Buy a new crank sensor from a Mitsubishi dealer. For that sensor always buy OEM parts. More expensive, but 100% reliable.

Any codes? Maybe another sensor has gone bad? MAF?

Do you have a warning light on? If so get the trouble codes read.

it is illegal in europe/japan for these foglights to work on anything BUT low beam.as the light spread from these would be defeated if main beam were on in foggy situations.in other words pointless having them switched on.you could always fit accesory spots/driving lights.(like rally cars)but these MUST only come on with high beam.(so you dont blind oncoming traffic.)

When you changed the battery the computer must re-learn the setting again. If it continues have a OBD II reader plugged in and check for codes.

check for vacuum leaks in failing hoses and loose fittings

- bad connection(s) on starter relay, or
- low charge on battery, and
- and maybe some others... but these are most likely

I have a 95 Eclipse and I recently had to change out my TCU........ Transmission Control Unit, This should be located directly beneath the center console. First I would have the transmission services if problem persist then proceed to changing out the TCU you can get off of ebay. As far as i know there should be 3 Computers in our cars. 1 the Electronic Control Unit located behind radio 2 Transmission Control Unit located under center console and 3 Airbag Control Unit located under hood, Hope this helps.

well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem
