So i bought a 2000 motor that had an auto behind it and put it in a older truck with a stick behind it
so if you rev above (guessing no tach) 1300 RPM the throttle goes no more you push to the floor and it just stays the same RPM.....
I dont have the OBD II port so i took to cummins and they told me
ECM idle switch low voltage something or another indicating the TPS being bad and charged me 100 bucks
so I changed the TPS with a good one I had and same issue
another shop told me that being the ECM and motor was once pared with an auto tranny and needed to see the trans to work and this has a manual?
any one have any ideas this motor is 100% complete stock besides the way I tapped the harness as seen below
Plug with white lever:
VP44 relay control_________brown/white tracer_____________relay post 86
VP44 power______________Red/green tracer______________ relay post 87
ECM power______________Large red/white tracer___________Constant hot
Key on ECM______________light green/black tracer_________ignition wire key hot
Black plug
ECM and sensor grounds________Black/ brown tracer________GROUND
it starts and idles fine and it just wont rev past that RPM
