Nice, I was thinking about going for the same setup with the x brace, strut bar, and jack pad cover.
Thank you,
Fixed

Nice to see you join us!

to note: i bought injectors from ebay and received a set with multiple DOA injectors.
also to note: if the car ran before you worked on it, than didnt run after, SOMETHING YOU DID changed the running state, so dont bother looking elsewhere. there are coincidences, but very very rarely.
So, I double checked that I had the ECU chip in correctly. That was good. I went ahead and swapped back stock injectors and it fired right up. I left my volt meter at work along with electrical test tools, but I am positive something is wrong with these injectors. They definitely look like the Bosch injectors and have the same PN as the popular 19lb injectors for E30s, 0 280 155 710. Also have a Ford logo on them.
She runs now, I have a few more little things to wrap up in this car and Varun told me I could take it on a short drive, I'll be begrudgingly giving it back to him today, as this is such a beautiful vehicle and drives so nicely. Thanks again to B C for the checklist, as I triple checked my work, as any decent technician is going to think "what did I do wrong, what did I do that could cause this", a bad technician will blame the parts immediately.

PS HEY PATRICK LONG TIME NO SEE

I am using similar injectors in my M50. Mine also have Bosch and Ford logos because they were OE on a Ford Contour SVT with a 2.5 V6. They were the closest to matching flow to stock M50 injectors while having a better spray pattern. Good news is they are likely not Chinese clones, but they are used and must have a problem. I don't recall how the fuel rail setup on an M20 is but on an M50 I needed to machine spacer rings or there is a possibility that they could drop into the intake manifold far enough that the top comes out of the fuel rail. Pics here. Maybe yours have enough material on the top for the retaining clips?

Ordered some E30 M20 specific ones from a known BMW injector seller. Lets see if round 2 goes better.

Jack Pad Cover? @GunMetalGrey

Quick update.
Returned the injectors that didnt seem to work and bought a similar set from Bimmer Baron. Car fired right up after installing the new injectors on both the stock and tuned ECU. According to @jcw0101 there is a noticeable difference in power delivery and I cant wait to take it for a spin this weekend.
Thanks for everyone who helped troubleshoot and provided advice. @B C, @straight6pwr, @jcw0101

Finally had a chance to drive and take care of some minor maintenance items.
Tune: Wow, its freaking amazing. I wish I had done this 2.5 years ago when I bought the car. The tune/injector combination provide increased power throughout the rev range but especially below 4K. Its better everywhere without adding any harshness or reducing daily drivability. (cant say the same for the M5 tune)
Battery replaced: Finally I dont have to jump the car every time!
Coolant Reservoir: 32 years is old enough for that plastic.

were you in MKE this weekend? thought I maybe saw your car!

What was the tune/injector combo you went with on this?
*Saw the BimmerBaron eBay link for the injectors, was any modification needed to fit those injectors?
What was the chip you ended up going with? Still this one you had linked previously?
I'd like to something of this nature that is relatively cost effective and easy to install for some better throttle response and feel.

Injectors: https://www.ebay.com/str/bimmerbaron - 19lb for M20.
Tune: http://www3.sympatico.ca/mdsylva/products.htm . I would contact BimmerBaron regarding the tune since he sells or can direct you to a low cost tune. I dont know which tune it copies though.
Installation: Dont need any other parts assuming you already have the 173 ECU which I believe is a requirement for the tune. I didn't do the actual install but @jcw0101 essentially used this method: https://www.youtube.com/watch?v=EKpRvIwXzT8. Pulled the valve covers instead of the intake off. Overall its pretty simple assuming you have the right parts.
