HELLO EVERYONE, I HAVE A 2006 MAZDASPEED 6 THAT WILL NOT START, ANY INFO WILL BE GREATLY APPRECIATED! I CAN NOT FIGURE OUT WHY IT WONT START. THE SYMPTOMS OF THE CAR ARE: CRANKS BUT WONT FIRE. I JUST REPLACED THE FUEL PUMP WITH A NEW ONE RAN FINE FOR 3 DAYS WHEN I LEFT MY CAR TO IDLE I GOT BACK IN AND WENT TO TAKE OFF THEN IT DIED. I FINALLY GOT IT TO START DROVE HOME AND PARKED IT. AFTER A DAY OF SITTING IT WOULD START UP I DROVE IT FOR MAYBE 10 MINS THEN IT WOULD DIE ( IF I WERE TO STOP AT A RED LIGHT AND GO TO TAKE OFF IT WOULD DIE) I THOUGHT I GOT A BAD FUEL PUMP SO I PUT THE OLD ONE BACK IN STILL NOTHING, CRANKS BUT WONT START SO I BUT THE NEW BACK IN. I CHECKED THE HIGH PRESSURE FUEL PUMP INTERNALS SEEMED TO BE OKAY BUT I INSTALLED NEW ONES SINCE I WAS TAKING IT APART, AND YET AGAIN NOTHING. CRAZY THING IS THERES NO CHECK ENGINE LIGHT..

ANY ADVISE WOULD HELP I JUST WANT TO DRIVE MY BABY AGAIN

 

Welcome! I read your writing here. You should go for a new one.

 

Get the fuel pressure tested at the fuel rail. Get a diagnostic code check. ( not all codes bring the light on )
