1994 Ford F-150 Repair Question
Mileage: 200,000 miles.
Ford F-150 Fuel pressure Problem
Also If I press hard on the accelerator sometimes it will pick up and run ok. But not always. It could slow down to 10 mph.
I am not sure if the problem is fuel or some censor.
I have been unable to read the codes by jumping STO to STI ...

I disconnected the Mass Air Flow sensor. It did not seem to backfire anymore thru the carb And ran ok-- though with hesitation.
I also managed to read the codes:
1. They seem to be 3 slow flashes, -- twice.
3. Then one flash
4. Then 1 flash
5. then 5 flashes (rapid)
6. Then 7 flashes (rapid)
7 then two the flashes
8. then 1 flash
9. Then two flashes
10. 1 flashes
11. 5 flashes
12. 7 flashes (rapid)
13. 2 flashes (rapid)
14. 1 flashes
15. 2 flash

They did not have the tool. I can borrow it tomorrow in the morning.(may be from another branch).
I hope this is something to go by.
