Throwing p1300,1305,1310, & 1315, what will cause this?

Question

I just pulled the engine recently to replace, head, clutch, front and rear main seals, etc. Put it back in and hooked everything up. Started up the engine and it was running perfect. Cut it off and on with no problems, then all of a sudden it shut off and now is not getting fire to any cylinder. Please help.

Answer 1

This code when it comes to 1300 check the ground connection, improper ground for the this code if not the ground connection it the ECM. if this was caused by a poor ground and the ECM is replaced you will end up replacing the ECM again.
