temp gauge

I have a 94 Silerado with a 5.7 and the temp gauge has stoped working i have replace the sendor about four times and it works for one or two day and stops again put new one in and it work again for a few more days.Next i"am going to replace the wirehaness plug .
Does any know whats going on Here.
Thanks Jim

It could be a bad guage, but i wouldn't think that this would kill a sender. I would honestly think about just installing an aftermarket mechanical gauge or electrical guage. These tbi's aren't as computer enhanced as the later 350's so you should be alright doing that.

Thanks for the info
