The fuse blowing is Fuse #6 20AMP.
I have trouble shoot by unplugging the connection to the pump and I tried another fuse and still blew. I have checked other fuses and crossed relay and still blew.

Customer: replied 1 month ago.
I removed the fuse PCM and tried another fuse in the rear and as soon as I put it in it burnt.
Expert:  Chad Farhat replied 1 month ago.

Hey good morning

you either have a short in the wiring between fuel pump & pcm

or the PCM is shorted out and needs replacement

Please let me know if you need anything else on it

Thank You
