Question about 1990 Ford F150
Posted by Anonymous on
I think you need to replace the front fuel pump it has a bad check valve in it. Check with Ford there is a tech bulletin written for these and they have a modified part for repair. I hope this helps, Take care. If you have more questions for me use testimonial and it will show up in my email. Thanks

It could be the mass air flow sensor. Its mounted to the side of the air cleaner. Just unplug the electrical connection to bypass the unit. If this is the problem the vehicle should run smoothly.

This is not a solution , just a clarification. Did you change the fuel filter and put it back on in the correct direction or is the fuel line beyond the pump producing gas?
