I know this is my first post on here. I have been a long time reader. I'm active on a canadian 240sx forum but I really need some help from some experience 240 owners.
Heres the story. Thanks to anyone in advance I really appreciate it.
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.
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 stereo and any wiring to the speakers/sub.
Thanks for any help I'm really stumped with this one.
