1985 toyota sr5 pickup, 22re engine will not turn over when cold out

[WRI]

My 1985 toyota sr5, 22re engine will not crank/turn over when it is cold temps outside (usually below 32 degrees F). It only makes a slight buzzing noise coming from the location where the ECU is at when you turn the key to start. In warmer temps outside the truck cranks right away with no issues. Anyone else have this issue?

I am gonna guess maybe your battery is too weak to turn it over in the cold. Whats the cold cranking amps for the battery?

Also this would probably fit better in classic section.

Thanks for the reply. New to site. The current battery in it is 930 cca, but this problem has been going on with other batteries I've had in it. I had this battery tested and was told it was fine.

After further troubleshooting from switch & harness to starter it seems to be in the solenoid.

Turned out to be worn contacts.
