Yes did that as well still no codes . How ever I did more probing around and found out that it does have spark . The first time we checked to see if it had fire was buy sticking a screwdriver in the plug boot . Probably not the right way but when we was on the side of the highway we didn’t have much choice lol . So last night I was in my shop and had some old plugs stuck them in and sure enough I got spark !! Now I can spray some carb cleaner in the throttle bodies and it will run .
