Dear Tom and Ray,
I have a 1994 Ford F-150 pickup with a 4.9 litre fuel injected inline six. Truck ran fine and took me to my destination but after sitting for 4 hours the truck would not start. Engione would tur over normally and could hear fuel pump running(didnt seem to stop) but truck would not start.
I changed fuel filter but truck would still not start. I removed air filter assembly and poured starting fluid in the air intake and engine started but idled roughly. Engine will rev up but runs very rough and lacks power when driven. Also th check engine light stays on.
Would appreciate any input as t what would cause the problem and what a possinle fix could be.
