P0230 Fuel Pump Primary Circuit Malfunction (wha? blown fuse?)
one more question, do i really need to take out the fuel pump fuse every time i flash the pcm? anything bad happen if i dont, just curious.
who programed the x-cal for you?
as in the fuel pump i never take my fuse out
that part of the instuctions is so you wont run you battery out during the down load and get screwed with only part of the program installed
the info i got is some veihicles take very large programs and upload times so they put that in the instuctions for all
our Rangers only take a couple of mins to up load and you not running all sorts of stuff,blasting the sterio or the air,you will be ok
