Looking into fuel quality Thx Larry

For all practical purposes symptoms are the same with recon IP. Truck is stock no mods, replaced Lift pump with stock replacement. Did try the water hose over IP with no change Used OBDII scanner, does it need to a special one? Also read codes through odo key on 3 times Thanks for the replies

Have a 2001 24 valve auto trans 25000 miles. Died on road, towed to shop, checked codes-none. Lift pump not working, put pressure gauge on and 0 psi. Remove pump and benched test pump inop.Replaced pump, bleed system and have 12 psi started up. Will run fine, actually very smooth till warms up and then hunts and stalls. Can restart and hold throttle but if left to idle will stall. Let cool down and starts fine and repeats when warmed up. Has 12 psi to pump when stalls, put clear line to see if air entering pump ok. Ended up changing VP44 pump, injectors and distribution tubes, changed Tee fitting on return with compression and real brass ferules. Seems like when it goes to closed loop problem happens. Checked coolant temp sender when stalls has back probed about .9 v. Would appreciate any help or suggestion Thanks in advance Larry
