  1. 2.3L ('83-'97) Fuel Pressure Bleeding Down

    Hello all, I'm currently in the middle of a distributed turbo 2.3 conversion from a 1988 Thunderbird Turbocoupe into my 1991 Ranger, which had the EDIS 2.3 stock. I am running into a bizarre issue where the fuel pressure is bleeding down after letting the fuel pump prime the engine. I have done...
  2. No Fuel Pressure and No Start Condition

    I have an 86 Bronco 2, It was unable to turn over and the mechanics had told me there was air in the fuel lines. after getting it back it was parked for 4 hours and then would not start up again. Am I correct that in the on position the Schrader valve should produce 40 PSi of fuel pressure...
  3. Rough Under Load - Fuel Smell - No Codes

    Truck starting jerking a little a few days ago at highway speed and then continued even at low speed. First thought was bad fuel pressure or blocked fuel filter. While driving/under load: Heavy vibration and sometimes jerks/bucks. Feels drive train related. At idle or rev up while in...

Mine is the plastic spacer (~3/16" thick) sandwiched between 2 thinner gaskets (paper I think, don't have them off yet). I have the intake...

  7. Fuel Flow Problem

    A few months ago I swapped out the fuel pump as well as the fuel filter due to a no start situation and a verified no power to the fuel pump. Ever since this time, when I get below a 1/4 of a tank I have problems with idle when coming to a stop. Sometimes, it will die and other times drop to...
