Q: Engine sometimes cranks, sometimes doesn't. Battery is fine.

asked by on

Once after I jiggled the shifter from side to side with car in park it started. I don't know if this was concidental. I suspect battery cables are corroded or that there's a loose wire in the starter circuit. I am not very car savvy as far as cleaning battery terminals, checking voltages, etc. I will see my mechanic tomorrow.

My car has 101000 miles.

Hello. There are a variety of reasons for why the car may not start. This may very well be a loose wire or bad grounding to the battery or potentially even a bad starter relay (this is usually noticed by the car making a clicking sound when you turn the key). I would recommend checking to be sure the battery cables are clean and the connections are good to start with. If this does not solve your issue, have this checked by the professional in order to diagnose the starting problem and assist with repair.

Q: My car stalled, I checked the oil and it was low. I added 2 quarts and barely made it 4 blocks. There is no pressure when pressing the gas.

This may or may not be related to the low oil level. If the car was overheated and potentially has developed a blown head gasket, this may be possibly what have caused the stall. When this happens, the cylinder head...
