Hi Jeff, depeding on where you are using the vehicle and the quality of the fuel used, you may be having problems with the injector nozzles or more than likely a defect on the throttle position and throttle operation sensors. Have the vehicle scanned and that will point out any electronic defect, but not a mechanical problem. As you have not given very many details and omitted the year of manufacture, we do not know if the vehicle has an electronically controlled gas pedal or a cable operation.If it is the 1HZ engine the problem may be connected to the head and rotor fitted to the injector pump.Give us more details and we in turn may be able to give you more help. Regards John
What you replaced is the APP(accelerator pedal position) It is part of the electronic throttle control,what was truly needed is know as the TAC MOTOR. This recieves signal from the APP.The TAC is what accelerate the car.The only thing you can do other than replace the TAC,is do a TAC relearn .Turn thhe key off. wait ten seconds,Turn key on with the engine off.leave 1 minute. Turn key off start the vehicle you will hear the TAC motor setting itself.
did u use fuel stabalizer? if not the gas can turn into a varsale like substance that can clog fuel filter and reck injector seal's, also check the disributor cap and rotor for condensation, this can happen over a period of sitting
I am not to sure but I know that there is a process called the "Relearn" which mainly zinchronizes the throttle body with your ECU... But I am not to sure for a ford exactly I know that for a Nissan if you getting code P0507 the relearn Process will follow as: 1. Warm up the car to normal temperature of drive it for a few minutes and turn it off. 2. After you shut off the engine wait ten seconds. 3. Turn the Key to the ON Position but don't start the car. 4. Wait 3 seconds and press the gass pedal and release 5 times in whitin 5 Seconds. 5. Give it a 7 seconds and press the gas pedal and keep it pressed for about 10-15 seconds and the engine light should star blinking for about 15-20 seconds as soon as it stops blinking start the engine let it run for about 20 seconds and rev the engine up a couple of times then you can shut it off.
But I had a couple of time in which a rebuild piece might fail to sync with the relearn process...You might need to go with a new part....Good Luck. I am kind of sure that Ford migh have a forum those sites are very helpful because of they are Ford Vehicles owners that will post their solutions to similar issues.
Make sure you have a good connection between your starter and battery cable to the battery. Also check your ground connection from the battery. Your battery is the source of power that kicks the starter to turn. So just follow the battery cables to be sure they are clean and have a good connection.
Check the throttle. Make sure it isn't sticking shut preventing air from getting in the cylinders.
Are you getting spark? If the spark plugs aren't new, pull one out and look to see if it is bad. If it looks pretty crummy, replace them and try again.
Check to make sure the distributor and wiring harness to the spark plugs aren't falling apart or disconnected.
Check the compression in your cylinders.
Check the gas flow
You need spark, gas, and compression (involving air) to get a turning over vehicle to fire up. Check all connected with these, testing with each change, to try to isolate the problem. Those listed above would be my starting point. It looks like a relatively new vehicle, so i would start with checking the spark plugs to see if there is anything awry with your cylinders (this spark plug diagnostic chart could help http://www.ingfatrygg.se/Spark_plug_diagnostics.html )
It could be a couple things. There may be a vaccuum leak in the fuel system such as a bad EGR or PCV valve or the throttle position sensor. I'm leaning towards the throttle position sensor needing replaced. The throttle position sensor reads how far you're pressing on the gas peddle and then feeds that to the computer telling it how much gas to feed to the engine. If that sensor isnt working right then your car will get enough gas to start and idle but will starve for gas as soon as you try drive and will then stall.
