SOURCE: 1986 ford ranger sputtering and stalling out?

your having a weak spark issue you will need to remove your distributor to replace the pickup or the coil is breaking down sometimes this can be the egr but be careful removing this as not to break the intake hope this helps
p.s i had one with 2.9 and cured this problem on mine pick up in dist was weak but this could be emission also have any codes? good luck

SOURCE: fuel pours into cylinders

very strange and rare problem. something is keping the injectors open instead of pulsing them. The command to ground the injectors comes from the PCM, Powertrain Control Module. It may be a good idea to pick up a used one from a salvage yard. car-part.com is a good place to look. You will need the info off your module to match up.
Do you have 2.0L SPI engine or 2.0L Zetec engine?
Look on the page with the * to find the lowest price part.
aso, check for shorted wire going to injectors
---------------------------------------------

Mechanical Returnless Fuel System The fuel system consists of a fuel tank with reservoir, fuel pump, fuel pressure regulator, fuel filter, fuel supply line, fuel rail, fuel rail pulse damper, fuel injectors, and schrader/pressure test point. Operation of the system is as follows (Figure 62):

  1. The fuel delivery system is enabled during crank or running mode once the PCM receives a crankshaft position (CKP) sensor signal.
  1. The fuel pump logic is defined in the fuel system control strategy and is executed by the PCM.
  1. The PCM grounds the fuel pump relay, which provides VPWR to the fuel pump.
  1. The inertia fuel shut-off (IFS) switch is used to de-energize the fuel delivery secondary circuit in the event of collision. The IFS switch is a safety device that should only be reset after a thorough inspection of the vehicle (following a collision).
  1. A pressure test point valve (schrader valve) is located on the fuel rail. This is used to measure fuel injector supply pressure for diagnostic procedures and repairs. ON VEHICLES NOT EQUIPPED WITH A SCHRADER VALVE, USE ROTUNDA FUEL PRESSURE TEST KIT #134—R0087 OR EQUIVALENT.
  1. Located on the fuel rail is a pulse damper. The pulse damper reduces fuel system noise caused by the pulsing of the fuel injectors. The vacuum port located on the damper is connected to manifold vacuum to avoid fuel spillage in the event the pulse damper diaphragm were to rupture (the pulse damper should not be confused with a fuel pressure regulator).
  1. The fuel injector is a solenoid-operated valve that meters the fuel flow to each combustion cylinder. The fuel injector is opened and closed a constant number of times per crankshaft revolution. The amount of fuel is controlled by the length of time the fuel injector is held open. The injector is normally closed and is operated by 12 volt VPWR from the power relay. The ground signal is controlled by the PCM.
  1. There are three filtering or screening devices in the fuel delivery system. The intake sock is a fine, nylon mesh screen mounted on the intake side of the fuel pump. There is a fuel filter screen located at the fuel rail side of the fuel injector. The fuel filter assembly is located between the fuel pump and the pressure test point/schrader valve.
  1. The fuel pump (FP) module contains the fuel pump, fuel pressure regulator and the fuel sender assembly. The fuel pressure regulator is attached to the fuel pump in the fuel pump module located in the fuel tank. It regulates fuel pressure supplied to the fuel injectors. The fuel pressure regulator is a diaphragm-operated relief valve. Fuel pressure is established by a spring preload applied to the diaphragm. Excess fuel is bypassed through the regulator and returned to the fuel tank.

Electronic Returnless Fuel System The fuel system consists of a fuel tank with reservoir, fuel pump, fuel rail pressure sensor, fuel filter, fuel supply line, engine fuel temperature sensor, fuel rail, fuel injectors, and schrader/pressure test point. Operation of the system is as follows (Figure 63) and (Figure 64):
  1. The fuel delivery system is enabled during crank or running mode once the PCM receives a crankshaft position (CKP) sensor signal.
  1. The fuel pump logic is defined in the fuel system control strategy and is executed by the PCM.
  1. The PCM commands a duty cycle to the fuel pump driver module (FPDM).
  1. The fuel pump driver module modulates the voltage to the fuel pump (FP) to achieve the proper fuel pressure. Voltage for the fuel pump is supplied by the power relay or FPDM power supply relay. (For additional information on FPDM operation, refer to PCM Outputs—Fuel Pump and PCM Inputs—FPM.)
  1. The fuel rail pressure (FRP) sensor provides the PCM with the current fuel rail pressure. The PCM uses this information to vary the duty cycle output to the FPDM to compensate for varying loads.
  1. The engine fuel temperature (EFT) sensor measures current fuel temperatures in the fuel rail. This information is used to vary the fuel pressure and avoid fuel system vaporization.
  1. The fuel injector is a solenoid-operated valve that meters the fuel flow to each combustion cylinder. The fuel injector is opened and closed a constant number of times per crankshaft revolution. The amount of fuel is controlled by the length of time the fuel injector is held open. The injector is normally closed and is operated by 12 volt VPWR from the power relay.

The problem is most likly the sending unit in the fuel tank but check the float. drain tank, there are two bolt in the straps on the fuel tank lossen enuf to lower tank to get to top to unplug wires and fuel lines once tank is on the ground thee is a ring on the top of tank holding the pump and sending unit in tap ring around with a screw driver to lossen once you have that off just pull unit out of tank and follow directions that come with sending unit. reverse removal procedure. good luck.

remove the coil pack and look at bottom of it if it shows any cracks coil is bad very common on these vans if you have a noid light check for injector pulse on #4 if you have pulse and good blue spark most likely the injector is bad you have to remove upper plenum to get injectors out let me know how you make out

Is this a 4.9L engine? An inline 6? My database doesn't show a 4.9L in that model year. It does show that engine in 95.
Did you visually check for spark at number 4 cylinder?
For 95-- 4.9L--fuel pressure--50--60 psi. Use a gage and check proper fuel pressure. Also, see if fuel pressure will hold for a bit with everything off.
Fuel--spark--compression. Some ford makes and models, ford can disable the fuel injector, if misfire is detected. I only mention this because, swapping injectors may not be conclusive? You can check for fuel injector pulse, anyway.
How long since over-all tune-up? You did get a new fuel filter, if inline filter, correct?

You might have what is called vapor lock. The fuel gets so hot that it boils in the fuel pump or the lines. Do this test spay water on the fuel pump to cool it off . ( this only works for a few minutes before it gets to hot and vapor locks again ) If you can Keep the engine heat Off the lines and the Fuel pump it might help. If you have metal fuel lines near a heat source rap them with something such as rubber fuel line sliced down the middle to keep the heat off them If you are using an aftermarket electric fuel pump relocate it down low near the gas tank ( they work better pushing than pulling ) away from any heat source such as exhaust If your using the stock fuel pump try replacing it with a new one it might be getting weak Replace the fuel filter while your at it.

What is the firing order for a 1984 ford bronco 2


1-4-2-5-3-6
Now you need to know which cylinder is which. If you stand at the front of the truck looking at the engine, the number 1 cylinder is on the left closest to you. The left bank has cylinders 1-3-5 and the right bank has 2-4-6. So number 1 is at the left front and number 6 is at the right rear.

well first of all, it's a good thing you're draining it, because there's rust in your gas tank. Second, you're going to have to siphon the gas out, and third, use a proper technique, because i doubt that gas is too tasty

Check for timing gear problems. They have plastic teeth on the cam shaft gear which will shatter causing it to jump time.
