    Do I need an electric fuel pump!

    Doesn’t need an electric fuel pump. But not normal for sitting a few days or weeks or months. Needs a little carb work sounds like.

    Intake plenum gaskets

    So it runs good enough to pull a horse trailer down the highway? Seems only problem then is the priming issue?

    12v ignition switch source

    Yup on all accounts. My truck will start and run for about 30sec with the hidden switch off. Then it dies. Suddenly It aint got no gas in it!

    12v ignition switch source

    Yes when the engine is running. No when the key is on but engine not running. The relay I mentioned you don’t need. Your car already has that safety feature if you will. But for vehicles that don’t have efi supporting electronics… It primes the system for a couple seconds when the key is...

    Stock rim width

    If they’re GM 8 lug aluminum 8x6.5 then they are most likely the PYO wheels. Since you didn’t specify width. Those are 6.5 wide. 285-75s work but are balloons. 285-65s are pushing it imo.

    12v ignition switch source

    Mine (86 with a newer engine and electric fuel pump) was run from the electric choke wire…eek when I bought it.) I kept the choke wire as the trigger for a relay. However you don’t want just a simple relay (long term anyway) as that will put power to the fuel pump 100% of the time when the key...

    Intake plenum gaskets

    Ok separate the issues. 1. Pumping the throttle 80x to start is 90% likely carburetor related. Accelerator pump worn out. It’s the little plunger thingy under the top lever. Not difficult. (I am also NOT an expert on Q jet carbs so anyone feel free to correct me. Just trying to be helpful.)...

    1987 GMC High Serria K20

    Nope, all but certain they only reproduce the Sierra Classic 2500 emblems. I looked long and hard for High Sierra 80s 3/4 ton badges. No luck

    Intake plenum gaskets

    Sounds like @Catbox kid could have a side job here. Pretty sure Maxwellvis knows more about Chebbie motors than this persons parts replacer. Seriously. @yellowdog5 if youre anywhere within range of Portland this guys kid can fix your minor issues.

    Intake plenum gaskets

    In keeping with the original question while you get help diagnosing the actual issue(s) which sound 90% carb related, it does not sound like your intake manifold gasket(s) are the problem. If it was leaking oil out the front or back, eating coolant or had a vacuum leak (this one is still...

    Show me your 8 lug wheels!

    Seems odd that H2 wheels with relatively skinny tires would rub at all.

    Engine cranks, but only starts after letting off key? - I'm perplexed

    Did they put a whole new distributor in it or just a cap n rotor or? Sometimes it’s the oddest thing. That’s why electrical gremlins are called gremlins. For instance son’s mustang was throwing cam sensor codes and running poorly. New cam sensors didn’t fix it. It was alternator diodes causing...

    What have you done to your square lately??

    Not sure if you were replying to me as I posted, maybe in this thread, about needing a window motor. On the 77 Is this the case on the 70s window motors? Reason I asked is the PO (I just bought the truck) was surprised the drivers window didn’t work. Said it always worked (for the few years he’s...

    Engine cranks, but only starts after letting off key? - I'm perplexed

    Even though you have a “modern” squarebody, lol, it’s still going to me more subject to experienced diagnosis rather than most shops/mechanics now who are frequently only having to do computer diagnostics and replace parts. Idk how old school your shop is, but finding someone who is experienced...

    Engine cranks, but only starts after letting off key? - I'm perplexed

    Now leaning towards maybe something heat soak related under the hood. IGN module or even coil. Coil windings expand as they heat up. Could need just slightly more power when warm/hot to do coil things and it gets that power as the draw is released from the starter motor. Don’t recall, if you...

    Color blind! Burgundy or Maroon?

    ^What he said. And idk how or where you’d get custom color vinyl dye. Just get can each of the 2 closest colors you can pick and go from there.

    Color blind! Burgundy or Maroon?

    IMO maroon and burgundy are bout the same color. And the trim paint colors will be more about what matches, is close or what you like. Blending a couple colors or shades can also dial it in sometimes. Example, this is the color of my interior. Light buckskin. The paint is used on the new pieces...

    Ice Cube Fuse Fail

    Yes. That appears what happened. No need for the others to argue about it.

    Engine cranks, but only starts after letting off key? - I'm perplexed

    I was thinking heat soak possibility as well, but that doesn’t make sense with the ignition switch since it’s in the cab and doesn’t see heat from the engine. Guessing they didn’t actually hot test it at the shop, if you immediately have the same repeatable condition. I would have bet dead...

    What have you done to your square lately??

    Amazon delivered new twice pipes in 2 days. Got home late but got one mocked up real quick. They’ll tuck up a smidge tighter. Close as I could get it with c clamps. Once they’re mounted, hooking them up will be super simple Looks pretty rad!

    Proper process for painting most of your interior parts

    I don’t follow directions well, lol so haven’t read the write up. But have had good luck with SEM color coat and I just prep it with a quick wipe down of paint reducer. It’s a hot enough solvent that it softens the plastic or paint a bit. I feel that helps the bond.

    Proper process for painting most of your interior parts

    I got about 3 years on the velour door card inserts and the bottom of door carpet piece. Used SEM. Still looks great. Granted the truck doesn’t get a ton of UV exposure. It’s parked outdoors maybe 2-3 months total per year. Mostly summer and sunny though.
