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 will go down this list tomorrow, a few of the checklist items that I've crossed off:

Electrical connectors are all secure and in order, according to wiring diagram.

Round Injector harness plug was never disconnected.

PCV hose secure to valve cover(non-original, generic hose, with very slight kink underneath manifold).

No intake boot removal.

Fuel hoses were removed- return hose is about 14" longer than hose to regulator(can't mess that up)

I installed chip according to specifications, however, I tried to start the car prior to chip install with no luck.  I figured, let me see if this idles, then install chip.

I checked wiring diagram before installing chip in ecu.

I will check the fuse and relay first thing in the morning, and disconnect the the positive terminal(only had negative disconnected due to very corroded 8mm @ positive terminal).  I didn't want to disconnect the positive terminal and have to replace that.

I will also remove ECM for verification, but again, issue was before ECM removal.

 

Thanks so much for the help, B C.  I am an Audi tech from BMW, Volvo and Porsche beginnings.  Glad to be here.  I may have one or two posts, from the before-time.  I am confident to get this car optimal, as I drove it in from Varun's place this morning, with no major issues (albeit a slightly lumpy idle).  It does need plugs, which I'll be sourcing from local auto parts stores(Bosch, or NGK, according to forum), and will update with results likely around noon.  I want to swap back in the stock injectors, and witness it fire up, after the other tests.
