Starting problem, need help
 

so i have an 04 coupe. resently installed an amp and pioneer avic d1 nav system. but now when i start my car it doesn't fire up right away. i changed the battery thinkin that was the problem. i've asked others and got different responses like it could be the starter solenoid or the coils or maybe the spark plugs. any body have this problem or maybe know what it could be.???

Need more info. What happens when you turn the key? Does it crank? Does it make a sound when it "stalls" before it starts? Anyhow, post a vid, even if it's a cheap one.

That sucks, good luck on fixing the problem.

I Had the same problem about two days ago, I recently got my system redone, and at first i replaced the battery thinking that was the problem, Only to figure out it was just a loose conection on the battery, its sounds dumb.. but its something alot of people over look, and iv had problems with it in the past as well, give it a shot, maybe save you some money if thats the problem? Hope it helps! Also it would be nice to get a little bit more information is this doesnt seem to fix it! Good luck!

spray down ur batt terminals with electrical parts cleaner and then tighten the terminal bolts. If the terminals wobble, u probs need new terminals. Check ur grounds also.

isn't this in the wrong section? lol umm yeah check your battery terminals, or maybe you have a loose starter wire..
