I'm working on a 89 ranger 4cyl 5 spd for a friend after another mechanic messed it up. I found out today that it had a computer from a 94 mazda in it. The problem is when it has the 94 mazda computer in it I can enter diagnostic mode and read codes and the fuel pump works like it should but when I put the old 89 ranger computer in it I cant flash codes and the check engine light stays on all the time also when the key is on the fuel pump runs all the time, to me it sounds like the computer. What does eveyone think?
