I went out today to go to work and my car wouldnt start. I was just driving it last night! So I get in and twist the key and everything turned on like normal but when i went to crank it, nothing.... All of the electrical worked fine i just replaced my alternator and battery. I did just put on the frankencar intake but it drove for like 3 days before it did this. i didnt reset the ECU after I put it on if it matters because i dont know how. I know this was long but I need help. Thanks for your ideas in advance. James

 

Did you hear any clicking sound when you turn your key to start?If not check your starter wire and see if it's loose.If it's not then your starter prolly bad.

 

please search for this.

probably starter tho, have someone listen under the hood to see if they hear the solenoid engaging (a tick) when you turn the key and release it. if they hear that and nothing happens, have them bang the handle end of a screwdriver on the starter, that may loosten it up enough to get it goin. otherwise just pick up a starter for $130 from autozone. it is a pretty easy install.

 

Could be your starter or salanoid. Make sure around the battery terminal is clean and there is no corosion.
