Okay guys so I’ve pretty much have checked everything I can think of and I still can’t figure out why my 2007 328i isn’t starting. I have crank but no start. Any additional help or input would be highly appreciated!
- Fuel pump is good and it’s new. Primes and voltage is good. Fuel rail has pressure.
- Did a spark test. I am getting spark.
- Starter is new.
- Swapped fuel pump relay.
- All 6 spark plugs are new.
- VANOS solenoids are new.
- Crankshaft position sensor is new.
- Battery is new along with power distribution box
So far no luck. It’s leading me to believe it might be issues with the CAS and DME. Maybe communication between both modules? Either that or last thing I can think of, is a timing issue or something with the VANOS units. I’ll have to inspect it when I take off the valve cover. I know these cars aren’t known for timing issues but it could be a possibility.
I’ve cleared all the codes, and here’s what I’ve got back after rescanning and a few cranks.
- 29DB - Smooth running, segment timing
- 2A3F - Valvetronic, actuator motor: power supply
- 2A99 - Crankshaft - exhaust camshaft, reference
- 2A77 - Control module, internal fault: Valvetronic output stage
- CAS | A0B4 - Engine start, starter operation
- CAS | A0B2 - Supply, terminal 30e/30L
Any input guys?
Literally losing my mind
