BMW 118I N46B20BY HSA NO PULSE IVE CHANGED CRANK SENSOR BUT STILL NO PULSE

SOURCE: i have a 1993 bmw

Hi the crank shaft sensor is located just above the front pulley at the front of the engine and is held in place be a 5mm hex bolt, undo this and remove the sensor then you will need to follow the wire that dissapears under the intake manifold and unplug the multiplug, replacement is the reverse, regards mark

SOURCE: no spark no FI pulse NO START

Check the ignition switch please. Had that on a 93 Ford that it was bad and the coil wasnt getting any electricity while the switch was in "start" position.

SOURCE: no start. i have gas, spark and injector pulse

yes it would due to timing if the sensors are bad the engine want start due to timing 

SOURCE: my car has fire to the plugs and i have change

any fault codes stored for the security system?is it an oval key or kinda square?the sqaurish looking one would have a transmitter rot the anti theft system and cause the incident you describe if there is a malfunction.observe the security lamp on dash while trying to start engine.if it stays on solid this is most likeky the area of your problem.

SOURCE: 1998 grand maquis crank no start no injector pulse as well as no ignition spark. Have changed crank sensor, cam sensor, fuel pump, pcm, injectors and still no start no voltage to sensors or injectors

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.
