02 psd code p1211

[smagma]

Engine starts quick and idles smooth. Engine from idle to WOT seems to gurgle as the rpm's rise. With intercooler tube disconnected the engine will not rev over 2800 rpm and bellows white fuel smelling smoke from exhaust. Under full load the engine seems to stop pulling, like no fuel. I did monitor the fuel pressure and it drops to 0 psi under heavy load, the IPR goes 65%, ICP goes to 2200 psi and then the p1211 code will set. I've tried an IPR, fuel pump, changed oil, ICP and fuel filter. I know what P1211 means, I just don't know what is going on.

was the fuel pressure test before or after the fuel pump replacement , ipr will ramp up high if fuel pressure is low

fuel preesue was checked before and after fuel pump was replaced.

if the fuel pressure is dropping after pump replacement then, you probably have a restriction in the tank causing the pressure to drop

did an injector leak test yesterday and found nothing. the problem seems to occur after the truck is driven or the engine is warm. i was thinking there could be something in the pickup strainer in the tank, but it runs good other than WOT.

sounds like fuel pressure to me , pull the tank, remove the sender ,and clean the 2 filters in the end of the sending unit

If you have a restriction in the tank or at the pick up theres a simple Mod you can do to fix it. John Woods did it to my dads truck the other day. Its called the "Hutch Mod". Go to "7.3 Tech Files" Click on "Alot of Mods" Click on the link, Click on "Engine Drivetrain Mods" click on "Intake Fuel System Mods". This is a simple mod that will eliminate the restriction problems commonly found in the tank pickup.Good luck.

If you're going to drop the tank do the hutch mod in 7.3 tech section under Lots of Mods by Maintain while you're at it. I eliminated the mixer completly.

just dropped the tank and found big paint chuncks inside. the pickup screen had a few pieces in it, but not enough to cause a problem. did notice the plug in the side of the pickup in the bottom of tank. could have sucked a piece of paint into fuel pump. the pump does hum, but whatever.

it is the tank. pulled the pickup assy apart and was full of paint. delamination is the word. the dealer has 4 tanks in stock, say they sell quite a few. after i replace it i will let you know how it runs.
