Ok I have a 2000 Honda accord it won't crank won't do anything it's like its lost all power what could it be

 

First check for codes.

 

It won't give a code it's like it's blocked

 

I've had it on the battery charger for a whole day went out this morning and the lights looked like they were getting dimer they were flickering could it be the battery

 

Check the battery cable for corrosion. Clean is necessary. If that does not work then the battery will need to be checked. I think the battery is bad. That is a guess.

 

Replaced the battery had the starter checked said it was good and still nothing I'm at total lost to what it could be

 

bad ground? remove and clean even if they look ok.

Where's the ground wire

 

Makes a clicking sound when I go to try and crank it but still won't crank all lights on dash come on but won't start

 

You can't test a starter with a tester. If the starter cranks then the starter is good, but when it doesn't crank the only way to test the starter is to manually jump the solenoid.

However, first you want to disconnect the connector that is connected to the starter, Test for voltage on the connector while someone cranks the motor. If you get voltage then the starter is bad. If you don't get voltage than something else is wrong, possibly the ignition switch or if you have an aftermarket alarm it could be the starter ignition kill function that is bad.

It's more likely the starter is bad.

 

This has happened to me on my 97 accord. I had disconnected my battery and when I reconnected it, it wouldnt start. It would just click a single time and never attempt to crank. I eventually traced the click noise to an aftermarket alarm/keyless start dongle near my fuse panel.. I never even knew this was there.. After a bit of research, I found there was a "valet" button I needed to press and hold or something like that.

 

Yea I wouldn't even know where to start to finding that but however there is a after market alarm on my car

 

For me, the dongle was wires next to the fuse panel and I traced the wires back until I found that button. Let me go snap a couple pics for you.

 

Ok thank u so much

 

I figured a video would help a lil more than pics. Our cars are different but hopefully this hhelps.

Had your battery died at some point before the no crank occurred?

 

No I had took it out to put in a different car to see of it would crank it did put back in my car and had trouble since

 

Yeah I determined mine has a lockout on it, in case someone attempts to bypass the alarm by disabling the battery, etc. So removing the battery, or letting the battery die makes the vehicle not crank. You need a special key fob or in my case, a button, to deactivate the alarm system. Sounds like you might be having the same problem.

I tracked that dongle down by listening for the click. Good luck!
