So I just installed a greddy kit on my 90 1.6... went to start it and it sounds like no spark.. I can smell fuel, so that leads me to spark as well... I haven't pulled the plug wires to see if they arc yet though..

Here's the other reason why I think spark... the other night I was a dumb ***.. working on the car while pissed off, I tapped into the ignitor signal (wht/ylw) on the ecu for the o2 clamp and wideband instead of the +12v(wht/red).. could I have fried my ecu or ignitor? Or am I overlooking something stupid?

mr.na

start by removing the plugs and check if they spark... Is there any friend close to you who has a 1.6l miata?? You could swap ignitors/ecu to troubleshoot. If the injectors are pulsing, you ecu is functional. Double check your wiring or soldering job you've done on your ECU wiring...

Work with your head cooled down, you'll be more focused at your tasks. Like racing, anger will send you into the wall or grass...

Yeah I'm getting a spare ignitor and ecu from a buddy tomorrow night but I was hoping to have it running today..

My ecu wiring is good now. It was just me not paying attention and grabbing the wrong wire to splice like an idiot. I should have realized it when it was smaller gauge than what I was expecting for a power wire, but too late now.

The check engine light comes on w key on, so I know ecu has power..

Damn, well good luck man! Electric issues are horrible..

Yeah it just frustrates me. Electrical is my specialty.. I've built full engine harnesses from scratch and had zero issues first time, people come to me for their wiring.. I go to hook up simple power and ground in my own car and screw it up lol

One of my buddies didn't clip in the ecu plug all the way in after days of torture.. It's just one of those things.

Never mind. Apparently it was just grumpy. Checked spark had spark put it back feathered the gas while cranking and she runs.

God I missed boost..
