Fuel Pressure Problem on my 1996 Ford Explorer (4.0 V6)

My Explorer seems to be having trouble Starting once or twice a day. When it happens you have to release the fuel pressure from a valve on the side of the head. My check engine light is on due to a Faulty or dirty O2 Sensor. Could the O2 sensor be the source of my problems?

Sounds like the fuel pressure regulator is going bad...this will cause the fuel pressure to be high and create a flooding condition. Which in turn will gas wash the motor and contaminate the O2 sensor with excessive fuel. Check fuel pressure with a gauge at the valve you are using to relieve pressure. You can find pressure specs on-line for that particular vechicle. If pressure is high...replace regulator, O2, change oil and reset computer by disconnecting battery for ten minutes...

Is this car fuel injected? If so there shlould be a flow sensor somewhere on the intake . Many of the patrs stores will loan an OBDI or II and you could do a diagnosis on the engine. This should indicate a faulty flow sensor among other problems.
Lots of luck.
I have the same year, model and engine with Automatic tranny, This was the year the Explorer replaced he Bronco and there seems to be a bunch of prototype parts. I just replaced the headlight/turn signal multifunction switch for $185.00. :(
Not a lot of information about this year. But it is a fun car :)

Have to spray starter fluid in the intake to get to start. once started runs fine, why?


This sounds like a weak fuelpump, and take a while to build up pressure, the starting fluid get the engine running until the pump builds up pressure, i would have the fuel pressure tested and i think you will find that its bad. good day.

if the pump has been changed twice its probally not the pump. could be the fuel pressure regulator. the computer will still throw a fuel code but in order to really diagnose the problem they would have to test the fuel pressure.

or
Go get an inline spark tester. (Harbor Freight 3 bucks) If there is spark in the plugs then it is probably the fuel pump. Check\replace the relay first. If that not it then your fuel pump is probably bad. If you know how you can check the fuel rail pressure with a gauge to see if the pump is working. You can try to listen for the pump. You have to listen real close. Get inside the vehicle (close the doors)and put your ear to the floor in the cargo area. Have someone turn the key to the second click right before starting it. You should here it pressurize the fuel lines. If you done hear this then your fuel pump is bad. I hope this helps.
