Question about 2002 Ford F250 Super Duty SuperCab

1 Answer

Intermittent A/C operation

I have a 2001 Ford F-250 Power stroke and the Ac system is acting up. It will run good for a few hours then for no apparent reason the a/c clutch will stop and it will blow warm air into the cab. If I increase the rpms it will usually start back up. We went to our local Ford dealership this morning and they did a service of the system and added an extra pound of refrigerant but apparently did not find or correct the problem. Any suggestions

I think your a/c clutch is going. If it works for a while and cuts out, the electrci clutch is getting hot and losing the ability to stay clamped.
Sometimes, you can shim the clutch so it's less of a gap to close. Or, replace the clutch.

2001 F250 Diesel getting air in the fuel lines after being shut off for a few hours.


I would think the only way air could get in the fuel line after sitting would be a drain back condition. Check all fuel lines for a "crack" some where along the system. Not big enough to leak fuel out, but to suck air in.

Why my 97' f-250 7.3 powerr stroke keeps dieing while idling


The power stroke engine has several things that will cause this problem #1 crank shaft sensor AKA cam shaft sensor on crank shaft located on passenger side of engine near crank shaft pulley # 2 IPC sensor Injection pressure control if has oil in sensor replace it & wiring pigtail .#3 high pressure oil pump not up to par. #4 injection pressure regulator solenoid they get sticky. with a good scanner that has FORD enhanced software you can check all of these without leaving the drivers seat and perform running tests on injectors and test the ficm module interface with the pcm. Fuel Injection Control Module & Power Control Module.

My problem is, I have a 1987 f250 ford 6.9 desiel. It starts up and runs for about 10 secounds,then acts like its starving for fuel and dies out.


Truthfully it sounds like a bad fuel pump,or relay, or low voltage at the pump (all could cuse tis. Without more specific info about your engine it's hard to say, but you can try this first.
Get anew fuel filter and fill it to the brim with ATF and refit. Do not open any drains. Start the engine and let it run for about 30secs and shut it off. Leave the truck for about 3 hours or preferably over night. Then start it and drive it and see if there is any improvement.
Also you may want to post this on the pre-power stroke page in the diesel section. A lot of smart guys there (just go down the main forum page a bit). Hope it helps.


The idea of the ATF is to clean any gum or similar from the injector pump.
Pull the filter again and empty it. Fill it to the brim with ATF and refit. Do not open any drains. Start the engine and let it run for about 30secs and shut it off. Leave the truck for about 3 hours or preferably over night. Then start it and drive it and see if there is any improvement.
If this helps you resolve your problem, please
consider giving a good rating and a quick thanks
or good job.It will help me as well Thank you

the power steering pump also is connected to the brake booster and both take vaccum this is a verry common problem and sucks, the only way to fix this is to get a new power steering pump, just to have it happen again in a few years.

2004 Excursion/Powerstroke/ On Warm days, ac loses power. I turn the key on and there is no lights on the AC. Then, it comes back on and works again. Sometimes after couple of hours. I am assuming there is...


Could be the relay, the controller, the temperature sensor in the coolant system, the compressor, the R-134 level in the system, etc. What is SOUNDS like is that you may have a bad ignition switch or trouble with your harness. At any rate, the intermittent nature of it (I'm assuming that when you say "it comes back on and works again" that it works normally during those times) suggests a likely electrical issue.

1988 Ford F 250 5.8L EFI wont start


Since you are getting spark and fuel we know you are good there. Check the timing on the engine. Turn the engine from the front of the crankshaft with a socket and a large breaker bar until you reach top dead center of the intake stroke. Then remove the distributor cap and check to make sure the rotor is pointing to the # 1 cylinder. It almost sounds from your description of the sound the engine is making that the timing chain has jumped a few teeth on the gear. These factory gears have a nylon coating on the teeth and over time the nylon chips off the gear. When to much of this plastic gets chipped off the teeth it results in chain slack on the push side of the gear. When you shut the engine off it can jump a few teeth at the very last second before the engine stops rotating the crank and cause it to jump teeth. The engine probably has high mileage and might need the timing gears and chain replaced now. If you perform the visual check with the distributor I think you will find the chain has jumped a few teeth. If you need more help come back to this site and one of us will be glad to help. Good luck. Let me know what you discover.

7.3 power stroke acts like it running out of fuel


have you had it on a scan toll? did throw a code? it sounds like your sucking air into the system through a rubber boot from the aftercooler. as far as throttle response have you had the injectors checked?
