02 4runner ecm..vsc trac

Hey yall I bought a used 02 4runner for a good price because they said bad ecu. When I got the truck the cel was on and the VSC TRAC and TRAC off lights were both on. It would start with gas pedal help but pedal would go to the floor and no acceleration much at all. I took original ecm part number 89666-35590 out and bought a ecm from online part number 89666-35591 which was supposed to be plug and play. Yes I ordered the right one but they sent me the part ending in 1 and said it would work. Well now it only cranks and will not fire. What yall think ecm needs to be programmed to this VIN? Thanks for all the help

 

Does it start with the previous ECM? Sounds like the new ECM isn't right.

 

Sorry. Yes it started and would run but had no acceleration until the gas pedal was almost to the floor

 

I mean, have you tried to switch back to the previous ECM?
