Ignition problem I have a 2000 328i, Manual, accidentally left the lights on the other day, and my engine would not turn.. lights turn on radio works fine but nothing coming from the engine... It feels like turning the key without holding down the clutch... no turning, no clicking, nothing... sounds easy enough, i took the battery (deka) in to be recharged... hooked it up... and found my self in the same place.... I tried to jump start it yesterday with no luck... everything works just no turning from the engine... I need help i have a feeling its something easy... i have never had any starter problems this is the first time this happened... I checked the voltage on the battery and it appears to be fine.  I do not know where to start... Ignition Key? Neutral safety switch? starter?

There are fuses and relays everywhere. You need an auto electrician.

it's a manual means my transmission is manual transmission?
with a left foot clutch ,the clutch switch is bad above the pedal clutch
that switch enables the starter relay just like all cars, manual
so you an not start engine in gear.

those other problems are other causes.
IMMO key must not be ignored. padlock
thee users guide tells you what the lamp does. (lost that?)
lost the second ignition key? from when car was new.
some cars dim HL lamps to have extra power to crank the engine, a super good features on all cars with it.
you just buy a dead car, or did it just fail out of the blue.??????????
learn what RAP is in the manual.?
key off radio works for delay10mn them or ends door open
page 2-18 in the manual

now IMMO words same manual free, to all chev. owners.
Page 2-15 actual
to start the engine closes door or IMMO Passlock
will fail.
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock®
is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled
During normal operation, the security light will go off
approximately three seconds after the key is turned to
RUN following an engine start.
If the engine stalls and the security light flashes, wait
until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock®system is not working properly and must be serviced by yourdealer.

but the clutch switch is failing and can be jumpered easy, your paper clip. some switches have adjustment or are just fell loose.

Havery the battery checked first. Sounds like a dead cell, otherwise you could not jump start it. Check fuse on radio.

Must either be the ignition switch itself failed, and/or the ignition relay has failed.

The BLUE/RED wire from your ignition switch provides power to your cigarette lighter and your radio via the 15 Amp "CIG" fuse and the 7.5 Amp "RADIO" fuse in the fuse block under the left end of the dash in the kick panel.

However, this wire will not have any power with the ignition switch removed and therefore would not have been able to blow any fuses with the switch removed. The two fuses that the BLUE/RED wire go to will also not cause your engine to not start.

If your radio does not work and your engine does not start, you probably accidently grounded the WHITE wire. This is one of the TWO power wires going INTO the ignition switch. The other power wire is the BLACK/RED.
The WHITE wire gets power from the 40 Amp "AM1" fuse and the BLACK/RED wire gets power from the 30 Amp "AM2" fuse. Both of these fuses are located in the F.1 fusable link box in the engine compartment at the battery.

Maybe the ignition switch burned up. A lot of juice travels through them and it has happened.
What is confusing is, lights will work without the switch. You should be able to turn lights on without the key in the ignition. But a radio normally needs the ignition turned to ACC (accessory) or ON. And some when left on don't turn off with the key off until the door is opened.

Possibly the ignition melted and is affected to where the radio still gets power as if it was in the ACC position

If the starter cranks but the engine won't start, there could be wide range of problems. Here are some of the most common:
- Problems with fuel delivery system (e.g bad fuel pump, fuel pump relay, clogged fuel screen, etc.)
- Problem with engine electronics (e.g crank sensor, cam sensor, air flow sensor, power relay, engine computer, etc.)
- Ignition system problems, especially on older vehicles with the distributor (e.g bad ignition coil, commutator, rotor, distributor cap, etc.)
- Defective ignition switch
- Problems with vehicle security system
- Internal engine problems (e.g broken timing belt or gear, low compression, etc.)

Make sure that you have fuel in the tank. It may be that your vehicle fuel gauge isn't working properly.The first signs that there is too little fuel in the tank are occasional lugging, loss of power, and a louder, irregular sound of the electric fuel pump coming out from the fuel tank

try another door or tailgate to use key to lock/unlock.the one you tried may have a bad switch

Check the engine relay by tapping it a little . relays sometimes get stuck.It is in the engine compartment at the fusebox.Remove it from the box and clean it. If your car starts. replace the relay.

I suspect the ignition switch is malfunctioning.
