While I have never experienced your problem so, I won't be of any help to you but, since you said the check engine light came on you need to get the codes read they will help point you in the right direction. Just so, you know auto part stores cannot read the codes on these trucks it needs to be a powerstroke capable scanner i.e. dealer or a reputable shop or you can buy an ELM 327 bluetooth adapter $30-50 and then download the Forscan app not the free version buy the upgraded version it's like $3.99-4.99. Good Luck!

I have a friend that runs a shop who doesn’t mind me coming down to use his scanner. I decided not to work on it today one because of rain and two my carpel tunnel is flared up I cant even hold my wrench. I’ll run the scans then the fuel tests to check the fuel pump and filters. the rpms do rev up when parked and also when trying to drive but the truck just wont go over 5 mph.

First, I am very sorry, be as patient as you can, it’s extremely hard, I’ve been down that road. Lost my Father this past December, He (We / myself as his only family member capable) battled with his Dimensia for several years.

Second, I guess I’m coming to the party late- went back a reviewed your posts. Noticed you got a CEL, are you able to pull any codes?
It’s hard to be patient because he calls me every couple hours asking for an update and I tell him the same thing over and over, I’ve even tried writing it down for him to read and he still does what he wantsi got him his Nissan back Tuesday (had to get the. Catalytic converter changed out) so he’s off my ass for the moment.
He was fine till my mom passes January 2nd 2019, then last February he needed to replace the rotor on his truck I got it for him and but he bugged me everyday that he needed it. Then when I gave it to him his truck sat with the tire off, new rotor on the drivers seat till last month! I tried to put it on for him several times last year and he would get mad and say he’s getting to it. Now it’s to the point if something goes wrong its my fault. 2 weeks ago when all this started, he backed into my fence pulled Forward put it in reverse again and gunnedd. It right over my fence into the ditch when I got into the truck I noticed the brake light on, pop the hood fine the serpentine belt wrapped around the fan and no cap on the brake fluid. THen after replacing the cap and the belt I found the drive belt tensioner cracked in half so that started my journey into the truck. I also found that his brake fluid was spraying out at the caliper maybe just hand tightened! But ask him Someone stole the cap and I loosened the brake line. anyways thank you for the fuel suggestions I’ll keep y’all update, I appreciate all suggestions because like I said definitely NOT a mechanic! just someone who can fix what’s broke if I have to. Maybe to cheap maybe learned a little watching my dad work when I was a child.

Have you been able to verify fuel delivery from your tank(s) to your fuel bowl? Take a look at the below, attached post paying attention to the #4 thread and the description of running the fuel pump inlet to a separate can of diesel fuel. While the truck will be stationary, at least you can see if the engine responds to the throttle and increases the rpm without stumbling. Hope this helps. Glenn

It can't be on the throttle body because there is no throttle body on a 7.3L diesel. It's on the pedal assembly.

well changed out the pedal assembly and it ran right for a few min then it sputtered and the check engine light can on again i tried to drive it but it just crept up and down the road, the odometer also didn’t register either, my father was a diesel mechanic before he lost his mind to dementia, I’m a waitress with a business degree not a mechanic, why he thinks it’s my job to fix this truck is beyond me. Any ideas on why it’s not getting up and going.it starts right up just no go!!

Where is the throttle position sensor located on the 97 f250hd 7.3l powerstroke on the pedal is the idle and accelerator pedal sensors I’ve already replaced this whole pedal but I can’t find the TPS, I thought it is on the throttle body but my dads POS truck is giving me so many problems and I’m tired of throw parts at it!!! Any diagram or picture of the vicinity where it may be found??? help

Blondbimbet, do you have a question on this? I'm fairly certain the Dorman TPS is still available, but I haven't looked lately. This thread is 11 years old. Cheers!

I can't seem to find where the tps is located on the 97 f250hd 7.3 powerstroke I may be confused but I'm pretty sure on my dads pedal is the accelerator pedal sensor and the idle sensor ive ordered that but I was reading and watching utube and almost everyone keeps calling the parts the wrong name and when I ordered the Tps
