Please Help!!

My problem is that my motor will no longer start. At first I posted a thread on here about my motor struggling to start, but just recently it just stopped. When I say "start" I mean the engine wont spin or anything. My setup is AEM SRI,AEM fuel rail and regulator, NGK wires, and DC headers. I'm guessing that its my starter but I dont want to assume and spend the money to get one because I am on a real tight budget now. Another member also mentioned that it could be that my fuel filter is dirty? I dont know, but please help!! this is my only car that I use to get to work and I need it fixed ASAP! Thanks. Late.

just take it to autozone or something and get your starter tested. i had this problem on my previous car where it wouldnt start and i had to replace the starter

check your fuses?

is there a click when you turn the key or is it silent?? Your best bet would be to have the starter and battery tested at auto zone. also do you have an alarm on the car?
