BMW 318i wont start engine

sounds like a engine sensor i'd guess at the crank sensor but to be sure you would need to get the OBD codes read , this will give the exact fault so wont waste money trying sensor(s) on a hit an miss basis,you can buy a code reader online not expensive just make sure it covers your vehicle make then you have a valuable diag equipment for future use

Check engine light? If not try changing the transmission filter.

i see dash lights on when you try start engine.could have faulty starter relay or bad starter solenoid or starter bad.use a 12 volts test light see if power going to starter.if starter circuit okay could have theft security problems because BMWS did have theft security key ignition system back in 1994.

the plug into the pump cud be corroded--pull and clean--chec fuses--pump may need replacin--must hav about 35psi--

could be a problem with the security chip in the key.

If its a regular rubber hose then you should not have to remove the engine they are tight but can be done without removing the engine

should but you will likely have to change the tracking

check the brake-light switch itself.

sounds like crank sensor

You need to check the blower motor in car ...

Good luck..
