check for 12v key on power at ignition coil connector and the triggers for voltage when you crank. not sure if you want to do any electrical work.

update...

Well just got the ECU slaped it in and ...  Nothing new .

Still the same BS issue .. not only  its doesnt work but i cant even get the car  to  get fixed since it got broken into .

I just found discovered this  thing wich i have NO idea what it does  and well i though i would ask you guys . ill explain , u know how the Triangular looking connector that goes to The crank scensor.. well there is another one located below  and well i found the thing that was connected to is Broken and just tucked in behind the engine . now  if anyone knows what  i am talking about  can u please tell me what is that thing for ? and well i guess to get to it i will have to remove the whole air intake , injectors and throtle control and all that to find out and get to it .

heres a pic of the thing i found ..

does it plug into/connect to anything?  Is it connected/plugged in now?

If it is supposed to be plugged in, do so.  And make sure the connector pins are clean and fit correctly.

So i went to help Constantin today with the car thought it may be an issue with the alarm wiring. Yes the alarm wiring was a disaster it was disgusting. Anyways, we found out when he unplugs the cas plug behind the timing belt cover there is a weird sound inside the intake manifold and the stock mbc clicks. When we swapped the mbc it didn't click but didn't fix anything lol. So ya below is a picture of what he was trying to show. Its random 2 wires with a broken plug it looks like below the cas plug. Nothing looks out of ordinary around there. Im not Mr. Mechanic but i know that should go somewhere haha.

if ur talking of the ignition transtor john  .. we test all 3 of them on his car and all worked perfectly .. not so much on my car .. :(

im thinking of getting it towed to a shop and but it on a real computer and see whats up .. and maybe get it fixed  i am jsut tired of it !

still remains the question why does it fire only on  2   and not all four .. :(

That looks like the connector for the stock airbox vacuum. Which should be plugged in (wires), but plugged with a screw (hose)

Apparently he has changed the crank sensor.  His car is CAS less, unless I am confused, I do see a few engines every day  ;)

Cam sensor would be located on the transmission end of the engine, on the firewall side of the valve cover.  Hockey puck sized, metal case.  3 wires coming out of it.

Not on a 7 bolt. Already tried that one John. Unless he has a 6 bolt. I am sure he doesn't, he better not.
