Re: 1995 GMC Sierra 5.7 liter stalls and is hard starting...
Even though parts are new they also come with defects so it sounds as if when you turn the key you hear it working and other times not at all hmmm connections are tight ? could be faulty fuel pump or relay .
Thanks for the reply. This truck was doing this prior to me replacing these parts. It ran great for 6 weeks and now it happening again. I found a small gauge red wire under the fuel pump relay that was dead ended with a spade connector near the firewall under the fuse box (under the hood). i secured it so it wouldn't touch anything. I would like to know what the red wire is intended for.
