hey guys first post, ive got an sl500 91 model, the problem is that the car is not starting. What i think is the prblem is the central locking is not working properly and so the engine immobilizer is being activated, causing the car not to start.
The fob does not activate the lights on the doors, hjowever the key itself lights up. Using the key unlocks and locks all doors and the compressor at the bakck is working
When i turn the key, 4 lights on the dash flash for abotu 2 seconds and then stop, they are; the seatbelt, low petrol,engine oil and one other one

What could be the problem, the car cranks but does not start
thanks guys
