Hey there guys... here's my situation. After having no problems I parked in front of my work. Came out for lunch and truck would not start. This has never happened with this truck, always kicked right off. I had my truck towed home, and trouble shot what I thought was the Raptor liftpump was inop, as no fuel was getting to the VP44. Had them send me a new pump as this was in warranty, and I installed it yesterday. I got the truck started, and thought everything was OK. Went to drive it about an hour later and had to crank it for probably 20 seconds before it started rough, then smoothed out. I was going to go into town with it, but as I was driving there I thought better of that and decided to drive it back home as maybe it wouldn't re-start. Sure enough I got home, shut down and it wouldn't restart. I troubleshot the Raptor, and discovered that it was not delivering fuel to the VP44 (FYI this happened several years ago with one of these pumps, stopped functioning within a day, so I had it in my head that this was the issue). Cranked the engine over and felt for suction at the inlet of the Raptor, only suction was when the engine was cranking, i.e. the VP44 was pulling suction through the Raptor, and the Raptor wasn't working. I should add that I could tell that the Raptor motor was running, could see and feel it. So I called Indiana and they suggested I prime the Raptor with motor oil, which I did and did get it to pump fuel to the VP44. I primed to the VP44 and could not get the truck started. I have confirmed that there is fuel to the VP44 inlet, and have pulled the following codes: P1698, P0216, P1693, P0602, P1687, P1694, P0500. I know that some of these are thrown from using the Smarty, which I have set back to stock in the process of troubleshooting this. After clearing the codes I again tried to prime the VP44 by Mikes process, cranking for 30 seconds at a time and then letting the starter cool off. No Joy. Checked for codes after this and have none. I'm leaning to the theory that the fuel starvation caused by the Raptor not pumping has fried the VP44, and that when I started after first replacing the Raptor, the VP44 was pulling fuel through the Raptor and caused the failure. I know there is a lot of experience with this stuff out there...can anyone shed some light on this before I go buy a rebuilt VP44? Thanks
