Glad to hear the fluid starter trick worked, usually a good sign that everything else works.
For someone with no background, you did well on the light and resistance testing.

good to hear, can't wait to see some video of it running properly

I did some testing and came to a conclusion that made me feel so god damn stupid, but also made my day so great!
Started the morning with some starter fluid. It starts with starter fluid!!!

First I tested my injectors for resistance and they all came in at 14-15 OHMs. Good!

Then I made my self a geto noid light to check the injector harness for fire signals.

And it worked.

So then I was like "now why the hell wont my car start if everything is working electrically? Oh shit!!! My fuel lines are installed in revers." I had my return line and feed line mixed up the whole time! Dumb ass!
So now my car kind of starts. There is still something kind of funky going on but I get a rrrrrrrrrr gurgle and some smoke from it now which is a good step forwards. I am going to let the battery charge over night and then try again tomorrow.

What was going on with the no spark? You can always spray a little bit of engine fluid and see if it fires properly.

I was missing a few connections at the c101 plug that gave switched power to the coil and ECU. I am going to try some starter fluid today along with doing some more tests on the injectors.

hang in there buddy!

[deutschman]

I have everything but the injectors working. I am sooo close. Need a noid light. Ill be back soon.

[deutschman]

Injector firing but no spark = wet spark plug. If you crank and pull them out you should smell the fuel

Thanks.

I may be wrong, but actually everything is self contained within the distributor. Check that you have 12 v there, then a test light to see it flash every time a coil is suppose to fire. From there you either have a flashing light or none, or maybe even not 12v at the distributor.
Could be just a bad coil if you get power but no spark.

Ps that's why the distributor is aligned in the cam, as the cam dictates when it should fire. In newer cars they have a cam angle sensor that the ecu reads and fire the spark. No such thing in older cars with the big distributors

I am still having a hard time getting spark. The fact that I have a very limited understanding of how an ecu works and exactly what it does, mixed with the fact that the e30 engine harness is being mixed with a Painless wiring harness has me walking in circles right now.
I got a pin out chart of the ECU, so tomorrow I am going to start at the ECU and work my way forwards. First I just want to make sure the ECU is getting the correct ground and power. Ones I know that Ill work up to the wires that go from the ECU to the coil and see what kind of power they are putting out. Then coil resistance test, spark plug wire test, and points test. Man what a head ache.
I am asuming that the ECU dictates when the coil fires. Is this right? So if the ECU were bad the coil might not get power.
Does the coil get its power strait from the ECU? I think there is a yellow/black wire that goes from the starter solenoid to the coil. Man this shit rubs me the wrong way. So much to keep track of.
I know I have fuel at the rail. How does one check if the injectors are firing?

[deutschman]

Good to know. Ill have to check for 12v at the coil.

I took them off of my spark plugs because the wires wouldn't fit and it sparks fine.

Cool build dude!

Is that a NRG hub you have used for the steering wheel or is that a different brand? Im looking to get the same wheel for my mk2 golf but cant seem to find an nrg hub for the mk2 so was wondering if a momo one will fit the wheel.

Thanks

Its a MOMO hub. It fits great!

Thanks to everyone ells who has commented.

Got the motor to crank today! Now why dont I have any spark?

So the plugs I got from Blunttech had the wrong sized nipples that did not fit in the spark plug wires. Right now I am running the spark plugs with out any of those metal nipples on them at all. Could that cause them to not spark?
