Top 20 2001 Ford F250 Super Duty Super Cab Questions & Answers

the speedo is activated by the VSS in the transmission check wires and that unit

oil in a radiator indicates that the transmission oil cooler in the radiator tank has failed and leaking transmission oil into the radiator there are 2 possible fixes fix one is a new radiator fix 2 is to give the radiator oil cooler a miss altogether and opt foe an air cooler mounted in front of the radiator the advantages here are that the radiator then has a bigger capacity to handle the engine heat as there is no hot transmission oil adding to the engine heat the second advantage is that the transmission oil is being cooled to ambient temp and not engine temp which makes for longer transmission oil life the disadvantage is that it cost a bit more than a radiator initially but the long term savings are real oil to air oil coolers are available from auto transmission shops and quality auto spares shops

Check the ground on the connector on your van is the problem

Front CV joint noise.

faulty starter relay in the engine bay. should click when you turn key but if its melted into place it will keep the engine running.

Check fir worn cv axles some times when off the gas will makes noise as will bad wheel bearings both easy to check... But possibly based on miles uout transfer case may be worn or need service.. Front end work can often rid if these odd noises.. 2001 not that old would chrck for codes see if input, output sensors on trans ot transfer case needs service.. Many time can take sensor out remove metal shavings as the sensor most of the time is manget as things wear dowm sensors sometimes dont respond as they should.. But take look at axles if there play due to age the may hum whem coasting... Check blog got common problems to your vehicle they all seem to have samr general problems with age.. From make to model see what others but be careful with YouTube has more not too do s

i got new pcm to ???? Was it programmed ? Dealer ! checked senors 5 an 7 are the ones that ive found to be the promblem ?????????? What are sensors 5 & 7 ? 2000 PCED On Board Diagnostics II SECTION 5: Pinpoint Tests Procedure revision date: 01/07/2003 A: No Start A: Introduction A1 CHECK PASSIVE ANTI-THEFT SYSTEM (SECURILOCK)

WARNING: BEFORE SERVICING OR REPLACING ANY COMPONENTS IN THE FUEL SYSTEM, REDUCE THE POSSIBILITY OF INJURY OR FIRE BY FOLLOWING DIRECTIONS IN PINPOINT TEST HC WARNING, CAUTION, AND HANDLING.
• Release the fuel pressure.
• Install fuel pressure tester.
• Scan Tool connected.
• Key on, engine off.
• Enter Output Test Mode (refer to Section 2 ) and run the fuel pump to obtain maximum fuel pressure.
Is fuel pressure at the specified pressure (use the fuel pressure chart in Pinpoint Test HC)? Yes No GO to A8 . KEY OFF. GO to HC1 . A8 CHECK FUEL PRESSURE LEAKDOWN
• GO to Pinpoint Test HC and observe WARNING, CAUTION AND HANDLING.
• Fuel pressure tester installed.
• Scan Tool connected.
• Key on, engine off.
• Access Output Test Mode and run fuel pump to obtain maximum fuel pressure.
• Exit Output Test Mode.
• Verify fuel pressure remains within 34 kPa (5 psi) of the maximum pressure for 1 minute after turning pump off.
Does fuel pressure remain within 34 kPa (5 psi)? Yes No KEY OFF. GO to A9 . KEY OFF. GO to HC1 . A9 CHECK FUEL INJECTORS FOR VPWR
Note: Check at least two fuel injectors, one on each bank. A no start condition can exist only if greater than 50% of the fuel injectors are without VPWR.
• Disconnect any two fuel injectors.
• Key on.
• Measure VPWR circuit voltage at fuel injector harness connector.
Is voltage greater than 10.5 volts? Yes No Natural Gas Vehicles: GO to A15 . KEY OFF. GO to A10 . REPAIR VPWR circuit. A10 CHECK FUEL INJECTORS ABILITY TO DELIVER FUEL
• Connect fuel pressure gauge to Schrader valve.
• Cycle key several times.
• Locate and disconnect the inertia fuel shutoff (IFS) switch.
• Monitor pressure gauge while cranking the engine for at least five seconds.
Is there a pressure drop greater than 34 kPa (5 psi) while cranking the engine? Yes No The electronic engine control system is not the cause of the no start. RETURN to Section 3 , Symptom Chart for further diagnosis. REPLACE PCM (refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) ).

make sure the cables are both good if they have a spot that feels flimsy the wires inside are likely corroded and the current is not running through it properly. a simple charging system check would be recommended.

Here is a link to a 2005 Gas 5.4. IT should be exact or very similar. http://www.ford-trucks.com/forums/905288-no-start-issue-2005-f250-5-4l-2.html

Check the chain in the transfer case.

To do this you are most likely going to have to remove the head liner from inside the cab.

You can remove the lens and the housing, but you will have a large hole that will need body work and a rood repaint. Best to keep them. Here is a good installation link that shows the holes: http://www.powerstroke.org/forum/99-03-7-3l-exterior-discussion/181253-cab-light-install-pics.html

Many possibilities. Check for vacuum leaks, weak spark, bad tune up items.

forget the torch idea as it will damage the axle bearings appear hard but in fact cut readily with an angle grinder cut at an angle and almost all the way in get a cold chisel and hit the cut hard and the bearing will crack and be easy to pull off

Remove the door panel. Screws can be at the door handle, in the arm rest and at the bottom. First lift up on the panel and pull off. If it doesn't lift up, then pry the panel off. Plugs hold it on. Remove the noise barrier, if it's there. Have the window up. Remove the bolt for the window guide at the bottom. Pull it down a bit, not out. There are three plastic clips to unlatch that holds the rods for the door handles At the door jam there are three torx screws to remove. Pull the latch out some and remove the plugs.

It's inside the fuel tank. You have to drop the tank to access it.

If power at fuse, must have power coming out of fuse. Check both sides of the fuse. If no power to switch that's all it could be if the plug is all the way on the switch and switch is good.

run the fault codes and check for TCM problem. If it shifts into neutral like you describe then the engine would increase in rpms as the load came off. More than likely shifting into a too high gear which indicates a selector program problem.
