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.- Grit dog

Intake plenum gaskets
So it runs good enough to pull a horse trailer down the highway? Seems only problem then is the priming issue?- Grit dog

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!- Grit dog

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...- Grit dog

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.- Grit dog

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...- Grit dog

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.)...- Grit dog

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
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...- Grit dog

Show me your 8 lug wheels!
Seems odd that H2 wheels with relatively skinny tires would rub at all.- Grit dog

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...- Grit dog

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...
