Message: [QUOTE="ghohouston, post: 1091858, member: 9421"] as many of you may know, i am a fleet mechanic for a company with over 400 powerstrokes, and am beyond familiar with them. Now, to my 97. My ignition was broken, and long story short, ignition was left on overnight. Truck was dead next day of course, used my 6.0 work truck to jump it off. It took some cranking, but finally started. Ran bad, then died. Facts: Checked all fuses, and double checked them. All were good. ipr is at 15% duty cycle koeo, maxes out at 65% while cranking, reaching 3000 psi icp while cranking, and cranked with icp unplugged, no change. oil level physically checked, and have oil pressure on the dash(duh) cps swapped out with brand new ford unit, no contact marks on old sensor cranking rpm's show on tach, and verified on scanner buzz test passes, and all 8 buzz loud and clear removed chip, and re installed pcm, still no start WAS throwing po603 and 605, which is expected, i swapped batteries with my work truck, and it does have a gearhead chip. i am not getting any codes now. i currently do not have a fuel pressure gauge, and i have a super duty fuel bowl/hpop res/fuel pump, so no schrader valve anymore. however, if i open the drain valve with the key on, it certainly appears to have good pressure, but i do understand this is not a good way to determine fuel pressure. I have gotten the truck started several times since, but only runs a few seconds, and very poorly at that. then dies. i tried flooring it for the hell of it last time i got it started, and it wouldnt go above 2,000 rpm's. Im getting frustrated with this thing. It's always my own vehicles that have the most god awful issues. So if anyone has suggestions, please send them my way. My only theory is i seriously damaged the fuel pump leaving the key on overnight, and not having the pump wired where it cuts off after x amount of time, and (dont kill me guys, i never drive this thing, but its not fused yet either). Other thought was maybe uvch, but it buzzes fine every time [/QUOTE]
