Engine will not start. Battery was dead so I put a battery charger on it. Now the lights, dash board lights, horn and power locks works but engine wont start

THAT IS CALLED A DEAD STARTER OR NO CRANK . condition. period.
6 TO 10- CAUSES of dead starter.
WHAT WORDS AND GOALS (stages)
CRANKS (key to start/crank) or button start /stop pushed for start.
STARTS (loud cranking heard if engine is dead)_
AND RUNS (grins)
AND STAYS RUNNING, (bliss)
IN THAT ORDER ONLY, MY CAR PUSH STARTS SO GOES FROM PUSH TO RUNS,. JUST 2 STEPS(stick shift bliss this) M/Tbox.
when kid 15yo id park on a hill and do rolling starts. 3 speed manual box then./

turns over means zero, (turns = spins the starter spins and if lucky the engine crank shaft spins or turns and if lucky starts.
turns never means runs. ever. it is called RUNNING.
some call running at idle others (old) say engine ticks over.
yes heard all the slang but do avoid TURNS. and OVER.()roger over and out)

I just fixed my neighbors, the hood knows i diagnose cars for free, retired me.
her car the battery reads, 10.7vDC (truth here is only discharged)
2020 Nissan.
head lamps bright, proves nothing here. at all (unless fully dead lamps)
the battery pushes 5 amps to head lamp but can not muster 100amps to the starter. so starter is dead or after 10 tries. tiny clicks heard under hood.
I see dash lamp dim a bit at crank attempts, a huge clue there.

causes. are: in order.
including lies the BCM dash lamp tells. (key IMMO failure lamp glows)
a huge lie there, 2020 car, and I know why the 10.7vdc battery causes most computers on board to lie or be dead.


(fast forward, only here the battery is dead. and no DTC ever stored, after cure.

PCM OBD2 jack we scan the under dash jack, shows comms dead, CAN_bus dead (her car)
and expected by me. (took 20min after my full charge the cars electronics to work again, ) NOTE THE DELAY.
now your causes all and in order
battery lugs, loose or rusty or both
no battery ever lasted 17 years, so is on 2 or 3 battery now. or due for 3rd !!!!!


on the gals car above the tag top-o-bat reads 2020 see? I always look at tags.

1. battery lugs ok, and clean', battery not 7 years old or more.
2. battery voltage not 10v but 12.6vdc , rested 1hr. is it? if not charge it.we ran a 75ft extension from her house to street to charge it. with my charger.
3. or drag the battery to the work bench and charge it. or to any shop,say test it. this battery in hand,.. (way cheaper than any tow truck) or jump start it.
4. my load bank test shows hard failure, even no load, and BAD shows on dial loaded, but the battery in here car is good, and fails this test.
5. next up, charged, the IMMO key lamp must not show failing key,we tried both. keys.
6. starter relay bad.
7. PRNDL fails at start in Park and Reverse both, or just park. bingo SOLVED
8. the starter is bad, even hot wired it fails keys not near car.
9. simple failures here, just a starter not the 50causes of engine failure.

I only jumper cable start cars if in some kind of panic (stalled in snow bank)?
I charge the battery first with the tool called a battery charger.
this is more safe for electronics old relic chargers can push 20vdc and never is that safe for modern cars(computers max).
my charger is a smart charger.


this one is real good, 1hr charge and it is 90% charged, from 10.7v.

note that you never once said car can be driven? why?
job1, can you do job 1?
battery is going dead
if head lamps are dim its battery going dead, (not dash HEADs?)
notice is did not say battery was bad only discharged.

if engine starts is charge.battery lamp glowing.
i engine is dead, can crank it.
get a jump, call AAATOW
or find a loaned battery that is charged.
buy a battery charger and use it.

also cars can have phantom drains, as you sleep battery goes dead. (ask)

Your battery is dead, dead as a doornail. Charger 'er up, or grab some nice jumper cables, and crank 'er up.

try car to car boost-battery charger may not be working correctly or set on low amp charge -interior lights and dash may all light but battery may not be strong enough to energize starter have battery tested if battery good than check for power to the starter if power-- starter may be shot can remove also and have tested at most auto stores free if no power battery -wiring-or connection issue would need to test fuse panel-ignition switch and starter solenoid

This car might not get enough exercise. By that I mean there are things that are running all the time, remote entry systems, clocks, alarm systems. You may have a new battery, but it needs to be kept up to snuff. Sitting alone in the garage with NOTHING running, the battery will lose about 1% per month in ideal circumstances. As I said, your battery is powering all kinds of things while sitting in the garage so the drain is more than the 1% I mentioned. You may want to consider a trickle charger on this car if you are not able to drive it for at least 20 miles or more per week every week.

It seems your average mileage is just under 150 per week. I'm guessing you don't drive this car much on short trips, rather the bulk of your miles were highway on trips.

If I missed the boat on this question, please add a comment and I will try again.

Thanks for your question at FixYa.com

Try unhooking the battery, turn key on, leave door open, then connect battery, start engine immediately. The battery saver module thinks it's saving your power!!

I would start with putting a battery charger on the battery over night. If the battery takes a charge, then you may have ruined the voltage regulator in your alternator and the alternator is not charging the battery.

so my 06 cobalt keeps dieing and i have to jump it alot lately is it my alt or my battery

Make sure that the connections at the battery is clean and free of acid built up. Take the terminals of and clean them propperly

It could also be the ignition switch at the wiring end not making proper contact anymore, try and wiggle the ignition wiring if possible and see if there is any change in the status when the ignition is switch on
