My car wont start or turn over at all, I have done a little research and changed the starter out and replaced all fuses except for relays. The dash lights up fine and all other electrical works. I have tried to start the car in every gear still no luck. Brand new battery and I also tried to reset the car alarm to no avail. I am starting to get a bit frustrated because I am hoping to avoid giving and arm and leg to a shop, but I am starting to feel that is my only option. Could you please give me a few more steps that I may be able to take to assess the problem before I give in to the car dealership? Thank you and have a great day.

Try resetting your security system sounds like what it is doing. If no manual look online for you car on how to do it.

I don't mind talking to you. Sometimes when battery voltage is lost, some modules may need to be reprogrammed. I usually recommend people use a memory saver or a charger to keep modules awake when disconnecting battery for some reason.

Is the security lamp on the dash on or flashing after you try to start, key on, if so, sounds like a problem with security system? Can you check applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader. To me, a code reader, at least, is a basic tool.

The information I looked at shows your security system is starter disable plus probably the fuel injectors. Have you tried a different key? Have you tried programming your key or getting a new cut key then programming. Does your owners manual have any key programming information? I have not looked at your owners manual? I do have some programming information, not sure if it will help?

As far as testing we can usually get the starter motor to crank the engine, but, if is a security issues, it still will not start or start and stall. Any starter testing, make sure transmission is in park or neutral and functional parking brake is set. Safety is your responsibility, you do not want the vehicle to move when testing.

Thanks for the fast replies. Okay, I am inside the car now when I turn the key the whole dash lights up the theft light comes on on the first turn before ignition then once I completely turn the key to turn the car on the theft light goes off and all the other lights stay on as usual. I do hear what I believe to be a pump or something and I can hear what I believe to be relays going, but no turn over. The keys are original and the security system is original I cleaned the battery post/terminals no residue and got a brand new battery. I am going to buy a code reader later to see what pops up but last time the car was on there was no check engine light it had been sitting for two or three days, but when I went to get a jump nothing happened.
