Hi,

I'm hoping someone can help me get this car started, please!
Instead of charging the battery overnight using trickle charge 4 amp
I used the quick engine start on my charger and I was able to start the car.
I understand this is not great for a battery to use this high amp instant start setting right?
So, one day I turned the key and nothing.
The starter will not turn.
I replace the battery and I get same result turn the key and nothing.
Can you help me identify if it possibly is the starter relay or fuse as opposed to the starter?
Like where is the starter relay?
I looked at the fuse box under the passenger side and I saw six or more relays, but the owner's manual doesn't tell me which one is a starter relay, and the fuses look okay. I pulled some and they look like they're not burnt course I should be testing with a multimeter which I can do.
I tried the old trick where you tap the starter with a hammer but that did not help. Any
Ideas to help me I would sure appreciate it!

Thanks!

It does sound like the starter relay is bad or the starter motor itself, (the hammer trick doesn't always work). Here is a guide to help check the relay and the relay location along with the starter wiring diagrams in the images below so you can see how the system works.

Do you have power at the starter trigger wire when the key is in the crank position?

This guide will show you how:

Please do, it's the way we can determine which side of the system we need to fix.
