Fuel flow problem

Asked by JamesB47 Mar 14, 2019 at 04:51 PM about the 1989 Ford F-150 XL Extended Cab LB

Question type: Maintenance & Repair

I have a 1989 ford f150 4.9L 6cyl with duel tanks. I am getting fuel all the way to fuel injectors, but not into the cylinders. I have replaced fuel pump, fuel filter, fuel relay, fuel pressure regulator, fuel injectors and EEC. Does anyone have any idea why it is still not getting fuel into the cylinders? .

I replaced all the fuses under the dash. If the injector fuse is in a different place, than I have no idea where to find it. I'm doing this myself because I can't afford a mechanic and have to have transportation. I don't have a tester light, and can't get the truck towed so I have no Idea if its getting pulse to the injectors.

  • The rear fuel system isn't working right. Seems like it's not receiving a good flow of gas. And I can hear the pump struggling. Can you tell me, what's the problem? 1 Answer
