My car has been acting weird the last couple days, and when im on the highway the check engine light goes on for a few seconds then will go off. When i was at a stop light today the engine reved a little then died. When im driving sometimes and i push on the gas sometimes it takes a second or two for the power to kick in. I scanned the computer for codes and it brought up 542 like 3 times, "fuel pump secondary circuit failure". Does this sound like the problem or did I interpret the scan wrong? I recently cleaned the MAF sensor and replaced the intake and coolant sensor. I had the fuel filter changed too.
