my 92 7.3 idi has been hesitating at higher rpm’s and smoking a bit this morning I went to go do work with her and she bogged on me and started to smoke then shut off I managed to limp home is this a sighn my injection pump is on it’s last leg or is there something else I can look at I just changed the injection pump it was a used one but looked good and has been on truck working well until now

Lucio, you could have a bad pump but let’s eliminate the cheaper/easier things first.

1. Make sure you have more than a quarter tank of fuel in both tanks

2. Make sure you are getting fuel pressure at the filter head with no air intrusion. A clear hose and a pressure gauge will verify this for you. If you can run a long line to verify you have pressure while driving even better.

3. Make sure your air filter is clean and unrestricted.

change fuel filter first. then follow above suggestions.
it's going to get expensive real fast.
