SA9127E , or the J 34730-1A in order to bleed the fuel system pressure. The fuel connections are now safe for servicing.
Place a shop towel under the fuel pressure service port to catch any remaining fuel spillage.
Disconnect the SA9127E , or the J 34730-1A from the fuel pressure service port connection. Refer to Fuel Pressure Gage Installation and Removal .
Drain any fuel remaining in the gage into an approved fuel container.
Install the cap to the fuel pressure service port.

AND/OR PRIOR TO THAT...
a common "cheater" practise is to remove the fuel pump fuse and run the engine until it stalls, then crank it (wont start) for 10-20 seconds (1-2 automatic crank cycles) to minimize pressure in the lines.
ALWAYS WEAR SAFETY GLASSES AND DONT USE AN INCANDECENT (BULB TYPE) TROUBLE LAMP - FLOURESCENT ONLY!! (they've started more undercar fuel fires than almost any other source). So please be carful as this is a fuel job and do not start a fire.
