Engine is starting hard?

There are a few things that get affected by low temperatures.
First, the battery will not have as many, "Cold Cranking Amps", (CCA), at 30 degrees than it does at 40 degrees. Most batteries give the CCA at a certain temperature for testing purposes to see if the battery is working properly. If your battery is getting near the end of its service life, you might want to take it to a parts store or repair shop and have it tested.
The thickness of oil and how it flows near freezing is also a factor. Using a weight that is above what the manufacturer recommends will lead to hard starting and engine damage as the tolerances are tight in most new engines and weights like 20W50 are seldom used. This is because moving heavy oil around in an engine takes away power and increases fuel consumption. A lot of new cars use 0W5 weight oil with very small and tight bearing tolerances. This means less oil and thin oil, so it allows for less parasitic drag on the motor.
You can get an electric battery blanket and oil heater if you live in a cold climate. They usually have a short electrical cord to make hooking up when parked at home easy.
I hope this information helps.

You are welcome. If you ever need anything else I will be here.

You may have a weak fuel pump or a clogged filter/fuel line.

I would check fuel pressure and operation of the fuel pump.

Scan for codes and check fuel pressure first. Fp should be 60-66 psi so it may be a regulator it should also hold that pressure for 5 minutes after turning key off

Do what I suggested first

Hi Mike
First of all I need you to tell me a few things. When you say electrics went out, do you mean the dash went dark or the vehicle went totally dead? Also, your initial complaint was about a cold starting problem and your text indicates a concern over the electrical system in general. Could you be more specific about the starting trouble and are you sure it's only when the vehicle is "cold"? That will help in trying to determine your problem.

Have you checked fuel pressure? If so, whats your reading

Turn on the key and listen for the fuel pump. It should come on for 2 seconds or so then shut off. If you don't hear it check the relay. Also check the relay connector real close. As the pumps get older they can start drawing more current. That causes problems with the relay socket and the relay itself.
