i was driving my 02 jeep grand cherokee home and it kept running hot so i pulled the thermostat just for it to keep running hot and about 5 minutes from home it ran hot and stalled without warning and when i went to start back up after cooling it down my guages would not work along with my headlight not working but there was power to the cluster. my skim lights is on now and i have replaced the cam and crank shaft sensors and wiring to the connectors and the only codes it has gave me is the transmission fluid pressure code?! the jeep will only turn over but will not fire there’s no power to the fuel pump and all the fuses and relays are brand new… someone out there has have to dealt with this !???

I guess the question is , why is there no power to the fuel pump . Need to trace that back .
don't forget that just because something is new doesnt mean it works.
my first thought is swap the asd relay I'd it has one for another. Takes two minutes.
Maybe the fuel pump has died ? Could have been running hot because it was leaned out ?

There is power to the fuel pump but because of the guages not working it’s not sending the signal back from the pcm to the pump so “technically “ it doesn’t have power . and yes i have double checked the add relay and no pump is still working as should it’s reading a good number for fuel pressure and the cam and crank sensor have been working since i’ve replaced them but like i also said my immobilizer light has been on since it stalled also so i’m scratching my head on this one
