Electrical? engine light on sometimes - had light checked and was told fuel sensor problem (which it prob was because the fuel needle only moved after filling miles down the road). Replaced sensor...engine light still occasionally pops on. dome light stopped working-already changed bulb-worked 1 week and automatic door locks do not work immediately and steering is sluggish when first turning after starting and lower dash lights won't come on unless knocked with fingers. what's happening?

Experiencing random stalling issues with your 2006 Saturn Ion can be frustrating. There could be several potential causes for this problem, and it would be best to have a qualified mechanic perform a thorough diagnosis. However, here are a few common issues to consider: 1. Faulty Ignition Switch: A faulty ignition switch can cause intermittent loss of power and result in the engine shutting off unexpectedly. If the switch is worn or damaged, it may disrupt the electrical connection to the engine, causing the stalling. Consider having the ignition switch inspected and potentially replaced if necessary. 2. Fuel Delivery Issues: Insufficient fuel supply or a malfunctioning fuel pump can lead to engine stalling. Check for fuel-related problems such as a clogged fuel filter, a failing fuel pump, or issues with the fuel injectors. A mechanic can perform fuel pressure tests to assess the fuel delivery system. 3. Electrical System Problems: Issues with the electrical system, such as loose or corroded connections, can disrupt the power supply to critical engine components, resulting in engine stalling. Have the battery, alternator, wiring, and connections inspected for any signs of damage or poor connectivity.


4.Engine Control Module (ECM) Malfunction: The interruption of power to the computer, as indicated by the check engine light, could suggest a problem with the ECM itself. It may be necessary to have the ECM thoroughly inspected or potentially reprogrammed or replaced. 5. Sensor Malfunctions: Faulty sensors, such as the crankshaft position sensor or the camshaft position sensor, can cause intermittent engine shutdown. These sensors provide crucial information to the ECM for proper engine operation. If any of these sensors fail or send incorrect signals, it can lead to stalling or engine shutdown. It's important to have a qualified mechanic perform a diagnostic scan and conduct further testing to pinpoint the exact cause of the stalling issue. They can use specialized equipment to monitor various systems, retrieve error codes, and identify any underlying problems. This will help in accurately diagnosing and resolving the issue with your Saturn Ion.

Without testing we'd only be guessing . Hooking up a factory or a professional type scanner , an checking engine sensor data parameters , checking fuel pressure an flow , basic electrical system testing - battery condition , charging system output testing etc.... GM did have instrument cluster problems , late 90's - mid 2000's . Stepper motor's inside the cluster that drive the gauge needles , an silver migration . Can cause all kind of electrical issues , battery draining over night , starting problems ,warning lights coming on etc....
How to repair GM Instrument Cluster Speedometer Gauge Stepper

Your best bet , take your vehicle to a qualified repair shop.

either have an autoparts store check it or someone you know with a code reader
http://engine-codes.com/ this website helped me alot in figuring out codes

The blocked fuel filter is incorrect, fuel is whats causing the black smoke. I would check for a stuck or bad EGR valve, sometimes you can clean them sometimes you just have to replace. I bet it really sucks trying to keep it running at a stop or traffic light.

Check the fuel pressure, check ignition fuses and injecter fuses.Scan for codes, may be a timing belt bad.

remove the sensor then with a meter set to the lowest milliamp setting connect the meter to the two wires on the meter and move a spanner across the head of the sensor and see if the meter needle moves ,if it doesnt move renew the sensor

I have same ****

check your fuel pump relay 

Hi, It seems most of your prob could be from worn engine mounts. Have a helper shift from 1st to reverse and see how much the engine moves. [at a fast idle, brake held firm, stand to the side]
This will not cure the prob! Yet My thought is that you will now need to check all the wiring that was involved in this movement.Hope this helps you! Frankster016

It can be also the oil, so chack it...
