I have a 2005 Nissan Altima 3.5 SL. The car was running fine yesterday. This morning, my sister went to crank it up and both the tcs and abs light came on. The car would sometimes go forward and sometimes go backward. She then cut the car off. After trying to crank the car, the headlights would flicker and the car would not start. The car also makes a loud humming noise but that may be due to a cold start.
How old is the battery?
How clean and solid are the battery terminal connections?
The first thing to do is to take a look at the battery…
“cut the car off” ?
“crank the car” ?
what do these mean?
Many people use “car” instead of “engine” when describing these situations, so I believe that the OP is referring to cranking the engine, and to the engine “cutting out”.
Or, maybe not…
As VDC driver said, check the battery…age and connections.
Battery connections are the first place to begin when you have a “No Crank” situation. Even
if you have a new battery, if the connections are loose, dirty or corroded, you will not be
allowing the full flow of current to pass thru the connections. The connection may be
enough to turn on the lights, but not enough for the huge flow that is needed to operate the
starter. This is where many people say that they know the battery is good….”because the
lights come on”. This is no more a battery test than licking a 9volt battery. It only tells you that there is electricity…not how many volts or the amperage that flows from the battery.
Jump starting may have wiggled the terminal just enough to allow the current to pass and start the engine, but tomorrow you have the same problem.
First remove the cables from the battery and use a wire brush to remove any corrosion and dirt from the battery posts and the cable terminals. There is a tool with a round wire brush for this purpose, found at any auto parts store for less than $10 http://shop.advanceautoparts.com/p/kd-tools-terminal-battery-brush-kdt201/25980576-P?searchTerm=terminal+brush.
Before connecting the cables, apply a coating of di-electric grease to the battery posts this will keep oxygen away from the connection so that it will not corrode as fast.
It is just as important that the other end of the cables also have a clean connection. Remove the positive cable from the battery again so that you do not short anything out. Follow both cables to their far ends, remove this connection and wire brush the connection and the cable terminal clean and retighten these connections.
If there was work done recently, there may have been an “engine to body” ground that was not installed following the work. These grounds normally run from the rear of the engine to the firewall and are uninsulated and most are a braided wire. If any of these are found unattached…reattach them.
Remember….this is not a “Sherman Tank” don’t over tighten the connections.
Under what conditions did the car “go forward” then “go backward”?
“Cut the car off” means turning off the ignition. “Crank the car” means starting (or attempting to start the engine). You need to get out more BillRussell.
You’re sister probably did a good job on your car! But seriously, check the battery first.
