Three separate systems tha wok together but need diagnose seperate Like anything start battery and ends 1st thing because no battery Have to stop Ok then ck starter and if ok ck alt voltage then next juice at the coil juice at the plugs and then Gas and so on and so on until you figure out what's up codes are nice obd1 people don't use much anymore I do Obd2 tells you what to replace most of time. Obd1 makes you look for problem you have to figure it out.most dealers now won't work on obd1 cars.what does that say for the industry .bo hiss and they want to fix my car .110 hr I don't think so.not unless shop formans around .most shops Have one diagnosis guy and parts changer.i love to figure it out.sometimes I dream about car problems and,most of the time,I fix them in my sleep I'm nuts I think but I love cars
