05 JEEP TECH QUESTION
I think I might try a temporary jumper wire(s) to the fuel pump if possible. I found on a van that seemed to be killing in tank fuel pumps, the lead actually corroded inside the length of the jacket. Once replaced, it was fine.
FWIW, on that crank sensor, if you do change it, sometimes they are a pain to remove. Some try to force them out and end up breaking them off. Scrape any paint or rust build up that can cause a bind on you. Use a penetrant to help "work" it out. Alot of people say to use the Mopar branded sensor for replacement. I used the NAPA (Echlin) with no issue.
Turns out, I learned from youtube, it was the ignition switch.
Lol, a few years back, my '05 Ram could have the radio playing hours later after shutting down, as if the key was on "accessory". Unlock and open the door the "key in ignition" chimes start playing. If I smacked the dash bottom I could get the radio to stop playing and chime quit. Since I replaced the switch, it's been fine.
