Could be the fuel side. Change the fuel injector.

First do you hear it trying to work, is it like a "clack, clack, clack" sound? or you hear the motor running smoothly? You will need to remove the door panel and take a look behind the plastic water seal to see whats going on, it is either going to be the regulator ( part the motor is attached to...cable broke)/damaged or more likely the nylon bushings inside the motor itself, they run like 10 bucks on Amazon. If you take the motor out of the regulator assembly be careful not to let the cable system come apart/unwind( use nylon ties while motor is out to hold in place). The motor itself is straight forward open/replace worn/falling apart nylon bushings/relube/reassemble. The tricky part is not screwing up the regulator assembly...depends on your skills.

You have to remove the face of the radio to get to the bulbs,

I suggest to check fuses and reset security switch; if this dont work, could be the fuel pump issue.

Hi,This POST describes the P1450 - Evap and fuel tank related.P0133 is: Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)Your 02 sensor is likely worn out. Your Merc is 13 years old and is likely due. You do NOT have to buy from the dealer, as they can be bought online for much less, if you can replace it yourself. Usually just a wrench and connector needs unplugged, but depends on where they are located on the exhaust.Td
