It's most likely a bad "auto shutdown relay". Have you replaced it yet?
Rockauto has it for $4.82, https://www.rockauto.com/catalog/raframecatalog.php?carcode=1067172&parttype=16129
Here is the wiring diagram,
Did you order a relay?
remove the auto shut down relay and test the prongs in the socket and let me know if there is voltage there to one prong with the key off..
Ok, feel if that relay clicks when you turn the key to run.
Does the relay click?
I think it's either going to end up being the ecm, power to it , a ground or the wiring between it at that relay.
It appears to be the dark blue/white wire that feeds power to that relay.
Yeah, first I need to know if the relay is clicking. I assume it's not but just need to be sure.
If not check for voltage at both ends of that dark blue/white wire when the key is turned to run.
No, that is the ignition control module, the ecm (engine control module) is the computer.
the ecm might be right next to the battery.
The wires at the relay are dark blue/white not light blue/white.
Why don't you jump 12 volts to that dark green/black wire for now and drive the vehicle to where you are so you don't have to walk back and forth.
That is good, then you must have a bad dark green/black connection or wire.
Not for now, cause there appears to be a problem with the dark green/black wire. I know you jumped that wire at the coil and something worked, so disconnect that gray wire at the coil, the dark green/black wire at the auto shut down relay and using an ohmmeter see if that wire is open.
No, don't plug in the old asd relay.
Yes, you have to test for power to that dark green/black wire when the key is on run.
I don't think there is going to be.
I suspect you had no voltage at the fuel injectors too then. They are all spliced together, the coil, the fuel pump and the fuel injectors and they all get their voltage from that asd relay, so you see if either one or all of them don't get voltage then it won't start.
So, if you jump voltage to either one, check for voltage to the other 2 and whichever don't have voltage will tell you where the brake in that wire is.
Although technically speaking you should just test for voltage at that dark green/black wire at that asd relay when the key is on run and after you confirm there is voltage there, confirm at those other 3 spots, the coil, the fuel pump or listen if it runs and the fuel injectors, while the key is on run.
Did you give up for today?

Do you still need help on this or did you decide to close out this post?
What do you mean the green/black wire seems to be connected? Don't you have a voltmeter or at least a 12 volt test light? I thought you were already using a voltmeter or test light!
Tighten them bolts. If you don't have voltage at the dark green/black wire when testing, there is no sense in testing or worrying about grounds, unless you don't have a good ground on the voltmeter/test light. To make sure, ground the tester to the battery negative post, or if you choose to ground it to metal, test the ground by touching the positive battery post with the positive test lead to make sure, before you test anything else.
The fuel pump is most likely grounded back there near the fuel tank, so if you power up that dark green/black wire and the fuel pump still don't run, that would tell me that depending on what that fuel pump grounds to, either the frame or the body, I would say back near the battery, the negative battery post to the body and/or frame s where that problem is and most likely it will have an affect on other grounds. So, let me know if that fuel pump runs or not when that dark green/black wire does have voltage.
Figure it out yet?

How did you finally get power to the fuel pump?
After all this time, you are just going to leave me hangin?
