Ok so I’m trying to track down what this problem is it has to be a short somewhere but I’m out of places to look and need help. On friday after driving on the highway for about an hour with no problems I got off the highway and was cruising I put my lights on they were fine for a bit then they blew the fuse. (interior light and brake run light 15amp 3rd up on the right side drive side). After a little while longer the fuel pump start acting really bad like i was running out of gas. At the time i thought it was a bad pump and a short somewhere in my interior. I think its fuel related i change fuel filter and top up on gas. Car seems to be running fine I drive it home on sunday carefully with no problems. Today i go to get 15amp fuses. Car starts fine and pulls hard appears to be no fuel delivery problem. I stop at crap tire get fuses get back and start it up again still no problems car still pulls hard ( at this point i’m trying to find a problem with fuel so I’m really stepping on it when i can). Now I drive a little further and i stop in a parking lot with the car idling and i put in the 15amp fuse for the interior lights. All of sudden car is dead. car stops even the clock is off full electronic short. I have a 150A breaker in the back it did not pop but i manual reset it. Car now has electricity all accs work minus interior lights which the fuse has popped on again. Car now will not even try to start!! I turn the key and hear what sounds like a popping short noise and all electrics are dead again. I have to reset my breaker every time even though it is not popping. Now I pull the ground off the starter motor and I can turn on all accs. I even was able to put the 15amp fuse in and have interior lights. a new Fuse blew when trying to start it. I get a bump and start and drive it home. Car works fine at first then start to suffer from fuel pump problems. It starts bogging and lurching and almost dies at lights. I believe this is related to ground being pulled off the starter. (key ground messing with engine electronics). I’m going to take some pictures of a few of the problem areas I see. There is this unit I have no idea what its for but the box is cracked and theres dirt in it. Also a plug with a lot of cut wires. Is there anywhere i can take this where they won’t laugh at me for having such shitty wiring? The wiring is worse and worse the more electrical tape i take off. I have owned the car for over a year with out problems. I haven’t really done anything electrical to the car. Most recent thing i did was change a busted oil pressure gauge from electrical to mechanical. I have disconnect the stero and any wiring to the speakers/sub. Thanks for any help I’m really stumped with this one. ---

Yes lowered. So get this after cleaning a shit ton of contacts and checking for bad grounds everywhere with still no luck i ended up by passing my Hi-Amp buss. I believe this was installed for the stereo. I’m not great with car audio I’ve never cared to learn I really only use it when my gf is in the car (came with car has been untouched since purchase over a year and half ago). Either way I just randomly tried it and the car started up and idled perfectly. I even was able to put the 15amp fuse in with out it blowing. Now interior lights are working and car will start. ![http://img.photobucket.com/albums/v282/tamboman/parts%20for%20sale/grounds/DSC00125.jpg](http://img.photobucket.com/albums/v282/tamboman/parts%20for%20sale/grounds/DSC00125.jpg) Has anyone ever heard of these going bad? I’m about to go and pull it off the car maybe something melted through and it was grounding on the car chassis? I also am still interested in figuring out what this box is. ![http://img.photobucket.com/albums/v282/tamboman/parts%20for%20sale/grounds/DSC00123.jpg](http://img.photobucket.com/albums/v282/tamboman/parts%20for%20sale/grounds/DSC00123.jpg) Its on the passenger side tucked in the front fender. the case is cracked and its full of dirt. It must not have been the problem but still looks awful. ---

Darian wanted to mention about lowered cars rubbing through the fender harness. [http://www.sillbeer.com/fenderharness.php](http://www.sillbeer.com/fenderharness.php) I re-routed my harness on my old coupe once it was lowered… ---

I have mine zipped tied safely. I did check that though. I was driving around tonight and that fuse blew again. I’m thinking i must have a broken wire in one of my turn signals that hits the body when i turn or go over a bump something like that. It was working at idle fine. the pump seemed to run fine. I only was able to do a couple first gear pulls. Pulled strong until 5500-6000 then it seemed to plateau off. Change to second no problems. possible I still have a weak pump? Hopefully I can find this dangling wire thats causing my 15amp to blow tomorrow. Any good locations to start looking at?
