When I attempt to start my car it will not crank

We have a 2006 Chevrolet impala LT 3.5liter. Turned car on lights flickered, so shut off car now car wont start and check engine light on. If I jump the car it turns over and works fine. I took battery to autozone said it was good and fully charged it. I put into car wont start, so jumped again ran fine. Took car to autozone and had it scanned the codes they gave were P1516, P1682, P0689, P2176. Please help

Car wont start, have tried charging battery, replacing starter, still wont start, when you attempt to start the vehicle it doesnt turn, you just hear a click, click sound

Today I installed a new radio in the car. I unhooked everything including the radio and I had to leave so I hooked the battery back up and proceeded. Once I got back home I unhooked the battery again and continued where I left off. Long story short, afterwards, the car will turn on, but it won't start. I've been trying to start it all day. It's been about 6 hours. I went to check on it and it didn't start again, but I noticed the reverse lights were on. Also when I turn the hazards on, the lights in the car get dimmer and brighter. Is this a battery problem or something more serious?

About once a week the ignition will not make connection. The lights, etc. Work fine, but it won't start. It is like when you don't have your foot on the brake or the transmission in park. After about 10 minutes of trying it will all of a sudden kick in and do fine. The problem will not reoccur for about 10 days or so.

My car needs a boost almost everytime I cut it off once it is started it runs good. But When I try to restart it sometimes it will start, but when it doesn, t all interior lights radio, windows and battrey operated things work it will click as to turn over but want start. I had the baterry checked and its good, I had the alternator checked and its good what could be the problem

Battery good. It does this on occasion and it will start with no problem as though nothing is wrong. Bo

Hey, the same thing happens to my 05' Chevy Impala Base 3.4L time to time. Usually when the engine is hot. I took it to get an oil change yesterday and the car would not start. The battery was replaced two days ago so that could be ruled out. Plugs were done a few weeks ago. They checked to see if the fuel pump was kicking on and it was. The engine was cranking and seemed as though it was about to fire up and it would just die. The mechanic held down the throttle when I turned the key and it would run until he let off the throttle and it would just shut down. It really had him confused as to what it was. I've read alot of people have been having this problem. Could it be a gasket that is leaking air or something or maybe something to do with the compression? I sat there for about an hour of trying and then tried it again and it fired right up. Talk about craziness.I think once the engine cools it's fine. Also once it is started it never dies, even when it is idling. Any input would be greatly appreciated.

Tried to start the car, battery light came on and there was a grinding (?) Noise. Sounded like it was coming from the dash. Haven't tried to start it since.

Engine won't start. No clicking noise that I would expect to hear if dead battery. Also, lights do not appear dim. Engine sounds like it is trying to turn over, but straining and even comes to a complete stop. Loud static-like sound from speakers, even though the radio is turned off! I will replace battery tomorrow (it's about that time anyway), but I am worried that it may be an electrical problem, the starter, or that the engine has seized up (needs oil change, but level appears to be at least half full).
Thanks for your help.

This vehicle has been well maintained and is driven 500 miles per week with no prior indications of problems. She just suddenly laid down. Battery is good, (reading 14 amps); ground is solid, all fuses, in all four boxes have been removed and visually verified as good. I have replaced the ignition switch. The problem is as follows: When key is inserted and turned, most dash lights do not come on. The gauges make several attempts to power up but fail. Rhythmic clicking from multiple relays, but nothing from starter. Despite good battery, the headlights will not activate and the horn sounds like a strangled goose. What am I missing or what's the next step?
