Ford Super Duty (1999-2016) :: GPR Does Not Trip When Key Is Turned Over
Apr 1, 2013
My 7.3L GPR does not trip when the key is turned over. I have the 12v constant and never get anything out of the two smaller wires. I can lay a screwdriver over a small pole and the 12V constant and I get the 12v on ther other larger pole, and around 8v on the smaller poles. My wait to start light does come on and stays on for a short period of time. I have ohmed out the glow plug relays and the injectors.
Here are my numbers passenger side (front to rear)-----0.6, 0.5, 3.8, 3.4, 3.4, 4.0, 0.5, 0.8
and the driver side was (front to rear)-----1.0, 1.0, 3.7, 3.4, 3.4, 3.4, 1.0, 1.0...
My questions would be is there a problem with my PCM or is it just more likely the wire from the GPR to the under hood connector at PCM. If so where can I find a wireing layout to test that. One last thing with my truck is that it has an after market alarm with keyless start that no longer works and is just in valet mode. Not familiar with the way these alarms are wired do they cut into the wire that turns on the GPR. Could this just be my whole issue?

I just bought an 04 F350 with the 6.0 diesel. I have the trip computer but it doesn't seem to be working, the screen is just off. Tried the buttons, nothing. Checked the manual, can't find anything. Is there a trick I'm missing? Or is mine broken?

So the other day i opened the door and heard a super loud clunk noise come from the door and when I turned the car on and pulled hte window down it wouldn't go down all the way, only about 75% of the way so I assumed like BMW cars the window motor died but oddly it continued to go up and down just now 100% down.
Then 3 days later when I came to drive the car again the window went down to the 75% mark and now its jammed there with no movement even if I tried to lift the window up myself. Usually a broken motor allows this to happen but since it isn't budging I am wondering if its an electrical issue with the power window button more than the motor?
I say this because when i try to lower the passenger window from the driver side it works than out of no where on the 3rd time it wont move at all than 5 minutes later it will move or if it doesn't move I just go and pull the window down from the passenger side then I come to the driver side and try it and it works again than it'll stop again. So maybe its the power window control buttons on the drivers side that's failing?

I have a 2001 F250 V10 5-speed that I've had for about 3 years with 60,000 miles on it that I drive about once a week. About 4 months ago I stopped at a convenience store for 3 minutes and when I came out truck wouldn't start. Turned over strong had fuel rail pressure but wouldn't start. Had it towed home and was going to investigate the next day but the problem was gone.
2 months ago I stopped to get gas and went into the store and came back out and everything was dead-no audible with key and door open, not instrument cluster lights....as if it didn't even have a battery in it. I pulled the negative cable from the battery for a couple of minutes and put it back on and it started back working. It worked until 2 days ago and had the same problem with everything electrical being dead and removing and replacing the negative cable brought it back to life as before.

I just bought an 09 f-250 lariat 6.4 . It has 100k on it. Was driving it AC was working fine. Next time I got in it went to turn the AC Auto on and nothing..the display works fine..lights work..looks like it is working, but nothing. No fan no anything.
Also, the check engine light will come on too. Then next day everything works fine again. Check engine light is out..everything looks perfect. Then this morning the same thing happened..check engine light and no AC.

I just bought the truck and the ac was working and now out of nowhere when you turn it on it just blows hot air so I just assumed it was out of free on so I bought an ac pro but that did nothing.

2012 F450 Dually King Ranch 4x4 - I have read many threads on front end noise. I started hearing a noise when I turned left or right and then slowly run over a speed bump. I listen to music at an average sound and I picked up on the front end noise. For some reason you can hear it in the driver seat better.
Anyway I took the vehicle in and the mechanic said he didn't hear anything. I thought, he forget his hearing aid today? I have this expensive warranty plan that would actually cover a few items in the front end but Ford is claiming they don't hear anything.
In their defense I have figured it out why. When the temps are below 40 the noise gets louder and I think by the time they looked at it (8 hours after I brought it in, 5:00pm) the day was warmer.

When I turned it on for a second, last winter, I rem hearing a clunk, and then another clunk when I turned it off. Made sense to me.. So, I figured I'd just activate it again now, and roll up and down the driveway once to exercise it. BUT, when I turned it on this time, the light came on, but no clunk when it came on, or off. I went up and down the driveway anyway, and I THINK it felt like it was ON, but I didn't make any turns, because I figured that would be bad.
Any one that is silent when it locks? I think I saw a post where everyone said it's supposed to clunk on/off. Could it just be the season/temps, only clunks in winter? I have a 4x2 btw, so it's just a turn switch. I hope it's not stuck or frozen somehow already..

Truck wont start with key. It has a brand new battery, brand new starter & brand new solenoid. When I turn the key to the on position the lights come on but it wont start. The truck will start when I jump the solenoid. Im wondering if its the ignition key cylinder or the ignition switch, or maybe something else like a relay or faulty wire. Where I should start or what the problem could possible be?

