cold weather start problems

[PlanZero]

Simply put, the colder it is the harder it starts after sitting overnight or after work. Above freezing she starts fine, but when its twenty degrees out it takes a few tries; below zero it takes fifteen tries. It will occasionally start for a second then die. I've replaced the cts, the battery and plugs. Wtf? Any suggestions?

Store in a garage if possible, if not maybe invest in a block heater, should cure most ailments.

Not possible. Gotta park on the street. Anyway I went to auto zone today and I still have a cel for the coolant temp sensor. I don't understand. I replaced the cts, the cts connector, the thermostat and radiator months ago, and I thought the ecu would reset when I put a new battery in. Most likely, the cts is still the culprit, I assume? Any thoughts before I order another sensor and change that PITA in this weather?

What about relays in the fuse panel by the ecu? Should be a relay for the cts. That could be your problem

What is the car doing. Is it having a hard timing turning over? Is it cranking continuously but just not starting?

Are you running any tuning software? How are the plugs looking? Sounds like it might be getting too much fuel.

Haha I fixed the problem. It was the ect sensor connector. I had to cut the wires back to the harness and replace the connector. A $20 fix. Also replaced the plugs. No cel now either.
