I have rheingold and a USB-ODBII cable, but can't do any programming, or re-coding.

Can someone who actually has done it please tell me what I need, be it ICOM, or whatever? I think I have a problem with my DME/EWS, no start condition, but power is fine, ignition backprobe shows power to the Starter, so I am now stumped.

I have replaced the MAF, the fuel pump, and TB, it ran fine for a test, then I tucked the DME and relays back into the box, and now - nada. Will not turn over.
