My RDX will start quickly every time but will only stay running for about 3-5 seconds. I’ve replaced the crank sensor and checked the fuel system. Put a gauge in line at the fuel rail. The pump put out 53psi and no leaks through the injectors. Pump pressure was 35-38 psi for the 3-5 seconds it runs. Looking for any suggestions about what to try next. Thanks

 

Hello.. I am having the same issue with my 2007 RDX ...it starts fine ... cluster lights light up then a couple of seconds later engine shuts off...lights on dash remain on.. scratching my head since I just came back from Acura dealer and they gave it a synthetic oil change and passed nys inspection ...was told the tech said this car was in great shape for the year ( I don't think he was talking about the leather seats).. came home and adjusted radio settings car turned on fine ..2nd time I tried turning it on that is when it started shutting off immediately ..did this a dozen times before going into a deep thinking mode
