Message: [QUOTE="Lt.Dan, post: 1453267, member: 24137"] Hahaha, good point! So i actually got the pump today, i didnt get a tracking number until today, but it was shipped out a few days ago. So I received and installed it today. The install went great, and I got everything back together perfectly. Installed the IPR just as it came apart, all the O-rings looked to still be in good shape. Torqued the HPOP gear bolt to 95 ft/lbs. Motorcraft RTV on the inspection plate, hooked up all the fittings good, etc. I didnt have a funnel to fill the hpop reservoir, and didnt want to spill it everywhere trying to pour it in. So I opted to crank instead of fill. I used the starter relay on the fender and jumped the 2 posts to crank the motor. Did 2 cranking intervals, of about 30 seconds long each. Then jumped in the truck, primed the fuel system, and cranked for about 10 seconds before it fired up. It ran HORRIBLE at first. Sounded like it was mis-firing, running on 6 cylinders, and loping super bad. Put it in high idle for about a minute or so, and then decided to jump in and just cruise around the block. Some major air in the system, but it got better the more i drove it. Drove it about a mile, varying in load/throttle position/ and speed. It was super fun! Felt like a totally different truck! I only had it in stock mode on the tuner, so I didnt get to actually romp on it, but it felt like it ran much stronger. Then I cruised back and parked it, it was still choppy but nothing near as bad as when it first started, so I figured I would run it harder on the way home. I shut it down so i could close up shop and drive home. Spent about 10 minutes closing up, went back out, and now its a no start! I probably did 30 cycles of 20-30 second cranking intervals over a 45 minute period, Its not a battery issue, or a slow cranking issue, I have it jumped with cables to my other truck, and a big battery charger on it at the same time, It cranks like hell. I triple checked every sensor, its all hooked up correctly. I tried pulling the ICP sensor harness in hopes of starting, no difference. Checked the HPOP reservoir several times throughout, and every time I checked, oil was at the TOP of the reservoir, couldn't add a drop if i wanted to. And with my scangauge II i was able to check ICP pressure and IPR duty cycle. ICP gets up to 2700psi, and IPR hovers around 34%. CPS is good, I get a solid reading on the Tachometer, and its a new CPS from ford (came with the rebuild kit, maybe 500 miles old). I also have fuel pressure with the key on, a solid 65psi (although it does sound quieter than it usually does). While cranking though, I cant tell, I cant be in 2 places at once lol. Hell I even tried to start it with spraying some WD-40 in the intake to act as ether, no change. Getting a small amount of white smoke out of the exhaust. Its hard to tell with no exhaust (I only have the downpipe installed), but after cranking I can crawl under there and you can see faint smoke still coming out of the pipe. It also has a very strong smell of exhaust. So i only have a couple theories, 1) the HPOP gear bolt needs to be retorqued, but I would think with it loose, I wouldn't be getting any ICP readings. 2) Fuel pump is worn out from all the abuse I've put it through, using it to fill empty filters, etc. 3)???
