I have a 1983 Volvo 240 that I got carbureted swapped. But I prefer EFI and will hopefully try to pass emissions with it. I had a 1986 740 GLE with the 2.2LH and after I crashed it I pulled the motor and harness from the car. Now that I have a 240 I want to convert it from carbureted to EFI but I need a little help understanding the system better, what parts are needed and how to wire its inorder to work. I do want to keep the points ignition system it currently has due to lack of money. Can anyone help with this conversion?
