Starting Issues
So I am having issues with my 93 SC400 where during the warmer weather days the car starts with moderate hesitation and on the colder days it almost never wants to start. I’ve seen people saying it’s an issue with the ECM but I’m not sure how to go about addressing the issue. The car has 205k miles on it with new plugs coil packs and a new crank sensor and it still won’t start on colder days

So I got the car started on a colder day and the check engine light came on after a while and it’s idling a little rough and Jerks when I floor it like it’s not wanting to take the power I’m throwing at it and after the motor is warm it starts up with no issues
might help to tell us what the check engine light said...? not going to lie its probably the ECU if youve done coils wires plugs. Could be like an Idle air control solenoid or something but your giving us nothing to work with. we are not magical...

so I have reset the codes after running. It some when it was warmer out. And codes 12 52 and 55 are the only ones that remain. I’ve tested that the power is going to the coil packs and it is but it’s not always firing from the packs which confuses me. Any ideas?
