CRANKS ONLY ONCE AND NO CRANK FOR 24 HOURS

[STEVE MIESEN]

My 2008 lexus 460 cranks starts  immediately ,won't start and does not crank again for 24 hours and does the same thing. It will fire up fora second.and then dies.

Mass airflow sensor? Try unplugging it, car should run with it unplugged if you don’t touch the throttle.

Same issue with my 07 ls460. Did you ever figure this problem out?

thanks

I'm pretty sure that there should be some trouble codes associated with this behavior. Get the codes read and check back with us.

SAME ISSUE HERE.  WILL ONLY CRANK ONCE A DAY, STARTS FOR HALF A SECOND THEN DIES REALLY QUICKLY AND BUTTON GOES NONRESPONSIVE.  BATTERY CHARGED, MAF SENSORS PLUGGED AND UNLPUGGED MAKE NO DIFFERENCE.  ECM HAS NO COMMUNICATION WHEN I TRY TO SCAN IT, AND THERE IS NO CHECK ENGINE LIGHT EVER ILLUMINATED EVEN WHEN THE VEHICLE IS POWERED ON AND ALL THE LIGHTS LIGHT UP FOR A SECOND.  IM THINKING ITS THE ECM GOING BAD, BECAUSE IF IT WAS A FUSE OR RELAY I WOULDNT GET THE RANDOM CRANK AND START. ANY ONE FIND AN ISSUE YET?
