Message: [QUOTE="cbuttre835, post: 500864, member: 1190"] Sorry, this got long winded. Backstory: I got some bad fuel in the front tank at some point. Bowl would be full of rust; I'd drain it as often as once a week, whenever the WIF light came on. Truck always ran OK. Till one morning on the way to work; it quits. Quickly; like an electronic die-off. I thought CPS; replaced it with a NOS IH CPS, still same problem; got a brand - new one from Oreilly's; that appeared to fix it. Thennnnn, it almost quit again. While running on the front tank. I was down to a little less than 1/4 tank so I hit the switch. It stumbled and missed and smoked and popped for a 1/2 mile or so then cleaned up. Bad fuel, I said to myself. I made it home and parked it and gathered parts for a Bronco tank swap. Truck also had a fuel pump leak for about 2 years, so I replaced that. Replaced o-rings in the bowl. Installed the Bronco tank; filled it with clean fuel from a can, I ran it for 20 min or so in the driveway. Ran great, no leaks. Woo-Hoo.:redspotdance::D I noticed it being hard to start the first couple times, but since I had the banjo bolt off and fuel pump replaced I chalked it up to air. I also noticed when it starts it doesn't really "hit". It sounds almost like a roll start of a manual clutched truck. It quit again tonight, a half mile from the house. Acted like a gasser starving for fuel. No CEL, tach looked fine, just "choked" down. I let it sit for 5 min while I contemplated stuff like how much it would bring for scrap metal. I remembered my half-throttle trick when the IPR died, I got it started (a sluggish, lumbering start) by cranking for 8-10 sec at half throttle and hammered it on back home. Fuel pressure on the schrader valve is fine (45 PSI) when the truck is running. ICP duty cycle looks "normal" 11-13% at idle. EOT is wierd... like 350 degrees. But the other truck has always done that on my cheapo Palm scan tool. I"m at the end of my rope and asking for suggestions. Plan at this point is to re-rig my "live" fuel pressure gauge and zip tie it to the antenna or something so I can read it constantly while driving; and maybe do the same with HP oil press (I have a 5k PSI gauge and 5K psi working pressure hose, that should suffice?) Any other thoughts? Acts just like a lawnmower or something you "choke" down. :lookaround: TIA. [/QUOTE]
