about three weeks

it started before, the truck has 300000 miles on it but the motor was replaced 35000 miles ago with a ford crate full block.

what is seafoam? and where can i get it

i replaced the map sensor, plugs wires cap roter coil idel air sensor throttle pos. sensor fuel filter and oil about three weeks ago when all this starte.

could that be even if the truck only stall once in a 40 mile drive then maybe 2 or three times on a shorter drive, its real spuratic.... got me scratching my head.

i have a friend has a tool that pulls codes and even though the check engine light dous not come on we checked any way and there is no codes comming up

the pumps were changed because the front one was out for about 4 years, then the truck stsrted stalling and the garage said both pumps were out so i told them to chang them, the trans is an eo4 and the moter is a 5.0 302

and actually the stalling problem prompted me to get it looked at, and i was advised that the pumps were bad , but i still have the same problem

yes both tanks and the only other thing that was done about a month ago was a trans rebuild

i have a 1996 f150 2wd regular cab. about three days ago the fuel pumps were replaced both front tank and rear tank..... now the truck will intermittantly stall whill driving at different speeds from 75 mph to 30 mph when it stalls it will not fire for about 10 to 15 mins.... any...
