2004 Sebring LXi, 2.7 V6, motor won't start after a dead battery. On first attempt to Jump Start the motor tried to move once, then a loud trrrr noise, like banging 4-5 times/ sec. Now the motor is not even trying to start, only that noise is present and the Check Engine light is ON. No DTC though. What could be the possible reason?

Either a weak starter or battery is causing the start issue. As for running hot, not a related problem.

battery is dead try to pair of jumper cables connected the same way as a single jumper cable this increases the cross sectional area of the wire causing more current flow

You say the battery seems dead

I suggest that you test it,you should also
know if it is at least 5 years old & would expect it to go dead

That said, those things you need to know before you
ever attempt to jump a battery

If it isn't capable of taking a charge,then your
basically creating an unsafe act & bad things
could happen to that battery & you

If the battery is dead & the vehicle is running
on the alternator,then the electronics won't work
& you go 10 mph or not at all or worst.

The lack of power could be any number of things
Work on the battery issues,then continue on

Obviously your battery needs acid soln to work. Give it for recharging & if the plates are still good it will work else replace it.

check battery out and battery connections real close

Replace the battery first! That acid will corrode everything it touches. Once the battery is replaced, you can test if the alternator is working properly.

first as a rule of thumb, check your fuses
then check for spark at the spark plugs
then check for fuel at the fuel rail
you should eliminate some of the system at this time

check the fuseable links under the hood on the drivers side fender well you will find on that has blown into internally

I had the same problem with my 1999 Chrysler Sebring 2.5L V6 Convertable. It started stalling at intersections; would lose RPMs' and die while driving it; and would not start unless it sat for a few minutes. Once it started, you'd have the scenario start all over again...

I hadn't kept up my maintenance schedule like I usually do, so I did the usual; I replaced my spark plugs and wires, changed the oil and filters, ect...

Finally, after it doing the same thing and wasting a ton of time and frustration on the side of the road, I took it to a mechanic that put it on his $9,000 diagnostic machine. The verdict; CRANK SHAFT POSITION SENSOR!

The Haynes Manual will tell you wrong on its location for the 1999 Lxi 2.5L V6 convertable; it is NOT LOCATED BEHIND THE BATTERY TRAY. The crankshaft position sensor is actually located about 4 to 6 inches below the distributor, which is about dead center of the motor, on the transaxle housing.

You do have to take off the tire and the skirt cover to get to it. I had to purchase two long socket extensions just to get to the bolt that mounts the sensor to the transaxle housing; but it was well worth the 20 bucks...

All in all, it took me three hours to find the damn thing, and then to figure out what I needed to take the old one off and get the new one installed.

The $65 dollars that I spent to find out what the problem was is worth it....

Now, the car runs better than ever....
