i have a 2014 hyundai accent 1..6. The fuse panel under the hood keeps blowing my injection fuse 15 amp d the one beside it sensor 10 amp. First it just died put fuses in and drove around for about and hour then when it popped them again. So i installed new fuses again and the minute i had went to crank it over it popped the 2 of them instantly and did so repeatedly about 10 times in a row .......So i cancelled some things out on the wiring and it led to the fuel tank pressure sensor disconnected it from the wiring and the fuses stopped popping. so left it disconnected over night and wife went with the car the next day with the sensor still disconnected and it popped the fuses again after a little driving. Sp brought it back to the garage reinstalled fuses car fired right up only now if i put it in reverse and hammer the thrttle down it will pop those 2 fuses again. consistently when it goes into reverse now. But yesterday i could even turn the engine over completely and they popped. This is really throwing me for a loop. i have the full wiring schematic.....and neither of the 2 circuits are joined anywhere according to the schematic but yet they both pop together.....under the fuse panel is like new connections are all beautiful......could really use some input..........thank in advance for any help.........

 

It sounds like the wiring loom is busted and the two wires are frayed
Exposing the wiring. Vibration and they short out and blow the fuses
Good luck finding the short.

 

Same problem here. do you have any updates ?

 

Unfortunately, sometimes a person will post a problem but won't come back to post the solution.
So, we don't know if we helped to find the issue or if they found it on their own.
Either way ... no help here

 

I just joined to help others solve this.
Under the master cylinder there is a trans bracket the wiring harness is attached to and rubbed thru on the edge of the bracket,. It was only popping the 15 amp fuse but more then 1 wire had wear marks.
Hope this helps others
