bronco quit running

Hey,
So I'm a mechanical noobie. Have a 88 bronco with 110k miles.
Yesterday I started my truck to warm it up, started right up. After about 10 min it died. tried to start it, it just continually revs. Thought maybe it was out of gas, Put more in, but had no progress. Not sure where to go from here. Had read possible fuel pump issues. Had been idling rough recently as well. Any info would help.

Thanks

Honestly like I said I'm pretty un informed myself. It's done a few different things. Was turning trying to fire, but now when I turn the key it turns a few times and clicks.

Sounds like now the battery is to low. Charge it up and let us know
from there. If batt is charged and still does the click thing than clean
ALL connections in the start circuit. IDK

So the batt is hot now and it still wont crank over and just clicks?
Or now with a hot batt it will crank over but not fire? It's hard to
see what you see through the computer Bud. Just trying to get
a picture in my head of what is going on.

Yeah I understand. Lol just not mechanical enough to really answer properly. Before when the battery was hot it turned bunch, sounded like it was trying to start. But never would. Will be charging the battery more later

Essentially the engine doesn't seem to be getting fuel. Wondering where to start. Fuel pump?

Well first, run the codes and see if anything pops up. You can do it with a code reader that you can buy for $20 to $30 at an auto parts store, or on amazon. Or you can do it with a paper clip. (Ive never done the paperclip method before, but others on here have) Check your fuel pressure if you can. Let it idle and watch the gauge, especially while its reving (if it does) For a 351 the pressure should be just above 30psi I believe. Im not sure for a 5.0 but it should be around the same. If the fuel pressure is low, or if you feel like digging around, check the fuel pressure regulator, which looks like a vacuum canister on the top back towards the driver side firewall. It should be held on by three allon head screws that are a pain to get to. Also you might want to check the voltage getting to the high pressure pump. Thats about all I can think of for the fuel system. Make sure to check your codes to see if any sensors are out of whack.

Let's check if the fuel pump is stuck: with a hammer give some taps to the fuel tank and try to start the engine.

Check/ change your fuel filter. at 110K it is probably full of crap, I have had them clog to the point they stave the engine.
