What to do if your Saturn SL has a leak?

When the air conditioner in your 2000 Saturn SL starts blowing hot air, you likely have a freon leak. Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant.

How does the crank sensor work on the ignition module?

When the engine starts to crank, the crankshaft position sensor starts to produce and send its signal to the ignition control module (ICM). The ignition control module upon receiving this AC Volts crank signal, converts it into a DC digital signal and sends it to the ECM.

What causes a crank sensor to not start?

Now, if the NO START is caused by the ignition module or the crank sensor, usually the ignition coils will not fire any spark at all. Therefore, the second symptom that leads you on the path of a BAD ICM or crank sensor is: No spark at any of the ignition coils.

Where is the fuse on a Saturn ignition?

Open the fuse panel under the steering column by turning the knob on the fuse panel counterclockwise and pulling down on the cover. Locate the fuse for the starter in the fuse panel using the fuse diagram on the underside of the fuse panel cover. Remove the fuse using a fuse puller in the fuse box.

What happens to spark plugs when fuel pressure is low?

A low-pressure fuel system will destroy the spark plugs that ignite the fuel in an engine’s cylinder. If by chance you are replacing them and you find they are worn out before their time, you might be looking at a problem with your fuel system. Fortunately, the fuel system in a car requires only needs minor tweaks.

How can I tell if my fuel pressure sensor is correct?

First, make sure that the fuel pressure sensor is correct. Check the fuel pressure with a manual fuel pressure gauge to figure out if you can find any problems with the pressure. If so check fuel pressure regulator.

Where is the ignition switch on a Saturn?

The problem was due to the original ignition switch which is a $50 part from Saturn. The ignition switch is located on the back end of the ignition lock. The ignition switch sends a code that is generated in the ignition lock to the body control module (BCM). It is a part of the Passlock2 system on the 2004 Saturn.

What are the problems with my 2004 ion2?

Need some confirmation. Having intermittent starting problems with my 2004 ION2. Insert key, turn on, lights come on but no turnover. Sit a few minutes, turn on, tries to start but dies as if no gas, or get a turnover and that’s it. Sit another couple of minutes, turn on, lights, no turnover.

What does the PassLock system on a Saturn do?

The Passlock system is intended to prevent a worn (worn keys use to be about to start any of the earlier model Saturns without any security system) or incorrect key from starting the car. If the proper code is not sent then the BCM will shut down the car for up to 10 minutes.

What happens if you have an ignition switch problem?

Ignition switch problems can also cause issues on the road, such as unexpected shutdowns or electrical problems. To be sure, ignition switch problems are no fun, especially if they’re stopping you from getting to work or school or play. If you’re having an ignition switch problem, taking care of it right away will prevent you from being stranded.

What to do if your ignition system is not working?

Most causes of ignition system problems can’t be corrected by a non-expert, but there are a few things you can do to discover a problem’s location. It primarily involves checking for sparks on the spark plugs and ignition coils. Remove a park plug wire from the plug and connect it to a spark tester.

How is the ignition switch connected to the car?

The ignition switch itself is connected to the ignition cylinder by a shaft or lever. Inside the ignition switch, several contacts connect vital electrical systems needed to start and run the car.

Can a faulty ignition switch cause a car to not start?

There is a component inside the dash and linked to the ignition switch that sends a signal to the starter motor allowing the vehicle to start. If you are experiencing problems with your ignition key or switch, you may need a simple key reset or you could have a faulty ignition switch that needs to be replaced.

What should the circuit resistance be on a Saturn Ion?

There’s an open in the circuit resistance is above 200 ohms and a loose terminal or a faulty module if below 200 ohms. Measure the resistance between the crankshaft position sensor’s terminals A and B. (Disengage the DIS module’s five-pin connector first). The resistance should be 700 to 900 ohms.

When does a Saturn’s series engine fail?

The aftermarket replacements have a quality problem; best bet is to find a low mileage junkyard replacement or order the OE part (~$70). Not hugely common, but still a recurring failure. They usually fail when the engine is hot. You’ll be driving along, and suddenly the engine dies, and won’t restart until it cools.

What kind of spark plugs do Saturn’s series use?

Most copper plugs fit this description. Narrow fine wire electrodes almost always cause problems, usually a p0300 and running like the car needs new plugs. The easiest thing to do here is just use the OE spark plugs, they’re inexpensive and just work. NGK BKR5ESA-11 (DOHC) and BKR4ESA-11 (SOHC). These have a higher than normal failure rate.

Why does my Saturn’s have a toaster head?

Some people run a 60-40 antifreeze-water mix as a preventative measure. The key symptom is massive oil contamination in the coolant, to the point where it has the consistency of a chocolate milkshake. The head is toast and the coolant system will need to be flushed thoroughly. This is only a problem with the SOHC engine.

Where is the starter fuse on a Saturn?

What causes the solenoid on a Saturn to come loose?

According to complaint reports from car review websites concerning the Saturn, the starter solenoid can come loose from the mounting bracket, which causes the contacts to not make a connection.

Why is my Check Engine light not turning on?

Here are the four most common symptoms of a bad ECM computer: There are many reasons your Check Engine light can turn on. These range from emissions problems to faulty O2 sensors to problems with the ECM. If your car seems to run fine but the Check Engine light won’t turn off, your ECM may be at fault.

Why does my Saturn make a clicking noise when I start it?

When the contacts in the starter solenoid burn, the solenoid burns out or damages the starter motor. Most of the time when the starter solenoid or starter motor is damaged, the Saturn owner can hear a clicking noise when the ignition switch is engaged.

Are there any problems with the Saturn Vue?

In many cases drivers have experienced problems with the dashboard gauges, including the fuel gauge and engine temperature gauge, which may display incorrect information or fail to function at all. This problem can be a result of an electrical problem elsewhere in the vehicle and can be difficult to diagnose.

According to complaint reports from car review websites concerning the Saturn, the starter solenoid can come loose from the mounting bracket, which causes the contacts to not make a connection.

Why is my ignition module not working properly?

It’s also possible the circuits may be critically damaged by overheating if the problem is not addressed after the first or second occurrence. If you cannot start the car, you need to test the ignition control module using a light timing tester to check the output of the module.

Are there any problems with the Saturn’s series?

Saturn experimented with making these out of plastic, it was a huge failure. ALL of them failed, if you still own one of these cars and it hasn’t been replaced, it has failed. Symptoms include hard starting, rough idle, temperature gauge not working, awful fuel economy, poor performance, and stumbling, among many other things.
