fuel system
 

long question made short......po190/po191 changed fuel filter, mud out, cleared codes, run good, stalled out, checked filter has clear gas, replaced fuel pump, has power to fuel pump til plugged into fuel pump, please help!!

Have you checked the fuel pump driver, mounted on cross member behind spare tire?

Not sure how to do that can you please tell me

What truck do you have? Later models have a fuel pump driver module as stated above. First, lower the spare tire and look at the device. If you see any powdery corrosion on the aluminum lower plate, you may as well get a new one and install it. Search this forum for it and you will see some excellent pictures posted of bad ones.

Thank you all that was the problem. FYI the pump was original...2003, truck is 2004. lots of gas went thru that baby. Thanks again for your help. My Ford is up and running again.:-jammin
