right at the back of the tbi for the high pressure line I have a threaded hookup for my gauge and it ran 10 psi on and a ~14 psi primeCurious - what do you call “good”? And where did you check it?

Kinda strange--I'd expect the same pressure "prime" as running. What is the fuel pressure at heavy load, or with the bleed button pressed so that fuel drains out of the pressure gauge assembly?right at the back of the tbi for the high pressure line I have a threaded hookup for my gauge and it ran 10 psi on and a ~14 psi prime
Pump is a year old, did that and rear shocks at the same time with the bed off, fuel filter is less than 3mo old. Always fuel at the same chain of stations bc lots of the gas stations around me are notorious for having water in the ground tanks. As far as under load i didn't test for that, the prime psi may have been my 15 dollar gauge spiking bc i cycled the key or organic operator error as im doing this by myself and being in the cab and under the hood simultaneously isn't really a possibility for me lol.Kinda strange--I'd expect the same pressure "prime" as running.

How old is the fuel pump and filter?
They say 10psi is within spec. That said, I had a cold start idle problem once with pump ~a year old from Autozone. I couldn’t figure it out and checked fuel pressure. It was 10psi but I noticed it dropped a bit when I blipped throttle. Assumed it was ok and chased my tail trying to fix the problem until I eventually got TunerPro and found that an idle enrichment flag was kicking in/off running my idle up/down. Replaced the pump with AcDelco or Delphi, can’t remember, and fuel pressure was a solid 13psi even when blipping throttle. Problem went away.right at the back of the tbi for the high pressure line I have a threaded hookup for my gauge and it ran 10 psi on and a ~14 psi prime

Perhaps I should have explained more.it needs to remain solid with increased demand which is why I assume Shurkey is suggesting watching fuel pressure with bleed open(not something I’m familiar with myself).
Hey all, new day. New issues. Now it's sounding like I'm missing 4/6 cyl on top of my old issues (see attached link) it's really the full package. Spits sputters backfires through exhaust extremely rich to the point fuel is all you can smell in the cab. And more recently stalling. Unplugged Map and it ran "better" still rich and hacking a lung but doesnt stall. Although I may have to attribute that to it being 32yrs old and at 2000ft above sea level trying to run on predetermined map layout. No new codes, still have yet to get my obd1 scanner in the mail. And to wrap it all up I have to get to paducah ky from my area of ND (1400 miles) by the 9th of next month. Can the duck be saved or am I selling it to buy a prius. Sorry to rant I'll be on all night to discussHeyo, 91 k1500 4.3 4x4. I have a maybe 10-15s crank time then she'll kick off and either high idle for 30 seconds then die (no tach so I would guess about 13-1500 rpm) or it will just right off die. Tried to pull codes off the CEL but just get the system active flashing and I do not have a obd1 reader. New parts include Coolant temp (both) ICM, MAP, Plugs, wires, cap and button as well as new vac lines all over bc rot. Motor was re-sealed and had a timing job less than 8k ago. WTF
