Hey, new here and having trouble with a truck a work. Its a 1995 F250 7.3L Powerstroke. It has been sitting for 3 years after a rat had chewed through some wires. I have repaired all the wires, put new fuel in, and changed the filter. It starts up, but idles real rough and when I press the throttle slowly it doesn't respond, if I slam it down it revs, but once it is floored, nothing. To get it to do anything, you have to pump it rapidly, and it is not a fun ride. I switched out the TPS with my boss's 1996 F250 7.3L Powerstroke, and it is still acting the same. I am at a total loss and any help would be appreciated.
Stuck/bad IPR or ICP? bad PCM/IDM perhaps? Being that you are actually getting some kind of a response out of the engine id lean towards the IPR sticking or ICP not responding correctly, but it couldn't hurt just to verify the modules with ones out of a known working truck... just remember to use YOUR modules in the other truck to verify just in case, that way you dont end up having to fix 2 vehicles if something in your truck messes up their modules
^^^^^^ +1; you can do this with the key on, engine off. Set the scanner to read pedal position as a percent, and slowly press the pedal. The percentage should go up gradually and smoothly and not jump around.
Had to get a scanner. Got the Actron Elite AutoScanner CP9185. But I cant get it to read the codes. The truck is OBD1, and I found the connection under the hood. it will run the test, then say connection error after it has gone through it all. Will do it with both KOEO and KOER fast and slow tests. Been trying for several hours. It will connect to the truck. Don't know if its because I only have 1 battery on the truck right now or what.
Ok, got it to pull KOEO codes. Got the following 2 codes.
4095 Manufacturer Specific Code
013 Manufacturer Specific Code
But I dont know if these are right because the truck is a 1995, the transition year between OBD1 and OBD2, and when I put in 1995 as the year the scanner has it set as OBD2. So I have to set the year to 1994, which was half 7.3 IDI. So dont know if that is screwing things up.
