    OK, what did I screw up..

    Pretty sweet first post. Here we go:

    Bought the car a couple weeks ago. The service indicator light on the cluster was tapped over. PO said the the PO before him had tapped it over since he didn't know how to reset it.

    Well yesterday I decided to get the tape off and reset the indicator as per some instructions I found.

    Heres where I fucked up. I mistook the (I'm assuming the C101 plug) that runs along the firewall for the diagnostic plug located beside the dip stick.
    Found that information a little to late...

    From what I can tell I connected pin 13 and pin 10 together on the C101 plug, and then pin 5 and pin 7 in another attempt to reset the light.

    As far as I know:

    Pin 5 = Oil Pressure
    Pin 7 = Terminal 15 is not secured
    Pin 10 = Oil level dynamically
    Pin 13 = Electric Fuel Pump

    I then realized I was at the incorrect plug. Found the diagnostic plug and successfully rested the service indicator. Got everything back together and now the car won't start..

    Did I fry something in the ECU?

    This is on a 1990 325iS

        Check the glovebox for exploded ecu.

          Removed ECU and opened it up. Nothing looked "exploded"

            would it start before you reset the SI lights?

              Yes it started before I set out to try and reset the service indicator.

                check your main relay and FP relay.

                        Yes it turns over. Makes no attempt to catch or starting firing though.

                          check for spark when cranking first, or if anything, just swap a readily avail ecu.

                          it is rather simple to

                              Are the injectors opening? Check by putting a screwdriver on them while cranking. Put your ear up to the end of the screwdriver and you'll hear them clicking if they are opening. If you hear nothing, then the ecu is not telling them to open, or there is an open in the wiring from the ecu to the injectors.
