The check list I always use:
pull codes
check TFI pins 3&4 run & start signal in the right place
PCV has metered air
Fuel Pressure 28 psi Idle, no vacuum on regulator 35 plus
timing start at 8-10 BTC
triple check firing order ( this is not a chevy its done different)
plug gaps .45-.50
no fancy spark plugs use cheap ones
thermostat 190-195 make sure its not in backwards
Baro/Map sensor mass air should not have a vacuum line connect to it. ( baro sensor)
O2 sensors are left and right make sure they are.
grounds, should have a common ground for the EFI no sheet metal screws in multiple places.
vacuum leak, might need to get a smoke machine, google how to make unless you have access to one they are expensive.
get a EEC-IV breakout box and verify all signals go where they need to go, 2 people can do this in 30 minutes.
and if you have a bunch of brand name parts with lots of fancy names and big number you may just put together a bastard system that will never run. I like factory parts once a shake down run has been done fell free to experiment.
