My 1995 Volvo 940 wagon won't start right up in cold weather (below freezing).
You stated that it was hard to start. Did it crank over more slowly than usual? If so the motor oil may be too thick for below zero temperatures. If it cranked normally, there are a number of things that can cause this.This car has fuel injection controlled by the computer(ECM). If the temperature sensor for the ECM is out of specifications, then the ECM will not fuel the motor properly when cold starting. Old age, lots of miles can lower compression and cause hard starting. the fuel injectors may be worn, defective or clogged, delivering the fuel pooly. Was there a check engine light on? This is before mandated ECM monitoring, but if there is a light on, there is a way to check what it is causing it. There are other things like cracked vacuum hoses that can affect the starting. Worn spark plugs and wires can have an effect. When it chugged coughed and spit, was there black or blue smoke coming out of the tailpipe? Black smoke is too much fuel and blue smoke is oil consumption. I know that it is hard to decide where to go for repair, but the dealer has trained personnel, and a warranty for repairs. In my experiance as a dealership technician and an independant shop owner that some things are better off at the dealer, unless the independant shop has factory trained people and lots of information available, you may be charged with them trying to learn on your car. I had a 1987 LeSabre that when the temp was way low, the coil pack failed to spark the car.
