7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Stumped!!!

Help
I was getting misfire codes so I changed the coil packs and the spark plugs. First I was trying to save money and put in NGK and some generic coil packs....I know I know dumb. Anyways so my car started to run really rough, so I changed the coil packs and the spark plugs again with bosch parts. Now my car will not start at all or even go into neutral. There are no codes coming up I am totally stumped as to what is going on with my car I have a 2007 750li. Please anyone with any ideas I need help.

Does your car crank?
First. Check the battery. If the battery is good. Check for Spark. Than check the fuel rails for fuel pressure. IVM module might be something you might look in to. Some of the options.

It will crank it seems like it's just not catching to actually start up. We got a new battery last month. My Indy checked all the spark plugs and theres a spark he also checked the fuel lines and we have pressure. We have not checked the IVM module. What are some of the symptoms of that going out?

"Integrated Voltage Supply Module) this module has a series of fuses and relays that supply and control the DME, fuel injectors, O2 sensors and the Ignition Coils." But if you are getting spark and your car cranks it might be something else. But this module is cheap so it wont hurt your pocket vs other things.

The IVM would be a good place to start, & easy to replace. Around 120.00 for the module.

Is there any kind of test for that? Or symptom?

The IVM has around 8 fuses in it that control functions of the DME. It is located under the cabin air filter in the main power box. Remove the IVM & inspect the fuses & signs of any water contamination. It either works, or it does not work. It is probably the #1 item from keeping the engine from starting.
