I own a Honda CRV 2007 model. The battery just died, what type do I ask for? Will most dealers know if I simply state year make and model of the car I want the battery for?


THE DEALERSHIP OR AUTO PARTS STORES CAN FIND WHAT BATTERY YOU NEED.JUST TELL THEM MODEL YEAR TYPE OF VECHICLE.ENGINE SIZE AND TYPE OF FUEL INJECTION SYSTEM.HAVE ALTERNATOR CHECKED OUT WHEN YOU BUY ANOTHER BATTERY BECAUSE BATTERY JUST 3 YEARS OLD.THEY CAN LAST 5 YEARS.IF BATTERY FAILS TOO SOON IT COULD BE DEFECTED BUT HAVE ALTERNATOR CHECK.WITH ENGINE RUNNING ALTERNATOR OUT PUT SHOULD BE 13.5 - 14.5 VOLTS.

No fuel on fuel rail at engine,already replaced fue pump,and relay


Some cars, like ford and Jaguar have an inertial fuel pump cut off. I don't think Saab has one, but relies on the alternator instead. The fuel pump relay is only energized for a few seconds, unless the alternator has output. So a bad alternator will cut out the fuel pump relay. This is the way all Bosch fuel injected cars work.

2003 dodge grand caravan has started dieing at idle.


vans in that year all have throttle body injection and are preset as long as there is enough voltage from the battery could be a low battery charge or a bad sensor not telling the computor to keep fuel going at a stop if the check engine light goes on also when that happens if it doesn t bad fuel and a fuel injection cleaner might help and see what happens after that

My problem is my truck is blowing black smoke out the tail pipe and i dont know why i changed 3 ot sensors and a map air flow it is still doing it?


have you checked the coolant temp sensor? not the sensor for the gauge . the coolant temp sensor for the fuel injection. this sensor when cold tells your fuel injection system to add more fuel. in other words it acts like a choke in a carb. when this sensor goes bad it can send a signal constantly telling your computer the motor is cold therefor it needs alot more fuel than it realy does. also that sensor is tied into the 02,s. hope this helps.

1984 honda prelude battery on


Do u have the carbureted or fuel injected model? (both were available that year) The carb. model has a separate voltage regulator which is mounted on the right front shock tower. The fuel injected model is inside the alternator, under the end cover.
Have the alt. tested before u purchase a new one to make sure that's the problem. Most parts stores will check it for free. Be sure to disconnect the neg. battery cable before u start to remove it. Let me know how u make out. Curt

Car wont stay running even at a idle


It sounds like your alternator is almost done. Thats power distribution right there. If your alternator doesnt work, your car will run for a minute or two on battery power. Then it will kill the battery. If your car starts, its not the injection system, but you might need fuel injector cleaner to just run through your fuel injection system. To check the alternator, get someone to jump your car. leave the cables connected for about five minutes letting the car run. If it still dies, you need to clean your fuel injection system. If it doesnt die, its your alternator. A alternator costs about a hundred bucks.
