So, I made the mistake of bragging about how good my cars been since I've had. I've had it two years and have only had to do brakes, tires, oil and a tune up. Now it's making me regret it. So my problem is that my u/h ign 15amp fuse keeps blowing. I don't have access to all data to be able to do some circuit testing. Codes include (not all are related)(all P codes) 0443, 0102, 0121,0122, 0123, 0135, 0243, 0463, 1121, and, 1122. I don't believe it's a faulty component as if I disconnect them it still blows the fuse at some point. The only thing I've done so far, other than unplugging things is to check the wires and I've found that the pink wire (think it should be 12v, not 100%), doesn't have 12 volts and has continuity to ground. I've tried wiggling wires to see if I can break the continuity but no luck as of yet. Without a wiring diagram I don't know what all components are on the circuit, so I don't know what all needs to be checked. This is pretty much what I need help with. The gas gauge is also very unsteady, empty is empty, but 1 gallon makes it full and 5 gallons only gives half a tank. And the tps sensor sporadically hits 100%, even after It's been replaced with an OEM sensor. Not sure if it shares a ground or power from the maf sensor. But it seems like these are all wire related, not bad components. Sorry for the lengthy post, trying to give as much info as possible. Thank you in advance.
