THIS^^ Get rid of your (pointless in my opinion) exhintake mod, put stock gears and stock cams in, time it to the FSM and try to start the car.

EDIT. Hold on a second...how are you running Exhintake on a 99 head? Are you sure your cam is out of a solid lifter (99-00) motor? You can only run the earlier cam if you convert to Hydrolic.

Also, i cant remember if its possible, but check your CAS to make sure its not 180 degrees out... would be a basic thing to do and i dont have one anymore to see if you can even do that.

well the CAS wont be, but the spark outputs could.

typically when you crank, and it's about to catch the motor stops itself, like crank crank clunk, crank crank crank clunk.

With what you say... assuming the wiring is adequate and properly connected you have improper timing on something... be it injectors, spark or cam

Cam timing would be more obvious and was detailed earlier in this thread... but if you still have the stock intake cam... its worth a shot (at this point)
The pins are 14 gauge pins (same as 14 gauge wire which is adequate). I have double checked most every electrical connection for sensors and such. Only thing I can't remember checking is the cas which I will check again.

I am in georgia now, flying home tomorrow afternoon, limerock all day saturday to watch, and sunday ill be at my parents house, monday I fly back to georgia. So no promises.

Are you SURE those are the injectors you think they are and not like 550s or something?
I am sure, got em off JayL (https://www.miataturbo.net/miata-parts-sale-trade-5/injector-dynamics-1000cc-fuel-injectors-53161/)

It is a 99 cam I got off a member on here. I verified the cam # with the exhaust cam that is already in the head. If I can't get her to go I will eventually give up and put the stock intake cam in.

I verified the COP wiring to be correct (from the ECU to the cops). Is there any other way they could be wrong?

Holycontrolledexplosionsmotherfucker!


Starter fluid in the egr port of the manifold for ~2 seconds and it tried to stay running. When I hooked the fuel pump up it wouldn't so I am guessing too much fuel for initial start. There was a backfire in there somewhere but at least I know now it is still a fueling problem and I can stop ******* with other things.

One more data point: when I tried using starter fluid in conjunction with the fuel pump the car would only crank like it had been doing before but once I disconnect the fuel pump it'll sputter and try to stay running.

No way man. I had no fuel pressure and I am pretty sure the timing was off (both the intake cam and tdc)

Yeah, if only I had time to actually work on this tune thing. Been busy with photoshoots, which isn't a bad thing, so I have merely glanced at it a couple times over the past few days.

Hopefully by the end of this week I'll have enough time to figure out how to tune and actually do it.

and good job on finally using some starter fluid, now you know what to look at.

Yeah, I figured that no fuel pressure was a problem so I wanted to fix that before I resorted to starter fluid. When I had fuel pressure and it still didn't work I decided it was time to spray it.

I know it only takes a few seconds to cut the pw down but I'd like to find the correct injector opening time and calculate the pw's.
