I just put a new engine in my mazda protege 99 and I cannot get that car to turn over.
Can anyone offer any help? I have checked all electrical and fuel. Someone said I may need a new computer - any suggestions?

 

Did it turn over fine before you put the new engine in? Did you hook the starter connections up? Is your battery dead? Also, when you put the motor in, did you make sure nothing bound up with the transmission? When you turn the key, do you get a click, or anything? Does your guages and other electronics power up with the key on?

Need more information.
