What was the fuel pressure?

The fuel pressure gauge was not reading anything at the fuel rail. I had all the proper fittings connected and all that. It wasn't picking up anything. So, I guess the Schrader valve on the rail is either worn out or just stuck. The fuel pressure gauge was brand new. I rented it from a local parts store. So, to answer your question, I have no idea what the fuel pressure was.

Got it.
Knowing the pressure sure would have helped you.
You should be able to get a new shredder valve from the parts store. This way you are not just replacing the fuel pump without being sure. Also, if you have not yet changed the fuel filter.
Also, a clogged fuel filter can reduce the fuel pressure. Has that been replaced?

I found the problem. There are three faulty fuel injectors. I have a set ordered. I'll let you know how it does after I change fuel injectors.

Glad you found the problem. Were those injectors not spraying properly? Clogged?

The injectors were mechanically stuck open. Constantly spraying gas.

Sure is. I have a set of 8 ordered. They're supposed to be here Tuesday. If the weather permits, I will change them Tuesday if it's not too late. If it is then I'll just do it the next day. Thanks for all your help and advice on this subject.

Good morning. I received the new fuel injectors. Then I had to have emergency surgery or lose my foot. Well. While I was in the hospital, my stepson said he knows someone who can change the injectors. I said okay that's great. Well, when I got home from the hospital yesterday, I popped the hood on the truck to check things out. I was very seriously shocked to say the least. Almost the entire driver side of the engine was burnt! Now this guy isn't answering my stepson's calls or anything. My question is, what would be a good, educated guess of repairs needed now? I know these for sure: coil packs, fuel injectors, hoses, EVAP solenoid, mass air flow. When I am able, I will take a few pictures to send you so you can see the damage done. And can I force him to pay for the repairs.

Wow, that is crazy with the truck. I wonder what he did.
I hope you are doing well though.
As for the burnt parts, can you upload a video of what you can see is burnt?

That is quite something with all the damages. I think it will be the best option, as you mentioned in the video, is to go to a junk yard and take off all those components from a truck. All the harnesses and lines and any other burnt components.
From the video it looks like all those plastic components got burnt.
Did he install the injectors on this side?

I would need to remove all damaged components. Would I remove the main power cable from the PCM to the battery?

If the main cable is burnt/melted, then yes.
From the video it looks like good amount of work. I think the best approach would be to first get those replacement components then start the remove them from your truck one at a time. This can help with keeping track of all the locations for those parts, especially the wiring harness.
Can you tell if it melted back of the injectors?
