Posted in electronics and did get much response. I swapped my 350 tpi out of my 85 to my 84. Problem now is the injectors are not firing. We have tested and all injectors are getting power and the wires go back to the correct pin on ECM. One thing i have missing is the VSS Buffer and Intake air temp sensor... these wouldnt cause my issues would they? I am thinking the ECM is malfunctioning. Any help is appreciated.

 

I need to replace my ECM but i can not find the service numbers this is all i can find.

 

you problem is not the ecm. you mite have a security problem my car is doing the same thing. and you mit need the ecm that come with the tpi unit at least the prom that the only thing that can give youa fit and you can order a new ecm from oreillys or autozone all you need is the number and the dc code and the year and model of your car that it come out of i bought one it only costed me 65 bucket new
