hello everyone first time here. 2011 vw tiguan,came in running poorly mil on. found a list codes,started with misfire because i could feel it missing.found a bad coil replaced coil and spark plugs. car still running rough than found vac.leak at intake manifold runner. so replaced manifold intake valves were ok so did not clean. still running rough found code for low pressure at fuel rail. verified supply pump fuel pressure 85 psi. within spec. replaced mechanical fuel pump and road test. still runs rough and no power and engine pinging. drove back to service bay. turned off vehicle and tried to restart but now it is a no start. tested for power at injector harness below intake manifold KOEO no power found. no power present while cranking checked wires to pcm and did not find short or open. no immobilizer codes present. question is, is there anything that would shut down all injectors? or is it just a bad pcm.

I believe that if the crank sensor is not sending pulses, then the ECU shuts down the injectors, spark and all that. It needs to see valid crank signal.

How about an autoscan please. Help is always offered at Ross-warts to those who supply the required autoscan.
