Usually longer than half an hour...
You said your check engine light was on for almost a year-did you ever have it checked out?

No I didn't have it checked out. The guy I bought it from said its always been on. And honestly the truck drove great. And alot of work was done to it. Do people that fix cars and trucks really come to this web page. I hope so. I need this truck to go to work.

You've got two threads going. I just suggested you check that the fuel pump is working and if not check the relay for it,

Thanks for your input. The fuel pump is working. I'm thinking maybe it's the distributor cap. I'm going to try that tomorrow. your cats adorable. I have 5 cats.

Part No. Price   Duralast / Control Module-Ignition
F121 $41.99
I don't know what you are capable of for testing. The relays are in a "relay block" under hood if info is right and some common problems are the fuel pump relay but you said you hear this, another is the ignition relay (brown on connector if like the cars) and very common is this module listed above for a no spark condition. This module takes a special socket to replace and can do with everything hooked up except the little bolts get rusty and make it hard at this age.
Relays will usually work once more if tapped with a plastic screwdriver handle. These are the common items for a no spark condition.
If you can test for spark that would really help. I'd like NOT to just throw parts at this without narrowing it down. I did see on this thread or the other that "Check Engine" light had been on for a long time but ran well. A code reading might help but I don't think that's it yet for this vintage.
You should be able to take a look at dist cap and rotor without tools. If it's not physically broken it should at least buck and poop for you so those aren't the likely problem with a no-start like you mentioned.
See if you can verify no spark or no fuel or perhaps neither. The inertia switch (check manual for where) has a reset but I doubt that's the problem - worth checking anyway.
Handy stuff to have: A 12v test light, starting fluid (spray) and a device to check for spark. With a bit of info we can pin it down better for you. Wild stab would be that module at this point if you wan't to toss parts,
