2005 E320 CDI - No Start
Car would not start one day. No previous symptoms. Since no start, has been sitting in the garage for 3-4 months. After a fully charged battery the starter is turning at the right RPM, but the engine doesn't even try to start.
In tank fuel pump is bringing lots of fuel to the filter which looks newer, and i cracked an injector line on the common rail and it has lots of fuel there as well. Fuel rail pressure when cranking according to my MaxiDas scantool shows 475-500bar. Spec is 430-470bar.
Fuel is confirmed diesel.
When checking injector pulse, i get good injector pulse for 4-6 pulses, and then it stops pulsing. I am assuming the ECU is seeing the misfire and shutting them down.
Compression check reveals pretty even compression readings from 325-375psi. Mostly around 375psi. I checked cylinders #2, #3, and #6. The only ones my tester would fit in easily.
With my noid light hooked up to an injector, and the glow plug removed, the compression and injector pulse seem to be in time.
The car is inside the garage at 10-20*C so the glow plugs I am ignoring for now.
Codes are as follows.
2197-4 Quantity control valve signal line interipted (Y94)
2679-4 Fuel filter water level sensor faulty (found this one unplugged)
The glow plug faults are hard faults.
2136-4 Glow plug 4 fault
2137-4 Glow plug 5 fault
2138-4 Glow plug 6 fault
After being cleared, the following return after 1 or 2 starting attempts.
0190-1 Fuel rail pressure sensor voltage too high (B4/6)
2500-4 Pressure control valve signal interupted (Y74)
2051-1 Fuel rail pressure low
I can't find any information on this car so any help is appreciated.
