Top 20 2006 Ford Super Duty F 450 Drw Questions & Answers

There is no shims to reduce the backlash in a diff. The backlash comes from incorrect thrust washes behind the side gears . They wear and allow the tooth clearance to become excessive . Using new washes will bring the backlash back into specs.. Check bushes in the gears and shaft condition that the gears are mounted on.

check your brake light bulb at the back or the brake switch needs to be replace..

have tryed the fule pump is working

Well, they're not related, unless they share a common ground, which may be behind the driver's kick panel, or under the dash somewhere.

Make sure it has plenty of oil. Low oil level will cause injectors to not fire. Change fuel filters > small one on top and big one on frame rail..

Purge air by leaving engine filter loose. Fuel should come squirting out once key is cycled, if not tank could be stopped up.

I'm hoping you are able to see this. If you need an owners manual for your truck just email me at [email protected] with your make model and year and I will be happy to email you a copy. Don't worry no cost or any of that stuff. Here's your diagram. I hope it helps and good luck.

A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the car. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start.If the check engine light is coming ON.Then it will be more easy to get the fault detected.et the car scanned at autozone service center.Its free to get car scanned.As per the error code detected the faulty part can be easily identified and replaced.

Hi,

You'll need a scan tool that will read at the first thing I need to know is what is the injection control pressure while cranking the engine and also are the camshaft in crankshaft sensors in sync while you're cranking the engine. We may have a faulty sensor or possibly a faulty injector control pressure regulator. The two sensors will show yes or no war in sync. If they are not in sync then you'll need to replace usually the cam sensor. You'll want to order an ontogenesis scan tool this will take care of all of your needs.

Please get back to us if you have any further query or else accept the solution.

Thanks for contacting fixya.com

sounds like the computer is not working or is not making contact possibly bad ground if anyone has a scan tool and can read codes or if they plug it in and cant retrieve from computer, I would remove PCM and then try swapping with a known good PCM from another truck

check for tightness/worn out belt,or oil on pulley.

trucks have a limited slip rear end to help in turning. if both back tires are in the air they will turn,the drive shaft wont turn because its in park. to check the vibration you might check the balance of your tires

Hello there:
If you are positive that the fuel pump and the fuel filter(s) are clean . Over time deposits and tiny particles lodge themselves in the injectors. This can clog and injector and prevent it from delivering the fuel the engine needs. It can also cause an injector to stick open and send too much fuel into the engine. i would also recommend having the fuel line and the injectors professionaly cleaned.
and last Regular use of a good in-tank cleaner will keep you from having future problems with the fuel system

sound like bad blower motor relay.

Best thing to do is buy a repair manual for it at your local AP store and read up on the details.

Did you try pushing the volume button?

black mean runing rich unburn fuel

the pressure switch on the accumalator (big silver cold can)is bad, disconnect it and the compressor shoud turn off, if it does, replace the switch (2 wires)

Yes eather the vaccum line is loose, or the acutator is bad which will create a leak.

Ford has a 100k powertrain warranty on their diesels... You can get it fixed at Ford if it's part of the powertrain...sounds like it is...
with a simple deductible payment of 100 bucks... well worth it.

Need new valve seal.