My '04 f250 with a 6.8 V10 will periodically stop like you shut off the key. It will restart immediately, but you have to shut off the key first. Associated with this are all sorts of codes that appear to be spurious like something is glitching the computer. When it started we were moving out of state so I took it to my mechanic. They chased the codes and found nothing out of whack.
Codes cleared and the next time it happened new ones appeared. The last time it did it the transmission temp gauge quit working, but comes and goes when I drive it. I also have a problem with the key fob needing to be reprogrammed when it happens and the codes showing it is in learning mode like it had been reset or the battery disconnected I am pretty sure it is a wiring problem or maybe the ECU power relay is bouncing.

I had just installed an amplifier and speakers into my f350. Everything looked fine in the wiring, but when I turned the key on, I heard a sizzle. Now the truck won't start, although the battery is charged and all the lights come on. It does click, so the ignition relay should be working. Where to start looking for the problem? I am going to disconnect all wiring related to the amp and stereo for starters as well as try the reset mentioned in another thread tonight. If that doesn't work, what's next?

When my hvac controls are turned to hot, I'm getting only luke warm air. When moved over to cold it feels like the a/c is on...granted it is 21 degrees here. What I've done so far:
1. Flushed the coolant system at the local COOP TBA
2. Flushed heater core-Both heater hoses are hot to the touch as well as the heater core itself. The hoses are within 10 degrees of each other tested by an infrared temp gauge.
3. Verified the blend door actuator is moving. I can see it spin while attached to the box as well as I pulled it out and plugged it in it will move from hot to cold.
4. Smacked the #$%! out of the blend door box.
The fan still functions as it should from low to high. The truck also gets up to operating temp as usual.
Is it possible the actuator is still faulty even though it moves and not going all the way to the heat side? I considered picking up a replacement but I hate to start throwing parts at it.
Did the blend door give up? The snow is here and I need the heat for those 4am waterfowl hunting trips.

My 2002 Super Duty blower makes a gargling sound when I turn it past the lowest level. Why?

Ok here goes I dive a 1999 f250 super duty with 5.4 it's automatic 4x4. I dropped my kids off at school and was headed home turned a corner when the oil/temperature light flashed and the truck just quit. I tried restarting it and it just clicked like the battery dead. Had my better half come and jump it. Did not work it would only roll about a half Revolution and stop. So we towed it home where I put the battery on the charger. Now I can't even get it to roll over. And yes there is oil and it did not over heat.

The whole trip over here weren't any problems. Yesterday I went to the store, started fine. When I walked out of the store, the truck turned over 3 times and just stopped. After that all I got was a click at the relay on the pass fender. I have good batteries. I have verified current through the fender relay down to the starter but I cant get it to turn over. Another thing to note is the solenoid got so hot it burned me.
This, I have never run into. I replaced it today with a new starter with no luck. Could I have a bad, "new" starter? What would cause the solenoid to generate so much heat just sitting there? The longer it stayed connected, the hotter it got.

I recently purchased a 2000 f250 with a 7.3. I'm new to diesel motors and new to super dutys so
Problem; had been driving for an hr and truck, which was running fine shut off like someone turned the fuel off. Check engine light came on, motor cranked but wouldn't start Back up. After an hr or so it fired back up and ran fine. This happened several times until now it will not start on it's own. I use a quick shot of starting fluid it fires right up and runs fine. Have run the truck for 1/2hr or so driving it and no issues except check engine light staying on. Shut it off and it will not start again without starting fluid, which I've only used 2x and sparingly. Generic code reader says no codes.
Is it vapor lock? Under valve cover plugs connection?

Every time I put the headlights on or just the running lights within 15 minutes it trips the tire low pressure warning, how can the 2 be connected? Turn the light switch off and anywhere from 5 to 20 minutes the warning low pressure light turns off. I know take it to Ford but I'm out of State presently and l'll just wait till I get back home next month.

Here in the last week or so I have noticed what seems like loss of power in my 04 F250. When I get on the gas it doesn't seems to respond like it used to. When I turn off the truck i can smell diesel a little bit. could it just be a clogged injector, bad plugs or what?

2007 ford f250 .... 200k on it ....
Just had refurb engine installed with new oil elements as well. On a 9 hr road trip, the wrench light came on but no other warning lights.
No stock gauges showed any raises in levels.
No noticed loss of power at all.
The light would only come on once I drove at about 75 mph for about 10+ miles. It would not turn off when i slowed down, but when I would kill the truck and restart it, the light would be off. Just driving in town or on the highway briefly, nothing comes on. Took it in to oreillys to get scanned and they tell me a few codes pull up but none of them are valid. What would trigger the wrench?

I have a 2014 f250 with the my ford touch radio. In February I had to have the audio control module replaced because it was shorting out internally. Since then I've had a crackling noise in my speakers when the radio is turned up over half way. I'm about to drop it off at the dealer for the 3rd time and I'm going crazy!
