92 E34 starting problem
My 92 E34 with 166000 miles has been located in Denver CO for the last 2 years. On a recent morning, when the temperature was in the 20's during the night, I had difficulty starting it. Usually I turn the key, and it fires right up. On this morning I had to put my foot on the accelerator, and with applying different amounts of pressure, the auto finally started. Once it was started, the engine ran like normal.
A few days later, I encountered the same problem, but I was unable to get it started. With the amount of cranking I've tried, the battery is starting to get low. So before I try anything else, I'm needing to charge the battery. Any suggestions on determining what my original problem is?
