alright new info...

code 8 is gone now.....we took the distributor cap off and the coil wire was all messed up....so we took my old distributor off the old engine and put it on and that worked so the TDC position code is gone...

the EACV code is still there though? we took the one off the old engine that was good and it still didnt go off.....we soaked one of them in carb cleaner to clean, still didnt work.......any ideas now?

also how do i set timing for the motor?

yes, the pm9 is if its for dpfi. that may be the source of the rest of your codes. the throttle position sensors wires are reversed on a dpfi so that may throw some things off, along with the extra 2 fuel injectors.

wow, that dizzy was toast. I suggest you open up the ecu by taking out those screws and seeing if it is in fact a PM9 ecu, not something else in a pm9 case. there should be another code near the harness plug ins on the inside, if it says pm9 in there as well get rid of it

turns out the ecu is a PG7 look on the inside:

PG7s work much better than PM6s on ZCs he should be good, unless the ECU is bad...
