-check starter connection if the nuts are tight and clean
-check the engine ground if its clean and properly tightened.
-perform voltage drop test good connection should have voltage drop of 0.2v or less.
-to perform voltage drop test first prepare the car to not start when cranking by removing fuel pump relay, use digital voltmeter put the red terminal on positive post of the battery and the black terminal to the starter thick cable which is called terminal 30 +then crank the engine result must be lower than 0.2v if not problem can be from connection points or the cable.
-same test perform with voltmeter to negative post of the battery and starter housing.perform the same procedure.

Hello,

Have you performed voltage drop test as mentioned above? High resistance cables can cause engine hard to start.
What type of engine oil are you using? High viscosity oil can cause the same problem.

Perform voltage drop test and please tell me the result, really interested to know what's the problem.

Good luck.

You are welcome.

Hello,

When your value is more than 0.2 volts then you have bad connection or bad cable.

Hello,

Make sure your battery is in good condition because most of the time battery can effect from cold weather.
If you can run an outside cable from battery positive post to starter terminal 30 which is the thick cable and recheck if it doesn't make any difference replace starter.

Hello,

Very nice to hear that, have fun then, congratulation.
