It could be the fuel filter or the fuel pump or the regulatur or the main injector if you have throttle body injection . Start with the fuel filter if you have never changed it its likely time you did . Then when you have that off turn the fuel pump on and see how much fuel its pumping you should get 4 or 5 ounces in 5 seconds at about 60 PSI but if you get the volume you don't need to worry about the PSI

92 Ford F150 4.9L. starts good, idles rough, dies at slow speeds


4.9 litre ?? you having a laugh its a 10ton truck engine not a pick up -global warming machine,remove the pump/sender unit and check the gauze filter also look inside tank for a something floating around ,i think the idles is not a related problem to the vehicle losing power but their is a possibility you could have a problem with the little vac operated thing on the fuel injector line that allows the fuel through only when the engine is running

My 1990 ford f150 is smoking black exhaust what could be causing this?


Hello Warebaby.
Black exhaust indicates unburned fuel.
This can be caused by many things.
Bad ignition-spark plugs, wires, distributor cap, rotor, coil, ignition timing.
Excess fuel going in- bad injector, fuel pressure regulator.
Electronics-map sensor, throttle position sensor, oxygen sensor being most common.
Could be a good time to tune it up first

Hi got a ford f150 1986 f/i will not start


check fuel pressure @ service port on fuel rail. also listen for fuel pump to come on when you first turn on key. pump is in fuel tank. also note i have seen a lot of f150 302 injectors clogg up.but that usually effect idle and performance. if there is good fuel pressure then check fuel injector signal with a tester called a noid light. it is inexpensive and can be found @ most auto part stores. you really should'nt check injector signals with a standard 12 volt testlight. it has been known to burnout the drivers on the ecu. test all that first.

No power to fuel injectores


has to be a relay to the injectors. try to hook in your own hot wire to "jump start" the system.
