Why won't my car start after fixing a broken serpentine belt?
Ok so first question is the starter rotating the motor like it should and it just wont start or are you turning the key without getting any results. If its not turning over id first off hit the starter solenoid with a soft hammer a few good raps may dislodge a stuck solenoid. Now if the motor is spinning but not firing up my first place id look is the distributor wiring unless it runs coil packs then i would guess that you knocked the wires off the crank sensor or maybe even broke the crank sensor. I am at a disability here not knowing what the vehicle make is., if it died while driving because belt fell off and you ran on battery till it ran out of power. ( a jump start is the ticket in that case ) Honestly im going with the crank sensor or crankshaft position sensor.being the root of your problem because if the belt broke it could easily take out the sensor as belt flew around the front of the motor. But check all your connections and research the crank sensor ..its usually a cheap and easy part to replace if its in a area where belt passes by it that makes sense as to your problem. Ok let me know a bit more info if possible. Dont give up the answer will come
I have a 2000 pontiac montana that stalls while driving and also if I let it idle in the driveway for 5-10 min
Do you have a check engine light/ service engine soon. If so , chek what code you have. otherwise check the egr valve and check if you have the correct fuel pressure. Most likely you will need to take it to a good mechanic to be able to diagnos the exact problem.
Why does my car just stop running all of a sudden?
I drive a 2001 Pontiac bonneville ssei. This seems to be happening everyday while I'm in rush hour traffic. I'll be driving along fine and all of a sudden it will just cut out. It's like the stupid thing has had enough of the traffic and wants out, honestly I can relate to that but would still rather it didn't cut out half hour to 40 minutes into my morning commute. I took it to a garage. They said it was the airflow sensor so I had that replaced but it still happened. Then the computer started spitting out an error code related to the crank shaft. The mechanic fixed that by replacing a crank sensor. But it's still happening and when it does happen the car is very difficult to start again. I don't want to take it back to the same mechanics because I'm starting to wonder if they are just charging me for non existent problems. I tried just putting my foot down on the accelerator the other day and the engine is like it's choking near the high rpm range. Any idea what could be wrong?
Why is my car shaking and the check engine light flashing?
A shaking vehicle AND flashing MIL ("check engine light") sound like the vehicle is misfiring on at least one cylinder. As @Anna Nguyen, @Brendan Sinclair, @Antoun Nabhan and others have said, it could be an ignition related problem. It could also be fuel-related. If one or more fuel injectors are clogged or dead, that would also cause a misfire in the affected cylinder(s). These are relatively cheap/easy things to check and fix.Other causes (which could be more complicated and more expensive) to fix include contaminated fuel, a bent intake or exhaust valve, a broken valve spring, a damaged piston/connecting rod, and on and on.I recommend getting a scan tool and checking the codes which are causing the MIL to light/flash and I also strongly recommend NOT driving the vehicle until the problem is fixed. If you continue to drive the vehicle as is, you will exacerbate the problem. Dumping unburned fuel into the exhaust due to a misfire will overheat and kill your catalytic converter. A more serious problem like a bent valve can eventually cause you to crater your engine (i.e.: completely destroy the engine).
What are some symptoms of a bad idle air control sensor?
Idle air control valves open to allow more air to "leak" into the intake, raising the engine rpms, or close when not needed. When your AC compressor kicks in or power steering is activated as you suddenly turn the steering wheel, the sudden drag on the drive belt will bog down the engine. These systems send a signal to the engine computer telling it they are active and it then signals the IAC valve to open, which increases the engine speed. Without this occurring, the engine could struggle, or die. The IAC valve can cause weird idle issues, mess with throttle functionality or cause the car to die. Sometimes they fail, get stuck or just get all carboned up. Sometimes people have success at cleaning them, but generally it is best to replace them when bad. Idle issues and even problems with the IAC valve may not be due to the IAC valve being bad itself. An idle issue does not mean the IAC valve is bad. It is best to pay close attention to how the vehicle is acting, and then communicate that clearly and as completely as possible to your mechanic. Intermittent problems can be very hard to diagnose. Details will help. Knowing more about the vehicle in question and its symptoms (in detail) will also help in understanding more about what it is doing.
What are the symptoms of a bad transmission speed sensor?
On some vehicles, there are sensors that function specifically for certain parts of the vehicle. Sometimes a bad speed sensor will mess up the function of the ABS brakes (causing them to overreact or not kick in at all, which usually creates a light on the dash), other times it can cause erratic speedometer readings and/or (for auto transmissions) cause inconsistent shifts and it shifting completely out of gear into neutral at random. Some vehicles it will do all of these things at once, but you should get a CEL (check engine light) or ABS light to show up on the dash if one of these things are becoming problematic enough to cause issues.
