Okay, so my truck broke down last night. Here's what happened. Monday I was driving down the expressway, stopped, put fuel in it and started back down the road. The truck started running like it was in a little bit of a strain, it still ran good though so I thought maybe some bad fuel. I drive to the office and back yesterday, same thing but when I pulled in to the neighborhood it suddenly started missing really bad, and there was a loud whine, kinda of like a power steering pump makes. Could it be the HPOP has gone out? I've been told I would probably be replacing it soon, it has around 166k on it. I also noticed over the weekend it had a small oil leak coming from back of the engine but looking online I read several places that said it is typical for an oil leak on the pump to make it's way back there. So what do you think? I changed the fuel filter when we upgraded the injectors last month too. If it is the pump, should I go stock or aftermarket and which one? I don't plan on upgrading anything else to make power, I like the truck just like it is.
Ended up being the fuel pump. Quick fix.
