GM used a connector for the fuel pump that had small contacts. It is susceptible to failure due to corrosion of the contacrs. We sell a replacement pump that comes with an updated pigtail with larger connecting pins. This video show simply the process to replace the old plug with the new one.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
GM used these very small connectors and they were susceptible to problems. Most of our new fuel pumps come now with a different connector that has larger contacts. You basically have to cut the old connector off. You couldn't leave it on there. Cut the old connector off.
It comes with a new connector, which is all color coded: purple, gray, black, black with white stripe. So, we've cut these four off and we'll strip about a quarter of an inch off. Then these connectors are two different sizes. The blue ones are a little larger, so I'm going to use a blue one on the gray and the black wire. I put the connector on. There's metal inside. Make sure the metal gets down over where you've stripped, crimping pliers. I actually put the pliers on. Now take the wires and match up the colors and push them into those splices. Then just clamp it to lock the wire in. We'll fast forward as Mike does the rest of the wires.
Now wrap those splices in electrical tape. On some cars . you'll notice on this Monte Carlo that we did this procedure on . there will be posts in the way of this harness and you will have to remove one of those posts so that you can fit the harness in there.
