my vehicle after a few days in the paint shop does not start, just a wash and a pressure down and after that do not want to start, first had error in the sensor of the crankshaft (P0336 and P0339) changed the sensor and now gives errors.
It turns on perfectly after disconnecting the battery for a few minutes, then the fuel gauge goes to the end to the right and then turns off and does not turn on anymore, only when it redials the correct gas level, but to few minutes it goes turn off again.
and change the relay of the gas pump, check cables and I still do not find the problem

 

Did you get water under the dizzy cap? Camshaft position sensor is in there.
