I need help on my car. I've got a 2011 g37x 3.7. three weeks ago I was driving home and the car straight up died. Electrical works, but the engine won't crank over. I took it to the dealer and they said it "could" be a intake cam sprocket, with chain damage and it was 6 grand just to look into it with possibly needing na new engine for 13 grand.
My mechanic says it wants to start with ether (starting fluid) and that the codes generated might be from just trying to keep cranking it over. He tested everything from the power to the pump, to having fuel at the rail.. all fuses check out also.
Lastly, he says that there is no pulse on the fuel injectors and that is the primary reason for the no start.
Does anyone know where to start with diagnosing a no-pulse symptom or perhaps have had experienced this in the past? We are stumped & any help is greatly appreciated.
I find it amazing that both you and your so called mechanic does not follow the troubleshooting steps in the FSM?

Will the engine turn over with a good battery with the spark plugs removed?
If not then the dealer assessment was probably correct.
How often do you check your oil?
Did you run out of oil in the crankcase?
No pulse on the fuel injectors is the result of the engine not turning over.
The amount of fuel injected from the fuel injector is
determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). T
he amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from t
he crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the mass air flow sensor
When my 1966 Volkswagen Beedle originally purchased in Germany while in the US Army suddenly died on the Grand Central Parkway in Jamaica Queens, NY I also had it towed to the VW dealer.
A valve had broken and fell into a cylinder. I don't recall the price to fix it but the dealer gave me $500 towards a brand new 69 VW that had an out the door price of $2050.
I returned the following day and drove out with a brand new VW very happy.
Check with the dealer how much they'll give you on a trade-in?
