I purchased my Friends 86 a couple of years ago and it was in storage for a few years before that but I knew it worked fine and had zero issues the last time it was out and he took it to Laguna Seca and a Local AutoX.
Engine Rebuilt in 2010 with all OEM Parts.
4AGE 16/20 with about 6K miles on rebuild.
During this stay at home mandate, I have been working on it and noticed a few issues that I would like to remedy.
upon cold start, it has to turn over for about 5 seconds before it starts but once it starts it ides fine, and when at operating temp you can start it back up with one turn but if left for over 4 hours it'll take a couple of quick turns to start up again.
The other issue I'm having is that it loses power or feels like a fuel cut after 6k-6.5k and will not rev higher.
On that note, if I do some light-spirited driving and take a turn(even a 10 mph turn) it will stay on but lose power for 2 seconds then act normal again.
I can drive the vehicle all day for whatever distance and it'll be fine as long as I'm not Max Maxin it everywhere!

Can't Hear the fuel pump prime when in the ON position but once started car idles and runs good until you try to go above 6K.
Diagnostic FP jumped to B+ kicks activates the pump when in the ON position.
I'm leaning toward a Fuel Pump prime issue for my cold starts but what about my 6k Rev Limit?
They have to somehow be related and that's where I am asking for some help..
I'm going to check the Fuel Dampner and if that's good I guess I will focus on inadequate fuel pressure from the pump to the injectors.
Any Tips or Tricks?
Thanks for reading my story!
