03 Buick century 3.1L I think.

New battery and tested it good.
When it does run good voltage from alternator 15ish.
Bridged the connection on the starter and it spins freely.


When it started getting cold like below 32 it would fail to turn the starter. Key in full power to everything but once turned to in gage the starter all power cuts out.

I'm thinking a sensor maybe? Any other suggestions please?

Thanks. I'm going to freeze my ass off around 2 PM checking them. I know they didn't look corroded but I'll start checking.

Funny thing tho was I would bring the new battery in the house to warm up then it would start no problem but last time I tried that I got nothing.

Couple times I messed with the power connection like loosened it a bit and it would crank. But again I'm getting nothing this time around.

STARTER SOLENOID BUICK CADILLAC CHEVROLET GMC PONTIAC

The power to most accessories cuts off when trying to start a car (normal). When the solenoid fails, the starter does nothing when the key is turned. On both my 3800's, the failure was intermittent. Car wouldn't start, turn the key again, started perfectly. Eventually it gave up completely. First time, I replace the complete starter for $150. Next time, I just replaced this. Local auto pats store did not carry just the solenoid. (Also check ebay)
