SOURCE: 2002 BMW 325i - engine won't turn over / start.

take battery back get a new one or have it tested. like auto zone or a parts store even wal-mart now. If this battery was just dead and needed charged. Then sounds like to me you have a bad alternater. you can rely know if you can get the battery charged up and get the car to start. and while the car is running pull the positive connection of the battery if car dies bad alternater .

look for bad grounds in the ignition circuit.the corrosion is creating a voltage drop,but time and heat decrease the resistance..

SOURCE: engine management light comes on and when its sat

this is where it would of payed to just get it diagnosed. By your symptom description I would never of suspected those two parts as being the cause. With the light being on the code would of told you what cylinder is misfiring. This makes it easy to diagnose. Its either time for spark plugs, or you have a dead miss which could be a bad coil or injector or vacuum leak, or a injector that is clogged and needs cleaning or replacement.

Really bad luck. Do you have a obd2 fault scanner? that may help. If this still could not detect the problem, send your car to a local garage. Good luck!!

00 Explorer 4.0 ohv v6. If cam position sensor fails will it cause, #1 engine to die at hwy speed 60mph? Also upon trying to restart, it cranks very fast, is that poss. cam sensor failure too? Thanks

No, to the second question- sensor won't make it crank any different. Faster than normal cranking often means a broken timing belt -less friction with the valve train not moving, so engine spins faster. But you have a timing chain, right? Any engine noise when it quit at 60mph? You could watch some valve action through the oil filler cap while the engine is being cranked, to make sure the timing chain is still intact.
If all is good, check for spark and gas to the engine. If stopped while running, it could be a failed fuel pump or a problem in the ignition system- cam or crank sensor, ignition coil, ignition control module, some of the things to check if no spark.

2004 chevy 2500 hd deisel, wont start, canged fuel filter about 3 months ago, started today and ran for about 10 seconds then shut off. Haven t been able to start it since??

2 items that will put you back on the road. The glow plug controller When you turn the key on do you hear it. Its on the left rear of the engine above the rocker cover to the left of the turbo charger the glow plus is a assistant to aid in starting, There are two type of controller its either a rely or a solid state, Cycle the key it should come on for 2 seconds. cycle the key again. then start it,if it start get a glow plug if it doesnt start are you willing to use either(its called instant start) use the one for diesel. did it start and stay running. if it stays running glow plug control is needed. Now if it didnt stay running and shuts right of youll need to replace the cam sensor, the cam sensor is located in the right side of timing cover behind the water pump pulley. They are plaque with damage. inspect the cam sensor and the connector for damages, If the camsensor rattles its defective. This cam sensor are failing left and right oh by the way carry an extra one the are common failures

I have a 97 dodge ram w/5.9 if it sits i can start and drive it until i shut it off. then I have to wait around 24 hrs before it starts again. It doesn't have spark coming from the coil when it doesn't...

A 'hot' fault is usually associated with an electrical failure of the crank and or the cam sensor. The crank sensor sits near the starter motor on the edge of the flywheel housing. The cam sensor is near the end of the cam shaft on the front (end nearest cooling fan) of the engine. Fundamentally when either the crank or cam sensors fail the engine loses track of when to spark and when to inject fuel respectively. I would change the cam sensor first as a) it the easiest and b) is most often related to hot start failure. his will cost about $30 and take about 20 minutes. If this does not solve the problem move on to the crank sensor. This is about the same sort of cost but will entail a bit more getting at and so budget about 90 minutes. When working on either sensor make sure the engine is cool, getting scalded is no fun.

If it has a code for loosing the crankshaft position sensor signal, I would certainly start looking at that before venturing into the fuel system. Cam and Crank sensors are a common failure item for Nissans of that era. Nissan actually redesigned the sensor and i think they performed a recall on some vehicles. They are fairly inexpensive and easy to replace. I believe they run about $40 each. Because most people don't have access to a powerful scanner or a digital storage oscilloscope to verify the failure I recommend replacing the cam and crank sensors at the same time.

1995 lesabre doing same thing

3.8 litre engines have wiring issue to the crank and cam sensors the insulation breaks down on heavy oil soaked wiring thus not protecting the wires from shorting to ground. when they short no pulse signal is present and car will shut off or not start. Simply cut the old wires and replace with new ones and if possible route the new wires around the front of the engine and then plug them into the sensor. Add split loom to help protect your repair. good luck

Someone please help!!!! I have a 2000 buick

A cam sensor only helps the computer when cranking and should not make it cut off. Most cam sensors do not go bad, but he magnet on the timing gear will deterorate. To fix that the timing cover will have to come off. Replace the crank sensor they get hot and stop working. When they cool down they will work again until it gets hot.

Sounds like a sensor is breaking down under heat of engine.
Try the Crank sensor (under the alternator at front of engine with a 2 pin multiplug attached. Or the Cam sensor (more likely) placed behind the oil filler neck and looks the same as the crank sensor. Breakers should sell you these for approx £20 each.
If no joy let me know.
