Hi all it’s been awhile. I believe I have a remand bad pump on a new engine installation. Got it from QS tuning. Installed the remand pump hard starting, missing, smoke and cylinder balance codes on all 8 cylinders.

put my original pump back on and it took care of the problems and no codes.

Both pump installations timing was set within specifications and did nothing different to the engine between pump installations.
The bad thing I bough the remand pump last year and QS tuning said they could check it $500 but it is technically out of warranty. He did say after they check it he might be able to work w/ me. In the mean time I found this bulletin go to the last page sec 5 engine diagnosis. What are you guy’s opinions on this?
thanks guys.
