SBF #5 30A Fuse Keeps Blowing
Ok so I have been following different posts on NASIOC but havent came to a conclusion. My SBF 5 fuse keeps blowing. From what I read it controls various things but one being the fuel pump.
STORY: First was normal driving and upon accel from a stop light car lost power. Long part short. It was my SBF 5 fuse that blew. I found this after removing and testing the fuel pump and the relay by glove box. Popped in a new fuse and car started and I managed to go to work (Kaneohe) and back. Made a quick stop at a gas station for a snackypoo. Started car up and it died immediatly. SBF 5 was again blown. Me thinking im awsome for buying back ups i popped a new one in and sure enough it blew again. Did another fuse being desperate and it blew. Well after my second tow home (first being the initial blow) (BTW Off Peak Towing literally lowered the flatbed into my garage and we let the car off and had to do no pushing to get her in there.) I am stuck in my garage now. I tried wiggling the wires and such to see if i can get the ground off and another fuse later I am typing this.
SO. I am looking to see if anyone has some advice on how to find the ground or can swing by to help. I have 2 fuses remaining and really cannot afford more ($5 a piece) and already blew 5.
Front and rear O2 sensors dont look damaged what so ever.

you still need a wiring diagram?

I had the same issie before. Check your maf sensor harness. Mine had rubbed between my intake and fmic and caused a short and blew the fuse non stop

Brown pin 6 on main relay (turbo model) goes to yellow/red (y/r) on pin 4 when relay is energized. Y/r pin 4 only goes to front and rear o2 sensors pin 2 (y/r) on both connectors. I have wiring manual for 02 model year & i doubt it would change for a 02-07 chassis. Suggest that you pull connectors off o2 sensors if you don't have a meter. You can call me @ 542-4024 if you have question.

Well if you ever get to a point where you're so frustrated you're willing to take advice from people, please don't listen to anyone that tells you to just put a fuse with a higher amp rating. LOL I don't see you doing it but I wanted to throw that out there. I've seen people take chances that aren't worth it during high frustration. Hate to see things get worse lol Glad you were able to work something out though.
