ALRIGHTY. The parts suburban wars continued today. KEEP IN MIND, THIS IS A PARTS TRUCK. The rust is far too much. For brief history: i bought this rig a year ago now, been sitting for like 10 years prior to that. Very complete, but very rusted. Especially the frame. Never ran, never really tried. Being it reeked of turpentine and had a hole in the fuel tank, figured i'd get a new tank, sending unit and fuel pump (TBI) instead of putting it in the system. I did this last winter and tried to start it and the fuel pump never worked. So i replaced the firewall relay hoping it was the easy way out. Relay now works but still now power. It was cold, so i put it off for a bit. Keep in mind i've already pillaged this rig in numerous ways for the Jimmy project, including things like important ground straps. So i had installed 3 recently and now my power windows work and i was able to get my rear power window up. This was terrible because the latches were seized and i had to screw with the little electrical box it has to make contact with to show it's shut to work (i think that's how that works, i'm not a power window guy) SO that was a huge win getting that all sealed up normal. Then i pulled out the sending unit and checked the fuel pump and connections. Connections were great, new fuel still was great, etc. Tested the fuel pump on a battery on my bench and it worked. Put it back in the tank and ran it on a battery and it worked, but didn't push any fuel? Plugged the truck back into the sending unit plug and turned the key and it didn't turn on. Now i had checked this with a test light and it worked, but i only checked one. Stupid me was under the impression one wire in the plug was power and the other ground. I know, i'm an idiot. One is fuel level, and the other is for the fuel pump. The ground is completely separate on the unit. So i jumped the tan and white wire from the relay to the plug and it activates the fuel pump, but i don't feel like its running as long as it should. My dad's TBI '87 dump truck fuel pump relay runs a bit. Put more fuel in it and cranked and cranked to no avail. Perhaps the other wire needs replaced too. Chances are if one is bad in the harness then others are too. Other being the orange one from relay to plug. Perhaps i'll change on that one tomorrow and see if that works.
