On cold mornings my engine turns over fine but will not catch and run right away. Sometimes it turns over constantly until it attempts to catch and then slightly backfires. Then after a couple more tries it catches, sort of stalls and then runs normal all day but over night into the next morning if it is 50 degrees and above it starts and runs normal.
Need the year, make, model, miles and engine type of the car.
When was the last time you had a tune up done ?
When this happens have a can of spray starting fluid on hand, spray it into the engine air intake, if the engine starts you may have a failing electric fuel pump

electronics supply place sell a spray that cools to -60f.
there is a component or device overheating,and if you spray freeze spray on the suspected items,the stalling will go away until it heats up again.

Possible leaking injector(s), leaking head gasket so there is water in a cylinder overnight, or coolant temp sensor reading colder than actual temperature, which would induce a flooded condition. Narrowing down the possibilities can be accomplished by asking these questions: Does the coolant level stay the same, or has it gone down? Is the check engine light ever on? How many miles are on the fuel filter, spark plugs and other regular maintainance items? Fuel is in high demand on a cold start(filter). More fuel easily shorts out a bad spark plug. Too much fuel floods an engine and causes it to run rough or die if it even starts(coolant sensor/leaking injector). Feel free to contact me with more info. Thank You.

CTS are very sensitive to problems with the hose between the air filter box and the intake. If it is not on good or leaks, it will cause the car to run rough, or die immediately after starting.
SOURCE: drives fine and then won't start or stalls.
remove the cover from around the fuse box under the hood on the drivers side then try moving the wires around from the main fuse box where it runs down from the box to the top of the transmission, have somebody try to start the car while you are doing this and see if it starts up there is a splice that likes to get hot and quit working in the pink or red wire that powers a portion of the fuse box including the fuel pump fuse. look for a brown spot in the wire, if you can make it start by moving these wires around cut the brown spot out and re-splice them together using a **** connector. seen it a thousand times....

Hi there. Sounds like it could be fuel pressure. Did you try unscrewing the cap on the fuel rail to see if fuel sprays out or just drips? I'd check that first..
