Asked by tstansbro Apr 13, 2012 at 10:14 AM about the 1989 Ford F-150

Question type: Maintenance & Repair

I have a 1989 Ford F150 with the 5.0 fuel injected. Its not getting gas and I don't know where the problem begins. I know its getting fuel up to the fuel pump by the driver's door. but not sure about afterwards. Is there anyway I could rig a gas can to it so that it'll get fuel directly too the motor and I could get it to run? Like on the older model fords that have the fuel pump on the driver side of the motor? Or is that not possible with the fuel injection?

check all of the fuel lines and go to a parts house and get some Lucas and clean out your fuel injectors, and if that doesnt work then look into a new fuel pump

I also have an 89 ford f150 with the 5.0. Before spending a lot of money, jump the wires to the fuel pump just inside the frame rails under the driver door. Several fords that I have worked with fail at the relay controlling the fuel pumps, fore and aft. (You have two pumps, one on the rail and one in the fuel tank.) If the pump powers up, replace both the relay and the connector. Corrosion will cause the relay to fail.

Where are these wires at? And what colors are they?

I also have a 1989 f150 five speed straight 6. I just changed the fuel pump and the filter and after driving half the day it sputtered and died out I poured a gallon of gas in the tank hopping it was out and it started right up only to die out again after about 5 miles and now it wont start. Would you know what it may be and how to fix it?
