New here but have had 6.5s for a while now. I've done research but am at loss.

I have a 1995 k1500 6.5
Situation started With erattic idle and then hard start when hot. So I just replaced my 5288 injection pump with a reman 5521 from Pensacola fuel injection. After purging air I finally got the truck to start and idle . The problem now is I have throttle response when in park or neutral but once in any gear there is absolutely zero throttle response. From what I have researched I should have no issue with my current prom (BXRD 1624 4850) when switching my 5288 pump to the reman 5521. Is this correct?

The codes pulled are as follows

DTC 35 - Injection Pulse Width Error (Time Short) -PMD or Injection Pump fault
DTC 19 - Crankshaft Position Reference Error


I will add that I have a brand new pmd from Leroy diesel with a 9 resistor

Any help would be appreciated
Thank you
don’t know if you solved your issue or not but I have had this issue twice in recent years. Both times it was the jumper harness going to the sensor

Are you talking the optical sensor or the cps?
The optical sensor. (The jumper wire with the noise reducer in it) 1 end plugs into the engine harness and the other end plugs into the optical sensor. Take that section out and plug the engine harness directly into the optical sensor. Both times I had this issue I had the same codes and the same problems

Thanks for the tip I will try that tomorrow and see what happens. I was curious as to what that little jumper was for
It’s a “noise” reducer supposedly made to reduce electronic interference between the IP and the computer. I have driven over a 100,000 miles without it and never had a issue

No I do not. I did a little bit of research about one but haven't gotten that far yet
i have a tech 2 now but 1 of my old laptops has the gmtd software. If you need it I can send it to you. You would just have to buy the usb to obd1 cable
