Fuel Pump Wire ?s

[Mattman6]

Hello I just got my first 89 Comanche. Well I am already having a few issues with the fuel system. I believe it's trash in the tank or something to do with the fuel pump. The PO told me he was changing the fuel filter reguarly, so I changed it the other day. However I am still having some problems when the truck is running sometimes. I plan to drop and clean out the fuel tank this week. I also may just replace the fuel pump as well. 

 

My question though is the Fuel Pump wires. As you can see from the pictures there are some wires that are not plugged into anything. I was wondering if anyone could help me identify what exactly is going on with the wiring job someone did in the past. 1989 4.0 I6 4wd Longbed.

I'm hoping to drop the tank today. So any input would be great

Here's the '88 electrical manual, wiring should be similar. http://comancheclub.com/topic/12083-electrical-manual/?fromsearch=1 and here's a pic from the '89 FSM. MJs are 60 series.

Thank you! Got the tank off today and will post pics over in my build thread.

That's a butcher job. Looks like he wanted to add a supplemental ground.

 

You're on your own. I doubt anyone can figure that out from pictures.

That's what I figured. I am going to try and work through it. The fuel pump works I'm just getting some hesitation 20% of the time. I have a feeling that the crud in the gas tank is causing a lot of issues.
