    In the first chapter "Stumped" I was reaching out for any advice. I received plenty and to all who of you who cared enough to provide your feedback, I say THANK YOU!! Now in chapter 2 here's the results of my findings. New battery less than a month old, cables clean and good connection, crankshaft sensor replaced, fuel pressure regulator replaced, fuel dampener replaced. These 3 parts I'm confident were not the issue but they were not that expensive and fairly easy to replace. I removed timing covers and inspected belt, all looks good. I did not replace camshaft sensor. I'm rolling the dice on it being good. Checked fuel filter, all good. I had replaced it a couple years ago just because it had never been changed. Performed spark test with a noid lite on all eight injectors and getting spark. Checked all fuses that were suggested and fuses are good.
    Here's a bit of advice only from my personal experience, watching youtube videos on just about anything out there is fine, I do it all the time. However this is one time I wished I had picked up the service repair manual I bought 20 years ago that I keep in my desk and know right where it is, and READ IT FIRST!!! There were some things in there that I never considered and the videos never touched on either. Like for example making sure to depressurize the system before jumping in on any fuel related work. Yeah messing with anything under pressure can be dangerous especially volatile fuels!! If you have the repair manual for your vehicle do yourself a favor and use it for what it's meant to be for.
    I'm guilty of wanting to watch someone on a video do something and explain along the way what there doing rather than sitting down reading about it. I think most of us are that way. The manual is the way to go first. Then watch the videos. Just my 2 cents. Now to the big reveal. After all that was done I finally put a pressure gauge on it and guess what? Not a single pound of pressure, even though when I was first trying to narrow this down I could hear the fuel pump when turning it on so I put that on the back burner.
    So from what I've described does anyone think that the fuel pump is my culprit? I'm fixing to dive in head first and tackle it. If it turns out to not be then oh well, it's 24 years old bound to go sometime. Just something I can mark off the future list. Anyway I'll keep ya posted on how I'm doing. Thanks to everyone again for all your input I truly appreciate it.

    Pretty sure Chapter 3 is more appropriate....

    As someone mentioned in either your 1st thread or 2nd, when turning key to IGN ON, one can not hear fuel pump because "fuel pump won't engage until the crank sensor sees the engine rotating".
    Taking into account all you've mentioned in 3 threads, determining if the fuel pump or it's electrical circuit is functioning properly is not a bad idea.

    Do us all a favor and at least link to your other posts. Better yet, contain all of them in one thread. So annoying...

    Keep researching. And when researching, pay close attention to advice given and information you are presented with. In this case as @BubbaW mentioned, someone already told you that revelation you just shared with us. You need someone to crank the truck while you monitor the fuel pressure gauge. Fuel pump will be active when cranking and when engine is running. Otherwise it will not be active and you won’t have fuel pressure. Also agree with @ATBAV8 , stop creating new threads about the exact same problem. Now no one knows what you’ve been told already or what you’ve already tried.

    Show us the wire routing on your crankshaft sensor.

    If you used an aftermarket fuel pump, yeah, I believe it, we've seen it plenty here. Aftermarket rarely lasts more than 2-4 years, unless it's a quality brand like Walbro. Parts store brands are a joke nowadays.

    But heed the advice above. I don't understand how you "hear the pump turning on", that's not something that happens in these trucks until the key is kicked to the ON position. As you'll see in the FSM, I believe, which you have in a drawer.
