There was another recent thread that seemed similar but didnt want to hijack it. Ive got a 2000 limited 5.0 that all of a sudden wont start. I hadnt driven it in about 3 weeks but before that it ran fine without any issues, hesitation or problems starting. Its getting spark and I checked the fuel pump / PCM relays which were fine. I also jumped the in inertia shut off switch with no luck. I turn the key to on but dont hear the pump (although its hard to hear with the chiming when you turn the key on), and have cycled it on a bunch of time, still no pump sound. What are the symptoms of a fuel pump / regulator going bad? I was reading on another thread that the regulators on the 2000 limited are in the tank. Whats the best way to test it? Is it common for a fuel pump to just fail completely like this? Are there any other things I should check before dropping the tank? Thanks!
