Default car doesnt start

i put in the newer long nose crank 1.6 ,hooked up my turbo and the other stuff.used the new motor coilpack but used the old coilpack harness because the new ones sensor was cracked.im not getting spark from the pack.the car cranks .does anyone have a diagram or picture of the bottom side of a coil pack to see if i wired it right.also the plug the pack plugs into in the main harness makes my test light go on when its cranked.also can the cas sensor through off the pack.

You've got two trigger posts and two 12v+ posts. I'm not aware of any sensors on the coil pack, so I'm assuming you meant connector.
Here's a photo of the coil pack bottom. The 12v+ is the big post- the lead with the black heat shrink that covers the terminal and the other is the trigger.
Here's diagram of my DIS2 wiring for reference.

Look at the post size- the big ones are 12v+ the small ones are trigger. You can't put the small nuts on the big posts. hth

Start with the basics. Is the connection to the CAS and AFM good? If you junt TEN and GND will it start?

Since it's torn apart - hook a meter (or test light) to ground and your trigger (plug wires removed) and crank. That'll tell you if you've got a signal coming to the coil from the ecu. If you do, and there's 12v to power post, then it's the coil, wires or plugs. If you don't work backwards from there. That would include the CAS and ignitor circuits. Could be something simple that you forgot to reconnect?

I have a garage and when it's pouring out and I'm working on the car my legs and feet get wet.

A more simple approach might be to return your original items to the install. If it doesn't work then it's most likely something you've done (or haven't done) during your install. Take my word- electrical problems are usually stupid simple.

im done,just have to fine tune it.i thought i mesed up on the wiring of the injectors and ressistors but i didnt.
so i took off the fuel rail and noticed fuel was at the top of the injectors but wouldnt flow..then swap in the unmodid injector harnes and 1.6 injectors and the same thing happend it wouldnt flow.then remebered that my friend connected the lines.switched them up and it started right up.then put in the 440s and it statred right up.
