Check the throttle position sensor with a ohms and volts meter.
I dont know the process but others in the forum might.
There is also, on the front page of the forum a bunch of sticky notes. It is possible that the diagnostic process might be in one of those.
Welcome to the forum.

Welcome.

Have you tried your spare pmd?
replace the 1/4” fuel return line with clear tubing and have someone cranking while you watch the fuel flow for debris or bubbles.

Please space out your typing a little bit, it makes reading it easier for everyone on phones- which is most folks.
If you put the vehicle description in your signature, each time you post it shows up automatically to help folks reading along in diagnostic. Marty’s is a good example, mine is mild because few alterations were done.

I had to go scroll up and check. I dont see the sig. line in My posts some more now. Seems I used to be able to see it.
Guess the forum software might have changed so that the owner of a post dont see their own sig. linesz

turn your phone sideways Marty

turn your phone sideways Marty

Your phone sideways, not your head, @MrMarty51!

 

[jrsavoie]

I turned my phone sideways. Turned my head sideways. Went out and got all sideways.
Still don't see no stinking sigs

 

[ak diesel driver]

Maybe your phone is not compatible

 

[Husker6.5]

Quite possible. First photo is sideways (Landscape) second vertical (Portrait). Landscape shows site stats and signature, Portrait doesn't. My phone is an Android OS Samsung Galaxy A32 5G.

It all depends on the browser and how up to date your phony is. there are a lot of so called newer phones out there that use yesterdays updates. I have found on several android phones they use random default pre-installed browsers. it all depends on the manufacture and the service provider they came from. example is Samsung phones and tablets that are from att they package the operating system with their apps and bloat ware that seems very annoying to lots of folks.. usually if I have an android tablet or phone, the first thing I do is root it or jailbreak it as they call it and ether remove all the crap and install what I want, or search for a custom operating system that was built from the base stock android os and not touched by any of these companies.

Apple I use for my daily driver on my phone. I switched years ago due to the mass advertisements that would pop up in the android notifications. Apple has a good handle on that side of things.

I didn't even know that was a possibility.
I don't even know at what point in time I quit being able to see sigs

Did you LOAD test (not voltage) test the batteries one at a time?
