    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.

    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.

    Sure thing, check your PM for my phone number.
    my checklist in some kind of order of easiest to hardest:
    -press down on fuel injector electrical “rail” to make sure all connections are secure. If any preload exists in the plastic “rail” it may not snap down on all injectors or may pop up
    - if the round injector harness connector under the manifold was disconnected (centered below the throttle body near the block) check that it was re-connected
    - usually the pcv hose that runs from the throttle body to the valve cover needs to be removed to pull the fuel rail, ensure that is secured and not cracked/leaking
    - if the intake boot was removed to gain access to the injector harness plug, ensure the intake boot is on and the throttle position sensor connector on the underside of the throttle body is connected.
    - disconnect the positive terminal on the battery and touch it to ground to drain the capacitors, then reconnect to reset the ecu  to allow new fuel trims to be established with the new injectors
    -pull the fuel pump fuse/relay (either or). Listen for the injectors to fire by feel/sound to ensure they are all firing
    -if fuel hoses were removed for removal of fuel rail, remove hoses and verify feed and return lines were not switched
    -check to ensure the chip was installed i  the correct orientation. If instructions came with the chip it would likely emphasize the correct chip orientation. The EPROM and socket have a corresponding notch on one end that are supposed to match up.
    if its installed backwards, bad news, the chip is toast.
