All you did was unplug the old pump then plugged in the new pump into the YJ fuel pump harness, right?
the first answer is/was, that was kind of the million dollar question,
but going by your if/then statement, if no then's are possible, it makes me presume that the if is not actually a true statement.
the second answer is yes- well no, i mean, of course i checked the fuel filter and all that, after switching the pump, I think we went down the whole line to make sure everything was good. honestly i think we started down the line, but didn't make it all the way down and so the test not performed for a bit later.
fuel pump #1 ate itself.
again, we went out, came back,
*i think the battery was dead the next day or something, i can't exactly remember,
either way when the battery got power, the fuel pump came on,
the whirring noise cause to an audible decibel, and then turned into a horrible grinding and stopped.
then the jeep wouldn't start. I opened the tank, i think we chased some wires,
this was october of 2009. My memory is kind of vague on it,
I was on Boot leave, so this was all in a ten day trek,
and due to the occurances before and after,
those ten days are a little vague.
Okay, Okay, - so here it goes,
after all there pages we have gone through,
I am going to try this to the best of my ability....
If I can please,
direct your attention to the picture of the green connector.
read this first then look at it,
and you might be able to see the details i explain....
There is a pinhole in that connector,
and out of that pinhole comes TWO green wires,
one has a yellow stripe,
and one has a double light green stripe.
if you follow the yellow striped one,
you will see it has a large blue splice attachment clip on it,
with a third green wire stemming off of it,
also with a yellow stripe.
the original yellow striped wire goes straight to the ecu,
and even with the ECU removed, it is hot.
the spliced yellow striped one goes to the fuel pump,
and even with the fuel pump removed, it is hot.
which leads me to believe that the green wire, with two light green stripes,
it my source of hot.
so someone please confirm whether this sounds like a likely scenario, or impossible-
one day, I'm driving in the mud,
me and my friends enjoy ourselves for hours,
and the day ends,
and i wash the jeep the next day.
*during this time*
there is a wire,
or a relay,
or a component,
and it either gets- melted, wet, seized, gremlin spliced- etc-
to that green wire with the double stripe.
changing that wire from a sometimes hot,
to an always hot.
which fries the fuel pump,
once making it grind,
and once maybe shorting it on the inside?
and of course, draining the life and soul out of the battery.
-on a side note, i have both fuel pumps sitting here, ready for interogation...
-and due to this possible scenario, until it is decided not possible,
I'm going to try to find some of those always hot lines and see which one is shooting into that green wire, digging around the ignition and that 60 pin connector and such.
