My 1993 ford f150 4.9 inline 6 stalls when you accelerate fast. it has a new fuel pump,fuel filter,pvc valve,spark plugs,air filter, and spark plug wires. i also cleaned the gas tank. it idles great and takes off in gear ok, but when you get on it,the check engine light comes on and the motor loses all power like its choking. when you let off the accelerator for a few seconds the motor recovers.

What engine code is stored in the computer? You may have a bad TPS (throttle postioning sensor), or a bad O2 sensor. Auto Zone can retrieve the code for you, and tell you what sensor it is related to.

Have you checked base fuel pressure with a gauge ? You could have been sold the wrong pump, or the inline filter may be clogged.

does the car start and idle?

If so, replace the fuel filter - being you put in a new pump, then filled the tank, driving to the station may have caused seditments to get into the filter and plug it up.

Also, find your MAS (mass airflow sensor) and with car running, tap on it with a screwdriver handle (or small tool) -- if the car dies, or stalls, (idle fluctuates; more so than while just idling); you can first purchase MAS spray cleaner - remove, spray inside (honeycome) generously, let air dry for 15 or 20 minutes; install and start engine - tap again with small tool, and if it still dies, stalls, or fluctuates, replace the sensor (MAS).

Also, make sure that if you already installed a new fuel filter, that it is facing in the right direction. On most (inline {near tank} filters}, there is an arrow that should point toward the front of the car (or if mounted horizontally (from one side of car to other, facing both directions) make sure the arrow is facing the driver side.

Please let me know if you need further assistance.

Car wants to stall when i go to accelerate..


There are some  possibilities that has to be checked in this case. 1) Sounds like a fuel delivery problem (possibly fuel pump) or a clogged fuel filter. Try checking the vacuum lines. 2) The other thing to check is the fuel pressure 3) The  problem is related to fuel.Either their is very less fuel or there is proper fuel but there is dust in the fuel tank which got mixed with the fuel and that is got blocked in the fuel filter and making it stall. 4) Get all the three things checked The fuel pump,The fuel filter and the fuel. Also check if the fuel pump is properly connected or got worn out and loose.
Thanks. you can rate this solution and show your appreciation.

sounds like a clogged fuel filter or a fuel pump that is not delivering enough volume .. they had some trouble with fuel pumps about that year but not sure on the f150 .. if you let the fuel level get too low then it would overheat and damage the fuel pump ... here is instructions on testing the fuel pump.:

regulator most likely. Need to check fuel pressure both when running and after a stall. My guess is 20 lbs when it starts, 0 after it stalls. Replace that fuel filter also.
