Still having wiring issues....Help PLEASE

The truck is the one in my signature...

Backstory;

I started the truck the other day and went to help a friend move...Well, we got all the stuff together, and I went to crank the truck over, and nothing...

Fuel pump primes, etc...

But now the speedometer won't come on, and the #17 circuit is dead...

Before the truck stopped cranking, the gauges all worked, etc...And I got power from the key switch to the fuse on #17....

Afterwards....nothing....


Any ideas? Because I REALLY don't wanna have to pull this harness, and swap it...Although, I've located one from a 1993 F-150 300/Auto......So I honestly don't know at this point..

GOnna go check the fuse link in just a second...

Just thought I'd throw this up for some help...

thanks all...

Side note-

All the lights, flashers, wipers, etc work...

And the reason I know that the #17 circuit doesn't work, is prior to the speedo stopping working....

It would get power from the ket switch to the Red/Green stripped wire's side of the #17 fuse....The red/yellow striped wire that powers the gauges....nothing....

Yeah, and they're all good...

Even checked the fuselink under the dash for the ignition....Since thats what gives the fuse panel power...nothing..it was good..

Yet, the #17 circuit (That the ignition wire actually hooks into) is still dead....Used to have juice on that side, and nothing from the red/yellow wire on up to the cluster...Now, its nothing period....

No blown fuse, but yet no power may equal a missing ground

I've only seen one ground wire so far...The dash, etc is STILL taken out...

Frankly, I just wanna get everything working again, so I can get my dash back together and have a usable truck


Any ideas on where anymore grounds are that would cause this issue...

You would still have power with a bad ground.

Have a bunch, but they are all in paper form, manuals...have you checked out any neutral safety, or depressed clutch pedal type switch, that you may have kicked a wire loose...you could buy a Haynes, or your local library may have one to lend ya.

I have a Chiltons'...

And I had to jumper the NSS over, because it went bad....Could it have messed up, further? Just a thought...

This was totally random...It all started with me chasing down no power to #17 circuit...

Friend of mine needed help moving, I started the truck and went...No issues whatsoever...

When we got ready to leave, I turned the key over, and NOTHING...The fuel pump primed(s) and when you crank it to the start position...Nothing...

I've been having to turn the key ON, and use a screwdriver to jumper the fender relay to get it to start...
