2001bmw 740i non start ign lights on new batt and key still won't start ?

SOURCE: 2008 nissan sentra has occasional starting issues.

Could be bad battery or Somthing going on with the main fuse box.  Another thing to check is your ground wires.  If they are loose, you can not complete the circut.

Bad solenoid

Testimonial: "THANK YOU SO MUCH FOR GIVING US AN IDEA WHERE TO START LOOKING."

SOURCE: 1995 BMW 525i. Car will not start or turn over.

I had the same problem, after having the car towed to four Seasons, it was discovered that the electrical portion of the ignition switch was defective. Works like a charm. Part number 61 32 8 356 026 Hope this will help.

Hi there:
You will have to pinpoint what the engine is missing Spark / Fuel / Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
