Just as the title says car won’t turn over in the cold but runs really strong and starts fine when it’s warm. Stuck seafoam in it to try and clean it out to no avail, help.

change the the fuel pump relay… i bet that is your issue…
its starting when the oil pressure comes up enough to close the switch in the oil pressure switch… nothing to do with the gauge sender but in the same part…
remove the fuel pump relay cover. i bet the contacts are burned away…
this is the exact problem you describe…
i have found several 98 Chevy trucks with blocks of sponge in the underhood fuse block holding the fuel pump relay in place…
So it was def a problem cause the first time I tried to start it after replacing that relay at about the same temperature, it tried to start but sputtered out and it did it like 10 times before it actually turned over, but before it wouldn’t try to sputter at all until like the 5 try. I’m thinking plugs at this point
how is the ignition coil looking on the outside…
external dust circles indicate external high voltage leaks…
you can use a spark plug… with some wire wrapped around the hex and connected to a good ground to unplug the coil wire from the cap and see if you are getting a bright blue snappy spark…
if you only get an dim orange spark. replace the coil…
on the fuel pump relay… did you check the insertion and extraction force of the relay in the underhood fuse block…
Ignition coil passes the eye test, I don’t have time to pull a spark plug atm and I was letting it run for a little while to charge up the battery after the 30 attempted starts and yes the pins have good retention
I talked to the previous owner and plugs were done a couple months ago I guess
