Hey guys I sold my 89 dx hatch to a buddy that i did an MPFI swap to about a year or so ago with a SOHC ZC ran great!, no he's decided to put a DOHC ZC in it and we cant get any spark from it dont know why it ran when it was pulled from the other car it was in. I retraced all the wiring and everything checks out ok, its not throwin any codes and im getting injection pulse but no spark if anyone has any ideas please let me know thanks in advance!

 

check the ground on the thermostat housing....and make sure you wired up the cam angle sensor correctly...the sensor mounted on the end of the exhaust cam...take the 2 blue wires from the dizzy and run them to the wires on the cam sensor....could also be the dizzy

 

all the grounds are good and the wires to the cam sensor are hooked up correctly but still no spark but it did run before!

 

try and switch the two white wires on the dizzy i had the same problem till i met a guy that had a zc and said to do so and it fired right up..... good luck with that man

 

$5 says its the ignitor in the dizzy.
They're notoriously crap in the DOHC D16A8/A9/ZC's

 

word...you prolly got a dizzy issue man...those things can be working fine one minute and literally 10 seconds later the igniter will go bad....your best bet would be to find a known good dizzy and swap it in to see if it runs...a brand new one is gonna run you no less than $230

 

Yeah, what distributor are you using? It should be a TD-03U (88-89 Integra). And yes, they are notorious for having igniters crap out, especially if it's one that came with the swap.
