I have a nice Dakota with 318 v8 only have 8.3 volts at harness for the fuel pump any ideas

 

Have you confirmed you have 12 volts at the battery? Trace it back and find out where its losing voltage. Probably a bad ground somewhere.

 

IDK about the voltage but I di have this link to a page of TSB's for the 96. It might help you. http://dodgeram.info/tsb/group_14.htm

 

I just had to drop my tank today and pull my fuel pump from my 90. Must be a bug going around

 

I've got 12 at battery I have same truck same year for parts only single cab I'm driving cab n half so I switched harnesses rite at fire wall n still only 8.3 at pump plug
I'm not good with electrical issues

 

Checked out that site link there didn't find nothing on there

 

Check at the ASD; if it's failing, it might have excessive resistance.

Then check the wiring resistance between the ASD and the fuel pump.

Where are you measuring the 8.3V at?

And *broken record mode* Do you have the factory service manual for your truck? The Chrysler FSM? It's a lot easier to troubleshoot with proper wiring diagrams, and the Chrysler FSM will have a troubleshooting tree for you to use.

Like the manufacturer manual

 

What do u mean by asd Ralph
And I'm getting the 8.3 v rite at plug clip that goes to fuel pump

 

The manufacturer's manual, yes.

ASD - Auto Shut Down relay. It turns the pump off when the motor isn't running.

And which pins are you measuring at? You MIGHT be measuring the fuel float at 8.3V ...

But even more, if you're not bypassing the ASD, you may not get voltage to the pump when it's not running (since the ASD interrupts power to the pump and the coil(s) when the motor isn't running, hence the Auto Shut Down part.)
