Why does my Saturn engine not start after Idle?
The engine ran great, idled smoothly (for a Saturn) and passed the state emissions test. But every now and then, the engine would not restart after a short trip. The engine would not stall, it just would not restart. It would crank normally but would not start until it sit for half an hour or so.
What are the symptoms of a Saturn’s series 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. This sensor has at least something to do with almost everything the computer does.
What causes a Saturn’s to slam into reverse?
This causes the car to “slam” into reverse and/or harsh upshifts, depending on which is worn. It will eventually destroy the line pressure solenoid, which will make for very hard upshifts. If left for a while, it will knock the input shaft nut loose, further worsening the condition of the shifts.
What are the symptoms of a bad timing chain?
Symptoms of a Bad or Failing Timing Chain. 1 1. Engine misfires or runs poorly. There are two ways to achieve valve timing in a combustion engine. The first is the two-gear method, which includes 2 2. Metal shavings found in the oil. 3 3. Engine won’t start or fails. 4 4. Check Engine Light is on. 5 5. Engine rattles while idling.
When to turn off the malfunction indicator light?
The DTC will give information about the detected issue. The OBD2 system can turn the MIL off automatically if the conditions for the problem stop to exist. After evaluating a system or component for three consecutive times without detecting the problem, the light can be turned off. But, usually the light remains on. What are the next steps?
Why does my PCM stall when I Turn on the engine?
The MAP sensor senses intake vacuum, which the PCM uses to estimate load so it can adjust the air/fuel mixture accordingly. If the MAP sensor isn’t reading right, the PCM will receive bad information and possibly add or subtract more fuel than it should causing the engine to stall.
What causes intermittent stalling in a car engine?
More Causes. One of the more unusual causes of intermittent stalling we’ve heard about is a defective vehicle speed sensor. When the vehicle stops moving, the PCM may not engage the idle speed motor (carbureted engines) or idle air bypass motor (fuel injected engines) so the engine will idle normally.
The DTC will give information about the detected issue. The OBD2 system can turn the MIL off automatically if the conditions for the problem stop to exist. After evaluating a system or component for three consecutive times without detecting the problem, the light can be turned off. But, usually the light remains on. What are the next steps?
Can a bad crankshaft sensor cause the engine to stall?
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.
What causes an engine to stall while running?
Intermittent stalling. Another symptom commonly associated with a problematic crankshaft position sensor is intermittent stalling. If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall.
Why does my car not start when I Turn on the ignition?
Starting your car becomes more difficult or it simply refuses to start. Unfortunately, you won’t see the source of the problem when all of a sudden the system fails. And repeatedly turning the ignition key, hoping that eventually the engine will fire up when it refuses to start, doesn’t always help. Most often, it creates more problems.
When to know if your car is hard to start?
At one time or another, the starter motors will wear out and suffer a breakdown. You should check the starter when absolutely nothing happens after turning the ignition switch, or the car turns over slowly with faint dash lights. 5. Failing Solenoid
What causes a car to struggle to start?
It produces electrons through chemical reactions, but the process slows down in low temperature. As a result, it generates fewer electrons and supplies less than sufficient energy to the starter. This obviously cause your car struggles to start. The same issue can occur in the case of a worn out battery.
What’s the problem with my Saturn’s series?
I have a 95 Saturn s-series with trouble starting when cold. Sometimes it take 5-10 minutes to get it started. When it does start it is all you can do to keep it running. I have had it to 2 different repair shops spending way too much to not have the problem fixed.
Why does my 1996 Saturn SL2 not start?
The battery in my 1996 SL2 discharged because the car was sitting for several months unused (I know, I know — I should have disconnected the battery!). So I recharged it (pretty sure, anyway). Now the lights come on, etc. but when I turn the ignition the car cranks for about 1 second then stops cranking and there is a loud rapid clicking noise.
Why does my Saturn 104k not start up?
My ’97 Saturn (104K) starts well in the morning. I drive home everyday about noon. When I try to start it, it cranks, and will eventually start, but it takes a good 8 to 10 seconds to get it going. The weather is hot when I have these problems, not sure if this has anything to do with it. Any thoughts?
Why is my Saturn’s series making a clicking noise?
Now the lights come on, etc. but when I turn the ignition the car cranks for about 1 second then stops cranking and there is a loud rapid clicking noise. I’ve seen this symptom before in other cars but I can’t remember what they mean. Can anyone help?
Why does my car say it has a bad starter solenoid?
Problems that might cause your car to act like it has a bad starter solenoid can include: Bad battery – If the battery voltage is low it will be unable to provide enough power to start your engine. Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem.
What’s the difference between a starter relay and a solenoid?
Most often, a true starter relay is a small black cube plugged into an electrical fuse/relay box in the engine compartment, whereas a starter solenoid is (in most cases) attached directly to the starter on the engine (although it is sometimes located elsewhere in the engine compartment).
When does a solenoid need to be replaced?
Starter – Some solenoids are mounted to the starter, but some are located directly inside the starter housing. When this is the case, it may be necessary to replace the entire starter when the solenoid goes bad. Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient.
Can a bad solenoid cause a car to not start?
If the starter engages but does not disengage when you let go of the key, the solenoid is likely bad and the starter may suffer significant damage as a result. 6. Sometimes your car starts, sometimes it doesn’t. Intermittent operation can be a sign of a failing starter solenoid. Other issues that present a bad solenoid
Where is the starter solenoid located on a car?
Most often, a true starter relay is a small black cube plugged into an electrical fuse/relay box in the engine compartment, whereas a starter solenoid is (in most cases) attached directly to the starter on the engine (although it is sometimes located elsewhere in the engine compartment).
