This was a set I pulled out of a customers truck. He just got these rebuilt with only a few miles on them but was giving him a hot no start issue. Narrowed it down to something with these injectors is causing it. The guy who rebuilt them is not calling him back and customer got screwed. So I'm selling them for him as a complete set of cores! They will run, drive, and idle perfect, but once the oil gets hot it will not restart. I know this for a fact because I put brand new ones in his truck and it's back to normal. Again, set of cores. Everything exterior wise on these injectors is A1. I'd recommend having these rebuilt again and checked out. Let the builder know about the hot no start issue and maybe it's something easy.
