I have a 1994 Ford f-150 and have been having some issues with it starting. When it starts it warms up then wants to miss fire. I worked with it and got it running again and decided to give it an oil change and put motor flush in it. Now the fuel pump in the front will not give the buzz but the rear tank does. Still everything I do it will not start. If you put starting fuel id in it will run.
What the heck could it be? Fuel pump? If the rear tank works wouldn't it get gas to the engine if the front tank fails?
