i had a obd1 ls motor i it and it was blown and we rewired it all and now i got obd0 ls in it and im not sure if the injectors or obd0. i just know that i can get it to start now but its throwing a code 4 (crank angle), and it wont rev past 3500rpm. it shoots fuel from the injectors i dont know if i need to get a new oring set for all of them or if i have to get new injectors?

 

The injectors are different, obd0 require a resistor box obd1 ( non h22) do not require a resistor box. What ecu you are running? Did you previous setup ( the obd1 ls) have a resistor box wired in? The injectors have nothing to do with the crank sensor code, it seems maybe a wire was crossed when you rewired the car for the new motor. When you had the obd1 motor in did you run a obd0 dizzy or rewire for the obd1 dizzy?
