Message: [QUOTE="Tiha, post: 1564074, member: 33189"] Of course warranty is not going to be easy. Spent some time on the phone with the supplier. Went through all the troubleshooting I have done. All he wanted to know is the code I am getting. Which is P2291. Injector pressure low while cranking. He says, before we swap the pump. I need to check a few things. I hate this, I knew warranty would not be easy but that is also why I went through so much troubleshooting already. The things he said to check, check for oil leaks. Not sure how that applies, but I have no oil leaks. He wanted me to do an oil change. I will think about that one. VCV, which he kept calling the pressure regulator, Check, I put a new one in, he was happy with that. He said they do come dead out of the box frequently. Wiring, I did check that and he was happy with the testing I did. PCM, same, he was happy with the testing I did. Now the Pressure sensor on the rail. He says I need to change it first. And of course he threw in that i should have done that already. He says that is almost always the problem. Yeah heard that before, but I hope he is right. When I unplug the rail sensor, pressure reads 29,000 psi on the scan tool. I asked, shouldn't the truck start then? He said it might but normally no. That doesn't really make sense to me. But okay, now I have to jump through their hoops. Maybe I will get lucky and it will run. google found exactly what he was telling me.

But even more interesting, that link takes me to a 6.4 page Another thought, this sensor is new and reads exactly the same as my old sensor. So either I would have 2 bad sensors or a wiring issue. Which I have no idea how to check yet. Need to dig into that and find a diagram. [/QUOTE]
