20 Most Recent 1993 BMW 5 Series Questions & Answers


IF the solenoid which activates the starter is not working, you would not be able to get the car to start with jumper cables (bump ?)
So the problem could still be starter related.
There are a lot of questions on FixYa about 'theft/immobilisers' and not a lot of answers.
I hope yours is starter related.

Suspect your crank sensor signal may be weak. Here are some tests you can run with an ohmmeter:


CYLINDER IDENTIFYING SENDER

Testing
M20, M30, S14 & S38 ENGINES
See Figure 9:

Fig. Fig. 9: Cylinder identifying and engine speed sensor pinouts
The cylinder identifying sender is mounted on the ignition lead for cylinder 6 on the M20, M30 and S38 engines. The sender on the S14 engine is mounted in the bellhousing flange and connects to a gray colored plug mounted in the center of a group of 3 plugs on the engine compartment rear wall, next to the engine harness connector and diagnosis socket.
Turn the ignition switch to the OFF position.Trace the sensor lead back to the connector and disconnect. The S38 engine might require the fan and shroud be removed and the water pipe be moved out of the way to access the plug.Check the resistance between terminals 1 and 2. The resistance should be 0.2-1.0 ohms. M42 & M50 ENGINES

Fig. 10: The upper connector is for the cylinder identifying sender and the lower is for the speed sensor (DME)-M42 engine shown, M50 has similar arrangement
The cylinder identifying sender, or camshaft sender as it is sometimes called, is located on the timing cover. The connector is located below the intake manifold, towards the front of the engine.
Turn the ignition switch to the OFF position.Trace the sensor lead back to the connector and disconnect.Check the resistance between terminals 1 and 2. The resistance should be 1.15-1.41 kilo-ohms.


ENGINE SPEED SENSOR Testing
See Figures 9 and 10
The engine speed sensor provides the DME unit with engine speed information. The sensor reads the information from a tooth wheel mounted on the crankshaft hub except on the S14 engine. It can also be called the crankshaft sensor.
The S14 engines speed sensor is mounted next to the cylinder identifying sensor and is removed in the same manner as the cylinder identifying sensor. The sensor on the S14 engine connects to a plug mounted in a group of 3 plugs on the engine compartment rear wall, next to the engine harness connector and diagnosis socket. It is the connector on the right side.
Turn the ignition switch to the OFF position.Trace the sensor lead back to the connector and disconnect.Check the resistance between terminals 1 and 2. The resistance should be 490-590 ohms.

SCanned the compter to know what fault codee is stored there; with this code number could send you other details; sometimes Autoxzone or Autoshop with scanner reader make this job for free.

Keep us updated.

twist out. Righty tightey Lefty loosey. Don't touch the replacement filament, the grease on your fingers will cause it to blow.

It means that you need to plug in a scanner and read the code and see what is making the computer unhappy. Lots of auto parts stores will scan the codes for free.
The two most common problems that set error codes are loose gas caps and worn out oxygen sensors, but there are dozens of possible causes.
