7.3L powerstroke

Hi all I really need some help. We have a 1997 f250 that was running fine I mean like just bought it brand new fine and then while going to town, check engine light goes on then right off (never came back on) and loses all power and still has no power. Found that the injector sensor on left side was bad, replaced still nothing. When you can get her to crank she idles perfect, very little white smoke. When you try to drive her she doesn't want to go over 40 mph. Any help or advice would be great. Thank you

Sorry, also. Shes getting fuel. We checked the bowl and the overflow both are fine. It's like she's getting too much or maybe not enough air.

What do you mean by "injector sensor"? No such thing on our trucks.

Have you scanned for codes, either before or after replacing the sensor (whatever it was)?

Just as a fyi those are not sensors on the gasket but where the wiring passes through the gaskets to run the glow plugs and injectors.

It sounds like your exhaust back pressure valve is stuck closed. It is usually used to aid in cold warm ups. It is located on the exhaust sided of the turbo. You can unplug the electrical connector going to it which is almost under the turbo or you can disconnect the activation rod and wire it into the open position. The truck will run just fine without it connected.

What are the actual codes?

(Also, it would be good to get the codes again after disconnecting the EBPV.)

Did you try disconnecting the back pressure valve or did you just unplug the electrical connection?

If you just unplugged it you might try disconnecting it and wiring it where it is always open.

Also on the exhaust back pressure sensor here are some instruction on cleaning it

Other than that you might need to find someone that has a scanner that can read live data to see what is going on.

Thank you all for your help. I tried the sensor and read the codes still says exhaust back pressure. I think it's time we find her a home with someone that can afford her. I just did nit want to give up on her yet. I did find that I have a non ebpv pedestal. So apparently this has happened before to previous owner. Again thank you all for your help and sorry if I wasted anyone's time.
