95 riviera shift indicator

[Johnny114]

Well, it's been a while, I finally figured out my no injector pulse issue, the used ECM I purchased was probably N F G also, I found a company " Flagship 1 " that supplied a reman ECM, and she's finally roadworthy.
When I turn the key "on", the shift indicator flashes slowly 3 or 4 times, and is stuck in "D" , trans shifts fine, indicator does not change at all.
Anyone else have this issue ? Thanks again for all input getting this " 30 year old " back on the road again.
I have enclosed photo or two of the inside of the old ECM, comments are more than welcome!!

Flashing shift indicator might denote lack of communication. MIGHT be this,

Thanks for your response, When I bought the car, it would start fine in PARK, but not in NEUTRAL, so I did an adjustment to the neutral switch and got the car to start in park and neutral. I'll have to check to see if the reverse lights are functioning correctly.
Also when I replaced the ECM, I was instructed to use the PROM that came with the replacement ECM. I tried using the prom that came with the car in the replacement ECM, and the shift indicator worked fine, but the car would start and stall, my original issue, so I put the supplied prom back in, car will run ( not very good, but I could move it under it's own power, car doesn't have throttle response ), and the flashing shift indicator issue returned. I also got a " P0600 " code on my scan tool.
Being a Northeast transplant here to South Carolina, I am experiencing a different version of " Southern Hospitality " where people in the auto industry don't want to know y'all, but have earned the trust of my skills to a few other transplants and natives to the area, but for the most part, people do not return phone calls.
I have found out that I am a G D Yankee to them, making it tough to get some assistance, that's pretty much the reason why I am on this forum, thanks again for your suggestions

Yeah, I had a friend that lived in SC. Some of the people down there are still fighting the Civil War. It's also kind of like Mexico, everything is manana.

I am in NC and they do indeed love their Confederate stuff down here. Some things are different, life moves at a slower pace unless you are corporate.
