I used to mainly do a visual on such as that.
Look at pushrod ends, are they beginning to appear sort of going to a point shape ? ? ? ?
Rocker shafts on the bottom/pressure side, how much wear and is there any galling going on ? ? ? ?
Driver too is USA made.
I am surprised that they are since Flight Systems was bought up by Dorman and their drivers is made in commiepinkochina.
Let us hope they dont change that.
IDK about other parts stores, the Dorman drivers through Oriellys too is lifetime warranted. IDK if one purchased...
Welcome to the forum USPro.
Most likely a fusable link, or, if there is a underhood fuse box, one of those 30 amp main fuses is blowed out.
Open the hood.
Above the left(drivers side) fender well there is a black box.
Lift the cover by releasing the two latches.
Lift iff the cover, flip over the...
It seemed to me from my past years in the square body trucks I had that it could be the possibility of two fuses.
I could remember that there is a gauge lamp fuse but I could not remember which fuse the other one was.
Yup, tail lamp fuse.
Didjuh check the fuse ? ? ? ?
IIRC, there may be two fuses to the dadh light circuitry, somehow if on or the other of those burns out or looses connection then there will be no dashing lights.

I had one on my truck and it was running and performing great.
About 100 miles it began to leak.
One of the extension nozzles...
Engine in my truck has a terrible noise. Almost like the injectors but after it warms sort of goes away.
With the limited abilities of my ears, it sounds like from the RH side.
I did make an attempt at doing a retorque on the exhaust manifolds after the new engine was in and runn ing but is...
welcome aboard Cliff.
I’m thinking maybe @dbrannon79 has pretty much nailed it.
Block wheels so it can not roll.
Crawl under and look at position of shift arm on the transmixer.
Insert key in ignition and turn to run position, press hard on brake pedal, turn key to off, if it will, back under...
Oh yeah, also, I have the top side harness connectors and the bumper ends all three numbered, if one fails then I know which one it is and can then remove it without guessing.
Also, I have not had to replace a pump driver for l quite some time.
I no longer call them a PMD or pump mounted driver...
That sounds to me like the typical PMD failure.
On My truck I have three PMDs mounted on heat sinks with remote harnesses strung to each one.
One driver is a Dorman that I am currently running on and Oriellys life time warranties those, dont know if other parts stores does or dont.
The other...
Throw a new PMD at it and see what it does.
As @jrsavoie suggested, be sure it has a new resistor installed within the PMD plug too.
I was typing same time he was posting. 😹😹😹
I had the sending unit screwed into the fitting right at the IP.
Before I knew about the snubbers I was replacing sending units right regular.
I’d have to lift the upper intake to get enough swing on the wrench so after I got the snubbers I did the remote hose system but used 5/16ths 30R9 hose...
