This blue plastic conector pluges in on top of the fuel pump and has a loop at the other end that is raped around the wireing harness as if just to keep from losing it if it were to come out of its conection point. If I had my buddy hold this conection tight then the fuel pump will run and the truck will start. This has to be held into place to run though I do not know what the function of this conection is or how to fix this problem and can I just pick up a new one of these conections at the parts store?

I own a shop, and what you are talking about is the connector plugs on, and it is held in place by this lock that plugs into the connector. If the plug is broken, the lock doesn't work, so what you will have to do is; either go to a junkyard or the dealer and purchase a new connector. DO NOT just twist the wires together as they will get hot an burn the pump out. Solder the connections, and use some heat shrink to seal the connections, or use some stuff called liquid tape you can purchase at Wal-Mart in the automotive section. If the part is broken on the tank side of the connector, you will have to replace the fuel pump, and/or the float assembly unit in order to get the connector to stay on. Either way you have a problem, and until you fix the connector properly, it won't stay connected.
Glad to help out, Good Luck!!!

I believe the blue plastic thing you are talking about is only there to hold the connector in place in case the locking tab breaks off. That the truck only runs when it is held would make me think you have a worn, loose or dirty connector or a broken wire in the connector. First thing I would try is replacing the connector with a new one. Should be able to buy a new pigtail fairly cheaply. If that doesn't help, you may have to replace the unit in the tank. They occasionally have trouble with an internal connection overheating.

You know where the problem is, now you have to find out which part is causing the problem. Is it the fuel pump or the connector? Take it apart and inspect it. It could be nothing more than corroded contacts. Try using a pencil eraser to clean the contacts if you can, then reinstall the connector and see if it works. You could always find another at a salvage yard and cut it out and put it on your truck using butt splices and heat shrink tubing to keep it water tight. good luck.

Obviously the connector is broken. They usually have two small clips on the side to hold them in place, if they are broken or loose they will not hold the connector tightly in place. Thats why when you hold it in place it works. If you are not experienced in these type of repairs I would suggest that you take it to a mechanic and explain what is happening, it should be an easy and fairly cheap fix.

You can try replacing the terminals in the plug, but i suspect it's in the sender. Try the terminals first, that's cheap, but if it's in the sender, The only way to fix this problem, remove the fuel sender from the tank and replace the sender,

Could be a power supply or a control wire. Autozone.com has this cool online parts book. Or just get a book thats on that make model and year. it will have fuel pump wiring.
