    Engine ticking

    So I have a 91 ranger with a 2.9l and I'm hearing ticking on the driver side of the engine. It ticks whether it's hot or cold. I opened the valve cover and ran it. All the rockers are getting plenty of oil. Any chance it's an injector. Just want to know the problem before spending money trying...
  2. Injectors not seated?

    Hi guys, new heads on a 1986 2.9L Bronco 2. The new injectors on the passenger side don't seem to sit as far down as the drivers side. We unbolted and rebolted the fuel rail a few times and we can't seem to get the passenger side injectors to go down any lower with or without the fuel rail being...

    Good evening, TRS. Haven't posted much here, so I apologize if I do anything wrong. What I've got: 1994 Ford Ranger 2.3L 5spd What the problem is: Fuel injectors are not firing.

  6. Stupid Injectors

    Ok, so I'm doing 6 new injectors on my dad's 99 Ranger 4.0, I have everything all set and ready to go, I'm following the instructions on All-Data for replacing the injectors, which says to place them in the fuel rail and then put them in the manifold, I followed a tip online and put just a dab...
  7. Need fuel injector expertise

    Hello, I need some advice from seasoned tinkerers. I cleaned my injectors like Dusty suggested on the RJM Injector web page. I soaked the injectors for two nights now and hooked up a test rig to blow them out and see how they were working in a general fashion. I used a short piece of tygon...
  8. 4.6l Mustang Injectors??

    I found a killer deal on 6 injectors with fuel rail and regulator all for $25 on CL in my area. Would they be a worthy upgrade for my 4.0 before I slap it in my Bronco II? Where can I find more info on how much fuel they output and such? I did some Googling but haven't found quite what I'm...
