Default Installed 450's with new head, car turns over but wont start.

d16y7 block
d16z6 head
d16y8 intake mani

spark plugs are wet so i believe the dsm 450's are working, wired in a 10 watt 10 ohmn resister (5 pack for 99cents at radio shack). i dont believe im getting any spark... pulled wire, plugged in a plug and grounded it. It made no spark. i believe my wiring is correct but it may not be. The y8 manifold doesnt have as many plugs as my harness which is a 95 cx, wired in with vtec. distributor, plugs, wires all good. ... could the 450's have messed up the ecu?...

did you rechip the ecu or did you think the ecu would magicaly compensate for injectors that spray twice as much fuel as the ones is programed for?

ok say the ecu is chipped, why not just grab a resistor box at the JY instead of hacking ---- up with 99c ---- from radio shaq
