Thanks everyone for all the help. Sorry for taking so long to respond but I have been dealing with a lot of stuff going on lately and haven’t been able to get to posting.
I solved the problem though, it was a completely dead “Coolant Temp Sensor” tested it for resistance and nothing. so dropped a new one in and started up fine and runs alright,
Thanks Again,
JeremyOkay so I have been looking up different things and I’ve got an idea on why the “ESC code” is popping up. My thought is that computer is trying to advance timing more because it is quite a bit colder out now.
when I rebuilt the engine I put in a (Elgin Pro Stock E-923-P “Camshaft Specs“) camshaft, and the timing was set around 20+ Degrees Adv. when running and it ran fine, well when I got it started today the codes were still there and the engine was pinging.
I don’t have access to a degree wheel so i set timing chain dot to dot, during engine build. Any in-site on my current theory would be great. I’m also thinking this could be causing the MAP sensor problem as well because vacuum in the intake is incorrect from bad timing.
Sorry for the long post. I could be way off base here with my theory here I’ll be the first to admit I’m no professional Mechanic lol B)
oh I did go back through again and checked every connection and they are all good, even the ECM.

Thanks College Man, I’m going back out to start checking everything over again. being a 89 do you mean the ECM instead of PCM? also if all connections are fine what sensor would you recommend to start maybe replacing.
